The EDGE-CALIFA survey: exploring the role of the molecular gas on the galaxy star formation quenching
D. Colombo, S. F. Sanchez, A. D. Bolatto +11
Understanding how galaxies cease to form stars represents an outstanding challenge for galaxy evolution theories. This process of "star formation quenching" has been related to var…
The EDGE-CALIFA Survey: Using Optical Extinction to Probe the Spatially-Resolved Distribution of Gas in Nearby Galaxies

We present an empirical relation between the cold gas surface density () and the optical extinction () in a sample of 103 galaxies from the Extragalactic Da…
The Dark Matter Distributions in Low-Mass Disk Galaxies. II. The Inner Density Profiles
Nicole C. Relatores, Andrew B. Newman, Joshua D. Simon +8
Dark matter-only simulations predict that dark matter halos have steep, cuspy inner density profiles, while observations of dwarf galaxies find a range of inner slopes that are oft…
The EDGE-CALIFA Survey: Exploring the Star Formation Law through Variable Selection
Biprateep Dey, Erik Rosolowsky, Yixian Cao +10
We present a multilinear analysis to determine the significant predictors of star formation in galaxies using the combined EDGE-CALIFA sample of galaxies. We analyze 1845 kpc-scale…
Antlia2's role in driving the ripples in the outer gas disk of the Galaxy
Sukanya Chakrabarti, Philip Chang, Adrian Price-Whelan +3
We employ the earlier published proper motions of the newly discovered Antlia 2 dwarf galaxy derived from Gaia data to calculate its orbital distribution in the cosmologically rece…
The EDGE-CALIFA Survey: Evidence for Pervasive Extraplanar Diffuse Ionized Gas in Nearby Edge-On Galaxies
Rebecca C. Levy, Alberto D. Bolatto, Sebastián F. Sánchez +9
We investigate the prevalence, properties, and kinematics of extraplanar diffuse ionized gas (eDIG) in a sample of 25 edge-on galaxies selected from the CALIFA survey. We measure i…
