The hot big bang is often considered as the origin of all matter and radiation in the Universe. Primordial nucleosynthesis provides strong evidence that the early Universe contained a hot plasma of photons and baryons with a temperature T >MeV . However, the earliest probes of dark matter originate from much later times around the epoch of structure formation. In this work we describe a scenario in which dark matter (and possibly dark radiation) can be formed around or even after primordial nucleosynthesis in a second big bang, which we dub the "dark big bang." The latter occurs through a phase transition in the dark sector that transforms dark vacuum energy into a hot dark plasma of particles; in this paper we focus on a first-order phase transition for the dark big bang. The correct dark matter abundance can be set by dark matter cannibalism or by pair annihilation within the dark sector followed by a thermal freeze-out. Alternatively ultraheavy "dark-zilla" dark matter can originate directly from bubble collisions during the dark big bang. We will show that the dark big bang is consistent with constraints from structure formation and the cosmic microwave background if it occurred when the Universe was less than one month old, corresponding to a temperature in the visible sector above O (keV ). While the dark matter evades direct and indirect detection, the dark big bang gives rise to striking gravity wave signatures to be tested at pulsar timing array experiments. Furthermore, the dark big bang allows for realizations of self-interacting and/or warm dark matter, which suggest exciting discovery potential in future small-scale structure observations.

The abundance of cold molecular gas plays a crucial role in models of galaxy evolution. While deep spectroscopic surveys of CO emission lines have been a primary tool for measuring this abundance, the difficulty of these observations has motivated alternative approaches to studying molecular gas content. One technique, line intensity mapping, seeks to constrain the average molecular gas properties of large samples of individually undetectable galaxies through the CO brightness power spectrum. Here we present constraints on the cross-power spectrum between CO intensity maps and optical galaxy catalogs. This cross-measurement allows us to check for systematic problems in CO intensity mapping data, and validate the data analysis used for the auto-power spectrum measurement of the CO Power Spectrum Survey. We place a 2σ upper limit on the band-averaged CO-galaxy cross-power of P <SUB>×</SUB> &lt; 540 μK h<SUP>-3</SUP> Mpc<SUP>3</SUP>. Our measurement favors a nonzero &lt;T <SUB>CO</SUB>&gt; at around 90% confidence and gives an upper limit on the mean molecular gas density at z ~ 2.6 of 7.7 × 10<SUP>8</SUP> M <SUB>⊙</SUB> Mpc<SUP>-3</SUP>. We forecast the expected cross-power spectrum by applying a number of literature prescriptions for the CO luminosity-halo mass relation to a suite of mock light cones. Under the most optimistic forecasts, the cross-spectrum could be detected with only moderate extensions of the data used here, while more conservative models could be detected with a factor of 10 increase in sensitivity. Ongoing CO intensity mapping experiments will target fields allowing for extensive cross-correlation analysis and should reach the sensitivity required to detect the cross-spectrum signal.

We present a turnkey solution, ready for implementation in numerical codes, for the study of linear structure formation in general scalar-tensor models involving a single universally coupled scalar field. We show that the totality of cosmological information on the gravitational sector can be compressed — without any redundancy — into five independent and arbitrary functions of time only and one constant. These describe physical properties of the universe: the observable background expansion history, fractional matter density today, and four functions of time describing the properties of the dark energy. We show that two of those dark-energy property functions control the existence of anisotropic stress, the other two — dark-energy clustering, both of which are can be scale-dependent. All these properties can in principle be measured, but no information on the underlying theory of acceleration beyond this can be obtained. We present a translation between popular models of late-time acceleration (e.g. perfect fluids, f(R), kinetic gravity braiding, galileons), as well as the effective field theory framework, and our formulation. In this way, implementing this formulation numerically would give a single tool which could consistently test the majority of models of late-time acceleration heretofore proposed.

