The frequency of very young galaxies in the local Universe: II. The view from SDSS spectra
Gary A. Mamon, Marina Trevisan, Trinh X. Thuan +2
Only a handful of galaxies in the local Universe appear to be very young. We estimate the fraction of very young galaxies (VYGs), defined as those with more than half their stellar…
Photometric properties of reionization-epoch galaxies in the Simba simulations
Xiaohan Wu, Romeel Davé, Sandro Tacchella +1
We study the photometric properties and sizes of the reionization-epoch galaxies in high-resolution Simba cosmological hydrodynamical simulations with box sizes of …
The impact of quenching on galaxy profiles in the Simba simulation
Sarah Appleby, Romeel Davé, Katarina Kraljic +2
We study specific star formation rate (sSFR) and gas profiles of star forming and green valley galaxies in the Simba cosmological hydrodynamic simulation. Star-forming galaxy half-…
Jet Feedback and the Photon Underproduction Crisis in Simba
Jacob F. Christiansen, Romeel Davé, Daniele Sorini +1
We examine the impact of black hole jet feedback on the properties of the low-redshift intergalactic medium (IGM) in the SIMBA simulation, with a focus on the Ly forest mean flu…
The impact of the connectivity of the cosmic web on the physical properties of galaxies at its nodes
Katarina Kraljic, Christophe Pichon, Sandrine Codis +11
We investigate the impact of the number of filaments connected to the nodes of the cosmic web on the physical properties of their galaxies using the Sloan Digital Sky Survey. We co…
The Impact of Wind Scalings on Stellar Growth and the Baryon Cycle in Cosmological Simulations
Shuiyao Huang, Neal Katz, Romeel Davé +5
Many phenomenologically successful cosmological galaxy formation simulations employ kinetic winds to model galactic outflows, a crucial ingredient in obtaining predictions that agr…
