xGASS: Total cold gas scaling relations and molecular-to-atomic gas ratios of galaxies in the local Universe
Barbara Catinella, Amélie Saintonge, Steven Janowiecki +10
We present the extended GALEX Arecibo SDSS Survey (xGASS), a gas fraction-limited census of the atomic (HI) gas content of 1179 galaxies selected only by stellar mass ($M_\star =10…
Lurking systematics in predicting galaxy cold gas masses using dust luminosities and star formation rates
Steven Janowiecki, Luca Cortese, Barbara Catinella +1
We use galaxies from the Herschel Reference Survey to evaluate commonly used indirect predictors of cold gas masses. We calibrate predictions for cold neutral atomic and molecular…
A multiwavelength survey of HI-excess galaxies with surprisingly inefficient star formation
K. Gereb, S. Janowiecki, B. Catinella +2
We present the results of a multiwavelength survey of HI-excess galaxies, an intriguing population with large HI reservoirs associated with little current star formation. These gal…
The Enigmatic (Almost) Dark Galaxy Coma P: The Atomic Interstellar Medium
Catherine Ball, John M. Cannon, Lukas Leisman +12
We present new high-resolution HI spectral line imaging of Coma P, the brightest HI source in the system HI 123220. This extremely low surface brightness galaxy was first identi…
Metal Abundances of KISS Galaxies. VI. New Metallicity Relations for the KISS Sample of Star-Forming Galaxies
Alec S. Hirschauer, John J. Salzer, Steven Janowiecki +1
We present updated metallicity relations for the spectral database of star-forming galaxies (SFGs) found in the KPNO International Spectroscopic Survey (KISS). New spectral observa…
