Ruffled Feathers: Merger-driven galaxy size growth and structural transformation in EAGLE
Kai Wang, Carlton Baugh, Sownak Bose +9
Galaxy mergers drive both the size growth and the transformation from discs to spheroids, yet the prescriptions used to model these processes in semi-analytic frameworks have not b…
Detection of a dark matter subhalo in the strongly lensed system PJ011646
Aristeidis Amvrosiadis, James W. Nightingale, Qiuhan He +12
We present a strong lensing analysis of the system PJ011646 using high-resolution (0.1 arcsec) Atacama Large Millimeter/submillimeter Array (ALMA) dust-continuum observations…
The abundance of thin dwarf galaxies: a challenge for cosmological simulations
José A. Benavides, Laura V. Sales, Julio F. Navarro +4
We study the prevalence of thin galaxies as a function of stellar mass in the range using data from the GAMA, DESI, ALFALFA, and Nearby…
The galaxy ultraviolet luminosity function from to in the COLIBRE simulations
Shengdong Lu, Carlos S. Frenk, Cedric G. Lacey +17
JWST has enabled the detection of galaxies in the earliest stages of cosmic history. We compare the ultraviolet luminosity functions (UVLFs) at redshifts predicted by the…
Galaxy luminosity functions from far-UV to submillimetre at in the COLIBRE simulations
Shengdong Lu, Carlos S. Frenk, Cedric G. Lacey +15
We present predictions from the recent COLIBRE cosmological hydrodynamical simulations of galaxy formation for the present-day galaxy luminosity functions (LFs) at wavelengths rang…
PAC in DESI. II. Galaxy-halo connection into the frontier
Kun Xu, Carlos S. Frenk, Y. P. Jing +40
Understanding dwarf galaxy formation is crucial for testing dark matter models and reionization physics. However, constructing stellar-mass complete spectroscopic samples at low ma…
