The directions of the galaxy angular momenta can be predicted from the initial conditions of the early Universe through the tidal torque. In simulations, these directions are well preserved through cosmic time, consistent with expectations of angular momentum conservation. We find evidence, statistically significant at ~2.7σ, of correlation between observed oriented directions of galaxy angular momentum vectors and their predictions based on the initial density field reconstructed from the positions of Sloan Digital Sky Survey galaxies. This study presents evidence for a correlation between directions of galaxy angular momenta and cosmic initial conditions, and opens a way to use measurements of galaxy spins to probe fundamental physics in the early Universe.

We present two galaxy shape catalogues from the Dark Energy Survey Year 1 data set, covering 1500 deg<SUP>2</SUP> with a median redshift of 0.59. The catalogues cover two main fields: Stripe 82, and an area overlapping the South Pole Telescope survey region. We describe our data analysis process and in particular our shape measurement using two independent shear measurement pipelines, METACALIBRATION and IM3SHAPE. The METACALIBRATION catalogue uses a Gaussian model with an innovative internal calibration scheme, and was applied to riz bands, yielding 34.8M objects. The IM3SHAPE catalogue uses a maximum-likelihood bulge/disc model calibrated using simulations, and was applied to r-band data, yielding 21.9M objects. Both catalogues pass a suite of null tests that demonstrate their fitness for use in weak lensing science. We estimate the 1σ uncertainties in multiplicative shear calibration to be 0.013 and 0.025 for the METACALIBRATION and IM3SHAPE catalogues, respectively.

We present new simulations of the formation of the Magellanic Stream based on an updated first-passage interaction history for the Magellanic Clouds, including both the Galactic and Magellanic Coronae and a live dark matter halo for the Milky Way. This new interaction history is needed because previously successful orbits need updating to account for the Magellanic Corona and the loosely bound nature of the Magellanic Group. These orbits involve two tidal interactions over the last 3.5 Gyr and reproduce the Stream's position and appearance on the sky, mass distribution, and velocity profile. Most importantly, our simulated Stream is only ~20 kpc away from the Sun at its closest point, whereas previous first-infall models predicted a distance of 100-200 kpc. This dramatic paradigm shift in the Stream's 3D position would have several important implications. First, estimates of the observed neutral and ionized masses would be reduced by a factor of ~5. Second, the stellar component of the Stream is also predicted to be &lt;20 kpc away. Third, the enhanced interactions with the MW's hot corona at this small distance would substantially shorten the Stream's lifetime. Finally, the MW's UV radiation field would be much stronger, potentially explaining the Hα emission observed along most of the Stream. Our prediction of a 20 kpc Stream could be tested by searching for UV absorption lines toward distant MW halo stars projected onto the Stream.

Hub-filament systems (HFSs) are potential sites of formation of star clusters and high mass stars. To understand the HFSs and to provide observational constraints on current theories that attempt to explain star formation globally, we report a study of the region associated with G326.27-0.49 using infrared data of dust continuum and newly obtained observations on molecular tracers using the APEX (Atacama Pathfinder EXperiment) telescope. We use the spectroscopic observations to identify velocity-coherent structures (filaments and clumps) and study their properties at a resolution of 0.4 pc. The region contains two main velocity components: first component shows four filaments between -63 and -55 km s<SUP>-1</SUP> forming a spiral structure converging in a hub, the second filamentary component at ~-72 km s<SUP>-1</SUP> harbours a massive young stellar object (YSO) and possibly interacts with the hub. The clumps harbouring the three main YSOs in the region are massive (187-535 M<SUB>⊙</SUB>), have luminosities consistent with B-type stars, have central densities of ~10<SUP>6</SUP> cm<SUP>-3</SUP>, and drive large outflows. Majority of the velocity-coherent clumps in the region shows virial parameters between 2 and 7, which considering the detection of protostars implies collapse to be gradual. We conclude that the region consists of a network of filaments through which mass accretes (~10<SUP>-4</SUP> M<SUB>⊙</SUB> yr<SUP>-1</SUP>) onto the hub. The hub and some of the ends of filaments appear to be undergoing collapse to form new stars. This study identifies a target region for future high-resolution studies that would probe the link between the core and filament evolution.

