IQ Collaboratory II: The Quiescent Fraction of Isolated, Low Mass Galaxies Across Simulations and Observations
Claire M Dickey, Tjitske K Starkenburg, Marla Geha +10
We compare three major large-scale hydrodynamical galaxy simulations (EAGLE, Illustris-TNG, and SIMBA) by forward modeling simulated galaxies into observational space and computing…
Populating the low-mass end of the relation
Vivienne F. Baldassare, Claire Dickey, Marla Geha +1
We present high resolution spectroscopy taken with the Keck Echellete Spectrograph and Imager to measure stellar velocity dispersions for eight active dwarf galaxies ($M_{\ast}<3\t…
AGN All the Way Down? AGN-like Line Ratios are Common In the Lowest-Mass Isolated Quiescent Galaxies
C. Dickey, M. Geha, A. Wetzel +1
We investigate the lowest-mass quiescent galaxies known to exist in isolated environments (; 1.5 Mpc from a more massive galaxy). This popula…
IQ-Collaboratory 1.1: the Star-Forming Sequence of Simulated Central Galaxies
ChangHoon Hahn, Tjitske K. Starkenburg, Ena Choi +12
A tightly correlated star formation rate-stellar mass relation of star forming galaxies, or star-forming sequence (SFS), is a key feature in galaxy property-space that is predicted…
The Effect of AGN on the Global HI Content of Isolated Low-Mass Galaxies
Jeremy D. Bradford, Marla C. Geha, Jenny E. Greene +2
We investigate the global neutral hydrogen (HI) content of isolated galaxies selected from the SDSS spectroscopic survey with optical evidence of Active Galactic Nuclei (AGN). Our…
