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,…
The HST-Hyperion Survey: Environmental Imprints on the Stellar-Mass Function at z~2.5
Derek Sikorski, Ben Forrest, Brian C. Lemaux +19
Not all galaxies at Cosmic Noon evolve in the same way. It remains unclear how the local environment -- especially the extreme overdensities of protoclusters -- affects stellar mas…
The HST-Hyperion Survey: Companion Fraction and Overdensity in a z ~ 2.5 Proto-supercluster
F. Giddings, B. C. Lemaux, B. Forrest +22
We present a study of the galaxy merger and interaction activity within the Hyperion Proto-supercluster at z~2.5 in an effort to assess the occurrence of galaxy mergers and interac…
Gas properties as a function of environment in the proto-supercluster Hyperion at z ~ 2.45
G. Gururajan, O. Cucciati, B. C. Lemaux +26
The cosmic star-formation rate density, molecular gas density and the AGN activity of the Universe peak at z~ 2-3, showing the Universe is most active at this epoch. The nature of…