This pre-release is a functional first release of Vlasiator with support for NVIDIA GPUs via CUDA and AMD GPUs via HIP/ROCm. The same branch also supports building for CPUs just as before. Slight differences in output show up as a result of differing summation orders in e.g. moments reduction, but testpackage tests all pass with acceptable numerical diffs. Known issues: Block adjustment in acceleration can still be slow. VDF-based data reducers are somewhat slow. AMD performance is low and requires a mempool for operations (e.g. https://github.com/sfantao/vlasiator-mempool). Planned improvements include support for more robust memory management libraries. Field solver and ionospheric grid solver have not yet been ported to GPUs. GPU RDMA may not work on all systems, leading to poor MPI performance. CUDA compute-sanitizer reports several invalid context errors on launch; these can be ignored. This introduces the Hashinator library (https://github.com/fmihpc/hashinator) as a required submodule. Make sure to initialize and pull it as well. GPU compilation should use a GPU-compatible compiler for all objects; see e.g. MAKE/Makefile.mahti_cuda for instructions on how to set up a compiler.

The magnetic Rayleigh-Taylor instability is a fundamental instability of many astrophysical systems, and recent observations are consistent with this instability developing in solar prominences. Prominences are cool, dense clouds of plasma that form in the solar corona that display a wide range of dynamics of a multitude of spatial and temporal scales, and two different phenomena that have been discovered to occur in prominences can be understood as resulting from the Rayleigh-Taylor instability. The first is that of plumes that rise through quiescent prominences from low density bubbles that form below them. The second is that of a prominence eruption that fragments as the material falls back to the solar surface. To identify these events as the magnetic Rayleigh-Taylor instability, a wide range of theoretical work, both numerical and analytical has been performed, though alternative explanations do exist. For both of these sets of observations, determining that they are created by the magnetic Rayleigh-Taylor instability has meant that the linear instability conditions and nonlinear dynamics can be used to make estimates of the magnetic field strength. There are strong connections between these phenomena and those in a number of other astro, space and plasma systems, making these observations very important for our understanding of the role of the Rayleigh-Taylor instability in magnetised systems.

Here we present high-resolution NH<SUB>3</SUB> observations with the Very Large Array and Green Bank Telescope toward a prestellar core. These observations show an outer region with a fractional NH<SUB>3</SUB> abundance of X(NH<SUB>3</SUB>) = (1.975 ± 0.005) × 10<SUP>-8</SUP> (±10% systematic), but it also reveals that, after all, the X(NH<SUB>3</SUB>) starts to decrease above a H<SUB>2</SUB> column density of ≈2.6 × 10<SUP>22</SUP> cm<SUP>-2</SUP>. We derive a density model for the core and find that the break point in the fractional abundance occurs at the density n(H<SUB>2</SUB>) ~ 2 × 10<SUP>5</SUP> cm<SUP>-3</SUP>, and beyond this point the fractional abundance decreases with increasing density, following the power law n <SUP>-1.1</SUP>. This power-law behavior is well reproduced by chemical models where adsorption onto grains dominates the removal of ammonia and related species from the gas at high densities. We suggest that the break-point density changes from core to core depending on the temperature and the grain properties, but that the depletion power law is anyway likely to be close to n <SUP>-1</SUP> owing to the dominance of accretion in the central parts of starless cores.

From the archival data of the BU-FCRAO $^{13}$ CO GRS, we measure the radial profiles of column density and turbulent velocity dispersion from the centers of molecular clouds outward into the surrounding diffuse molecular ISM. Averaged across spatial scales, the profiles are consistent with turbulence that is on average in hydrostatic equilibrium. We measure the turbulent kinetic energy (KE) and the gravitational potential energy (GE) within and the pressure energy (PE) outside the clouds. The distribution of the sum 2KE-|GE|-PE has a mean near zero indicating approximate virial equilibrium. The average pressure energy is consistent with estimates of the pressure of the multiphase ISM at the Galactic mid-plane. If the dynamical time scale of the turbulence scales with its crossing time, this apparent equilibrium may result from the rapid virialization of the KE and GE with respect to changes in PE. In a snapshot, the clouds appear to be in virial equilibrium within a confining pressure. However, the duration of the equilibrium is approximately the crossing time. An analysis of Larson's scaling relationships of line width and column density finds no correlation. Tthe inference of constant column density with cloud size is a misinterpretation of this lack of correlation.

