If dark matter is fuzzy, the first stars form in massive pancakes

Mihir Kulkarni, Eli Visbal, Greg L. Bryan +1

Fuzzy dark matter (FDM) is a proposed modification for the standard cold dark matter (CDM) model motivated by small-scale discrepancies in low-mass galaxies. Composed of ultra-ligh…

The observable properties of galaxy accretion events in Milky Way-like galaxies in the FIRE-2 cosmological simulations

Danny Horta, Emily C. Cunningham, Robyn E. Sanderson +7

In the -Cold Dark Matter model of the Universe, galaxies form in part through accreting satellite systems. Previous work have built an understanding of the signatures of these p…

Regulation of Star Formation by a Hot Circumgalactic Medium

Christopher Carr, Greg L. Bryan, Drummond B. Fielding +2

Galactic outflows driven by supernovae (SNe) are thought to be a powerful regulator of a galaxy's star-forming efficiency. Mass, energy, and metal outflows (, , and …
