Probing the CGM of Low-redshift Dwarf Galaxies Using FIRE Simulations
Fei Li, Mubdi Rahman, Norman Murray +7
Observations of UV metal absorption lines have provided insight into the structure and composition of the circumgalactic medium (CGM) around galaxies. We compare these observations…
A Relationship Between Stellar Metallicity Gradients and Galaxy Age in Dwarf Galaxies
Francisco J. Mercado, James S. Bullock, Michael Boylan-Kolchin +7
We explore the origin of stellar metallicity gradients in simulated and observed dwarf galaxies. We use FIRE-2 cosmological baryonic zoom-in simulations of 26 isolated galaxies as…
Data-driven spectroscopic estimates of absolute magnitude, distance and binarity -- method and catalog of 16,002 O- and B-type stars from LAMOST
Mao-Sheng Xiang, Hans-Walter Rix, Yuan-Sen Ting +4
We present a data-driven method to estimate absolute magnitudes for O- and B-type stars from the LAMOST spectra, which we combine with {\it Gaia} parallaxes to infer distance and b…
The time-scales probed by star formation rate indicators for realistic, bursty star formation histories from the FIRE simulations
José A. Flores Velázquez, Alexander B. Gurvich, Claude-André Faucher-Giguère +10
Understanding the rate at which stars form is central to studies of galaxy formation. Observationally, the star formation rates (SFRs) of galaxies are measured using the luminosity…
Spatial and Kinematic Clustering of Stars in the Galactic Disk
Harshil Kamdar, Charlie Conroy, Yuan-Sen Ting +1
The Galactic disk is expected to be spatially, kinematically, and chemically clustered on many scales due to both star formation and non-axisymmetries in the Galactic potential. In…
Virialization of the inner CGM in the FIRE simulations and implications for galaxy discs, star formation and feedback
Jonathan Stern, Claude-André Faucher-Giguère, Drummond Fielding +13
We use the FIRE-2 cosmological simulations to study the formation of a quasi-static, virial-temperature gas phase in the circumgalactic medium (CGM) at redshifts 0<z<5, and how the…