This work presents an interferometric study of the massive-binary fraction in the Orion Trapezium cluster with the recently comissioned GRAVITY instrument. We observed a total of 16 stars of mainly OB spectral type. We find three previously unknown companions for θ<SUP>1</SUP> Ori B, θ<SUP>2</SUP> Ori B, and θ<SUP>2</SUP> Ori C. We determined a separation for the previously suspected companion of NU Ori. We confirm four companions for θ<SUP>1</SUP> Ori A, θ<SUP>1</SUP> Ori C, θ<SUP>1</SUP> Ori D, and θ<SUP>2</SUP> Ori A, all with substantially improved astrometry and photometric mass estimates. We refined the orbit of the eccentric high-mass binary θ<SUP>1</SUP> Ori C and we are able to derive a new orbit for θ<SUP>1</SUP> Ori D. We find a system mass of 21.7 M<SUB>⊙</SUB> and a period of 53 days. Together with other previously detected companions seen in spectroscopy or direct imaging, eleven of the 16 high-mass stars are multiple systems. We obtain a total number of 22 companions with separations up to 600 AU. The companion fraction of the early B and O stars in our sample is about two, significantly higher than in earlier studies of mostly OB associations. The separation distribution hints toward a bimodality. Such a bimodality has been previously found in A stars, but rarely in OB binaries, which up to this point have been assumed to be mostly compact with a tail of wider companions. We also do not find a substantial population of equal-mass binaries. The observed distribution of mass ratios declines steeply with mass, and like the direct star counts, indicates that our companions follow a standard power law initial mass function. Again, this is in contrast to earlier findings of flat mass ratio distributions in OB associations. We excluded collision as a dominant formation mechanism but find no clear preference for core accretion or competitive accretion.

Nutrient-Phytoplankton-Zooplankton-Detritus (NPZD) models, describing the interactions between phytoplankton, zooplankton systems and their ecosystem, are used to predict their ecological and evolutionary population dynamics. These organisms form the base of two trophic levels of aquatic ecosystems. Hence understanding their population dynamics and how disturbances can affect these systems are crucial. Here, starting from a base NPZ modeling framework, we incorporate harmful affects of phytoplankton overpopulation on zooplankton - representing a crucial next step in harmful algal bloom (HAB) modeling - and split the nutrient compartment to formulate a NPZD model. We then mathematically analyze the NPZ system upon which this new model is based, including local and global stability of equilibria, Hopf bifurcation condition and forward hysteresis, where the bi-stability occurs with multiple attractors. Finally, we extend the threshold analysis to the NPZD model, which displays forward hysteresis with bi-stability and examine ecological implications after incorporating seasonality and ecological disturbances. Ultimately we quantify ecosystem health in terms of the relative values of the robust persistence thresholds for phytoplankton and zooplankton and find (i) ecosystems sufficiently favoring phytoplankton are vulnerable to both HABs and (local) zooplankton extinction (ii) even healthy ecosystems are extremely sensitive to nutrient depletion over realtively short time scales.

We use a semianalytic approach that is calibrated to N-body simulations to study the evolution of self-interacting dark matter cores in galaxies. We demarcate the regime where the temporal evolution of the core density follows a well-defined track set by the initial halo parameters and the cross section. Along this track, the central density reaches a minimum value set by the initial halo density. Further evolution leads to an outward heat transfer, inducing gravothermal core collapse such that the core shrinks as its density increases. We show that the timescale for the core collapse is highly sensitive to the outer radial density profile. Satellite galaxies with significant mass loss due to tidal stripping should have larger central densities and significantly faster core collapse compared to isolated halos. Such a scenario could explain the dense and compact cores of dwarf galaxies in the Local Group like Tucana (isolated from the Milky Way), the classical Milky Way satellite Draco, and some of the ultrafaint satellites. If the ultimate fate of core collapse is black hole formation, then the accelerated timescale provides a new mechanism for creating intermediate-mass black holes.