Strong gravitational lens system catalogues are typically used to constrain a combination of cosmological and empirical lens mass model parameters, even though the simplest singular isothermal sphere (SIS) models yield a $\chi^2$ per degree of freedom $\simeq 2$. To date, this problem has been alleviated by introducing additional empirical parameters in the extended power law (EPL) models and constraints from high resolution imagery. The EPL parameters are taken to vary from lens to lens, rather than defining universal lens profiles. We investigate these lens models using Bayesian methods through a novel alternative that treats spatial curvature via the non-FLRW Timescape cosmology. We apply Markov Chain Monte Carlo methods using the catalogue of 161 lens systems of Chen et al (arXiv:1809.09845) to simulate large mock catalogues for: (i) the standard $\Lambda$CDM model with zero spatial curvature; and (ii) the Timescape model. Furthermore, this methodology can be applied to any cosmological model. In agreement with previous results we find that in combination with SIS parameters, models with zero FLRW spatial curvature fit better as the free parameter approaches an unphysical empty universe, $\Omega_{\rm M0}\to0$. By contrast, the Timescape cosmology is found to prefer parameter values in which its cosmological parameter, the present void fraction, is driven to $f_{\rm v0}\to0.73$ matches, close to values found to best fit independent cosmological data sets: supernovae Ia distances and cosmic microwave background. This conclusion holds for a large range of seed values $f_{\rm v0}\to0.73\in\{0.1,0.9\}$, and for Timescape fits to both Timescape and FLRW mocks. Regardless of cosmology, unphysical estimates of the distance ratios given from power-law lens models result in poor goodness of fit. Nonetheless, the results are consistent with non-FLRW spatial curvature evolution.

Both asteroids and comets can come close to the Earth's orbit. Any dust released from any them will form a meteoroid stream whose orbit may allow the Earth to pass through it. If this takes place, the ablation of the meteoroids in the Earth's atmosphere will be observed as meteors. The various ways in which both showers and the related stream can be identified from these observations are described. In this region, orbital evolution is rapid due to a number of effects, so that orbits will progressively diverge from the original orbit and the showers become weaker, making the identification of the stream and its parent more tenuous. Catalogues of recognized showers and streams are listed together with the updated orbital characteristics of all the streams. Eventually a stream will lose its identity and the meteoroids merge into the sporadic background. Methods for determining whether the sporadic meteors originate from comets or asteroids based on their orbits are discussed. Finally, they merge into the zodiacal dust clouds and the observations of these clouds are discussed together with an overview of their main characteristics.

Dark matter (DM) haloes can be subject to gravothermal collapse if DM is not collisionless but has strong self-interactions. When the scattering can efficiently transfer heat from the centre to the outskirts, the central region of the halo collapses and reaches densities much higher than those for collisionless DM. This phenomenon is potentially observable in studies of strong lensing. Current theoretical efforts are motivated by observations of surprisingly dense substructures. A comparison with them requires accurate predictions. One method to obtain such predictions is to use N-body simulations. The collapsed haloes are extreme systems that pose severe challenges to state-of-the-art codes used to model self-interacting dark matter (SIDM). We investigate the root of such problems with a focus on energy non-conservation. We run N-body simulations with and without DM self-interactions of an isolated DM-only halo and change numerical parameters relevant to the accuracy of the simulation. We find that not only the numerical scheme for the DM self-interactions can lead to energy non-conservation but also the modelling of gravitational interaction and the time integration are problematic. The issues we found are: (a) particles changing their time step in a non-time-reversible manner; (b) the asymmetry in the tree-based gravitational force evaluation; (c) SIDM velocity kicks break the symplectic nature and time symmetry. Tuning the parameters of the simulation to achieve a high accuracy allows for conserving energy not only at early stages of the evolution but also at late ones. However, the cost of the simulations becomes prohibitively large. Some problems making the simulations of the gravothermal collapse phase inaccurate, can be overcome by choosing appropriate numerical schemes. However, others remain challenging. Our findings motivate further work on addressing these challenges.
