The Neutral Hydrogen Properties of Galaxies in Gas-rich Groups
Robert Džudžar, Virginia Kilborn, Gerhardt Meurer +23
We present an analysis of the integrated neutral hydrogen (HI) properties for 27 galaxies within nine low mass, gas-rich, late-type dominated groups which we denote "Choirs". We fi…
Anomalously low metallicity regions in MaNGA star-forming galaxies: Accretion Caught in Action?
Hsiang-Chih Hwang, Jorge K. Barrera-Ballesteros, Timothy M. Heckman +14
We use data from 1222 late-type star-forming galaxies in the SDSS IV MaNGA survey to identify regions in which the gas-phase metallicity is anomalously-low compared to expectations…
Discovery of a Damped Ly-alpha System in a Low-z Galaxy Group: Possible Evidence for Gas Inflow and Nuclear Star Formation
Sanchayeeta Borthakur, Emmanuel Momjian, Timothy M. Heckman +3
We present a low-redshift (z=0.029) Damped Lyman-alpha (DLA) system in the spectrum of a background Quasi-Stellar Object (QSO). The DLA is associated with an interacting galaxy pai…
Detecting Radio-AGN signatures in Red geysers
Namrata Roy, Kevin Bundy, Edmond Cheung +19
A new class of quiescent galaxies harboring possible AGN-driven winds has been discovered using spatially resolved optical spectroscopy from the ongoing SDSS-IV MaNGA survey. These…
SDSS-IV MaNGA: Spatially resolved star-formation histories and the connection to galaxy physical properties
K. Rowlands, T. Heckman, V. Wild +11
A key task of observational extragalactic astronomy is to determine where -- within galaxies of diverse masses and morphologies -- stellar mass growth occurs, how it depends on gal…
Near-identical star formation rate densities from H and FUV at redshift zero
Fiona M. Audcent-Ross, Gerhardt R. Meurer, O. I. Wong +27
For the first time both H and far-ultraviolet (FUV) observations from an HI-selected sample are used to determine the dust-corrected star formation rate density (SFRD: )…
