Galaxies and their dark-matter haloes have posed several challenges to the dark energy
plus cold dark matter (Λ CDM) cosmological model. These discrepancies between …

We review the physics and phenomenology of wave dark matter: a bosonic dark matter
candidate lighter than about 30 eV. Such particles have a de Broglie wavelength exceeding …

Horizon-scale images of black holes (BHs) and their shadows have opened an
unprecedented window onto tests of gravity and fundamental physics in the strong-field …

We present the full public release of all data from the TNG100 and TNG300 simulations of
the IllustrisTNG project. IllustrisTNG is a suite of large volume, cosmological, gravo …

As they grow, galaxies can transition from irregular/spheroidal with 'bursty'star formation
histories (SFHs), to discy with smooth SFHs. But even in simulations, the direct physical …

We study the strong gravitational lensing effect around rotating black holes in different
gravity theories. By calculating the deflection angle of strong gravitational lensing, we …

The development of methods and algorithms to solve the N-body problem for classical,
collisionless, non-relativistic particles has made it possible to follow the growth and …

We perform a high-resolution cosmological zoom-in simulation of a Milky Way (MW)–like
system, which includes a realistic Large Magellanic Cloud analog, using a large differential …

We present the HI emission project within the MIGHTEE survey, currently being carried out
with the newly commissioned MeerKAT radio telescope. This is one of the first deep, blind …

We examine the formation of dark matter (DM) cores in dwarf galaxies simulated with the
eagle model of galaxy formation. As in earlier work, we find that the star formation (SF) gas …
