Igniting Galaxy Formation in the Postreionization Universe, II: Nature versus Nurture
Jorge Moreno, Defne Aluç, Eisha López +7
Although the ultraviolet background from reionization is thought to conspire against the smallest halos, some gas-rich halos in the post-reionization Universe still form stars. We…

The quenched fraction of satellites around simulated Milky Way-mass galaxies
Francisco J. Mercado, Devontae C. Baxter, M. Katy Rodriguez Wimberly +7
We compare satellite quenched fractions across three cosmological simulation suites (FIREbox, the FIRE-2 zoom-ins, and IllustrisTNG50) and observational datasets from SAGA, ELVES,…
