Unveiling the population of massive quenched galaxies at in the COLIBRE simulations -- II. The role of AGN feedback and environment on their emergence

Ángel Chandro-Gómez, Claudia del P. Lagos, Chris Power +16

Early () Massive (), Quenched Galaxies (MQGs) challenge current galaxy formation models. In this series, we study these…

On the redshift evolution of the spin parameter in cosmological simulations

Tomas Riera, Alexander Knebe, Chris Power +2

Although the spin parameter of dark matter halos is well known to follow a log-normal distribution at fixed epoch, its quantitative redshift evolution - encompassing both the mean…

On bursty star formation during cosmological reionization -- influence on the metal and dust content of low-mass galaxies

Anand Menon, Sreedhar Balu, Chris Power

Observations indicate that high-redshift galaxies undergo episodic star formation bursts, driving strong outflows that expel gas and suppress accretion. We investigate the conseque…

The DORCHA suite: nature, nurture, and the phase space distribution of the Milky Way's high redshift progenitors today

Sreedhar Balu, Chris Power, Kris Walker +1

Where in the present-day Milky Way should we search for the remnants of its earliest stars? We address this question using the DORCHA (Gaelic for Dark; DUR-uh-khuh) suite: a set of…

On the Use of WGANs for Super-Resolution in Dark-Matter Simulations

John Brennan, Sreedhar Balu, Yuxiang Qin +2

Super-resolution techniques have the potential to reduce the computational cost of cosmological and astrophysical simulations. This can be achieved by enabling traditional simulati…
