Abstract The Widefield ASKAP L-band Legacy All-sky Blind surveY (wallaby) is a next-
generation survey of neutral hydrogen (H i) in the Local Universe. It uses the widefield, high …

We present the hestia simulation suite: High-resolutions Environmental Simulations of The
Immediate Area, a set of cosmological simulations of the Local Group. Initial conditions …

ABSTRACT WEAVE, the new wide-field, massively multiplexed spectroscopic survey facility
for the William Herschel Telescope, saw first light in late 2022. WEAVE comprises a new 2 …

Although structures in the Universe form on a wide variety of scales, from small dwarf
galaxies to large super clusters, the generation of angular momentum across these scales is …

Context. A significant fraction of the predicted baryons remain undetected in the local
Universe. We adopted the common assumption that a large fraction of the missing baryons …

Galaxy cluster outskirts are described by complex velocity fields induced by diffuse material
collapsing towards filaments, gas, and galaxies falling into clusters, and gas shock …

We study the alignments of galaxy spin axes with respect to cosmic web filaments as a
function of various properties of the galaxies and their constituent bulges and discs. We …

Galaxy formation theories predict that galaxy shapes and angular momenta have
nonrandom alignments with the cosmic web. This leads to so-called intrinsic alignment …

We present a statistical study of the filamentary structures of the cosmic web in the large
hydro-dynamical simulations Illustris-TNG, Illustris, and Magneticum at redshift z= 0. We …

Stellar halos in early-type galaxies (ETGs) are shaped by their accretion and merger
histories. We use a sample of 1114 ETGs in the TNG100 simulation of the IllustrisTNG suite …
