Dark-ages Reionization and Galaxy Formation Simulation - XIV. Gas accretion, cooling and star formation in dwarf galaxies at high redshift
Yuxiang Qin, Alan R. Duffy, Simon J. Mutch +4
We study dwarf galaxy formation at high redshift () using a suite of high- resolution, cosmological hydrodynamic simulations and a semi-analytic model (SAM). We focus on gas…
A First Transients Survey with JWST: the FLARE project
Lifan Wang, D. Baade, E. Baron +43
JWST was conceived and built to answer one of the most fundamental questions that humans can address empirically: "How did the Universe make its first stars?". Our First Lights At…
Dark-ages Reionization and Galaxy Formation Simulation - XIII. AGN quenching of high-redshift star formation in ZF-COSMOS-20115
Yuxiang Qin, Simon J. Mutch, Alan R. Duffy +4
Massive quiescent galaxies (MQGs) are thought to have formed stars rapidly at early times followed by a long period of quiescence. The recent discovery of a MQG, ZF-COSMOS-20115 at…