Context. We present the second public data release of the VISTA EXtension to Auxiliary Surveys (VEXAS), where we classify objects into stars, galaxies, and quasars based on an ensemble of machine learning algorithms. <BR /> Aims: The aim of VEXAS is to build the widest multi-wavelength catalogue, providing reference magnitudes, colours, and morphological information for a large number of scientific uses. <BR /> Methods: We applied an ensemble of thirty-two different machine learning models, based on three different algorithms and on different magnitude sets, training samples, and classification problems (two or three classes) on the three VEXAS Data Release 1 (DR1) optical and infrared (IR) tables. The tables were created in DR1 cross-matching VISTA near-infrared data with Wide-field Infrared Survey Explorer far-infrared data and with optical magnitudes from the Dark Energy Survey (VEXAS-DESW), the Sky Mapper Survey (VEXAS-SMW), and the Panoramic Survey Telescope and Rapid Response System Survey (VEXAS-PSW). We assembled a large table of spectroscopically confirmed objects (VEXAS-SPEC-GOOD, 415 628 unique objects), based on the combination of six different spectroscopic surveys that we used for training. We developed feature imputation to also classify objects for which magnitudes in one or more bands are missing. <BR /> Results: We classify in total ≈90 × 10<SUP>6</SUP> objects in the Southern Hemisphere. Among these, ≈62.9 × 10<SUP>6</SUP> (≈52.6 × 10<SUP>6</SUP>) are classified as `high confidence' (`secure') stars, ≈920 000 (≈750 000) as `high confidence' (`secure') quasars, and ≈34.8 (≈34.1) million as `high confidence' (`secure') galaxies, with p<SUB>class</SUB> ≥ 0.7 (p<SUB>class</SUB> ≥ 0.9). The DR2 tables update the DR1 with the addition of imputed magnitudes and membership probabilities to each of the three classes. <BR /> Conclusions: The density of high-confidence extragalactic objects varies strongly with the survey depth: at p<SUB>class</SUB> &gt; 0.7, there are 11 deg<SUP>−2</SUP> quasars in the VEXAS-DESW footprint and 103 deg<SUP>−2</SUP> in the VEXAS-PSW footprint, while only 10.7 deg<SUP>−2</SUP> in the VEXAS-SM footprint. Improved depth in the mid-infrared and coverage in the optical and near-infrared are needed for the SM footprint that is not already covered by DESW and PSW. <P />The DR2 catalogues are also available at the CDS via anonymous ftp to <A href="http://cdsarc.u-strasbg.fr/">cdsarc.u-strasbg.fr</A> (ftp://130.79.128.5) or via <A href="http://cdsarc.u-strasbg.fr/viz-bin/cat/J/A+A/651/A69">http://cdsarc.u-strasbg.fr/viz-bin/cat/J/A+A/651/A69</A> <P />VEXAS is publicly available through the ESO Phase 3, <A href="https://archive.eso.org/scienceportal/home?data_collection=VEXAS">https://archive.eso.org/scienceportal/home?data_collection=VEXAS</A>

We present the results of a deep study of the neutron star (NS) population in the globular cluster M28 (NGC 6626), using the full 330 ks 2002-2015 ACIS data set from the Chandra X-ray Observatory and coordinated radio observations taken with the Green Bank Telescope (GBT) in 2015. We investigate the X-ray luminosity (L <SUB> X </SUB>), spectrum, and orbital modulation of the seven known compact binary millisecond pulsars in the cluster. We report two simultaneous detections of the redback PSR J1824-2452I (M28I) and its X-ray counterpart at L <SUB> X </SUB> = [8.3 ± 0.9] × 10<SUP>31</SUP> erg s<SUP>-1</SUP>. We discover a double-peaked X-ray orbital flux modulation in M28I during its pulsar state, centered around pulsar inferior conjunction. We analyze the spectrum of the quiescent NS low-mass X-ray binary to constrain its mass and radius. Using both hydrogen and helium NS atmosphere models, we find an NS radius of R = 9.2-11.5 km and R = 13.0-17.5 km, respectively, for an NS mass of 1.4 M <SUB>⊙</SUB> (68% confidence ranges). We also search for long-term variability in the 46 brightest X-ray sources and report the discovery of six new variable low-luminosity X-ray sources in M28.
