VERTICO III: The Kennicutt-Schmidt relation in Virgo cluster galaxies
M. J. Jiménez-Donaire, T. Brown, C. D. Wilson +19
In this VERTICO science paper we aim to study how the star formation process depends on galactic environment and gravitational interactions in the context of galaxy evolution. We e…
VERTICO IV: Environmental Effects on the Gas Distribution and Star Formation Efficiency of Virgo Cluster Spirals
Vicente Villanueva, Alberto D. Bolatto, Stuart Vogel +18
We measure the molecular-to-atomic gas ratio, , and the star formation rate (SFR) per unit molecular gas mass, SFE, in 38 nearby galaxies selected from the…
Low-J CO Line Ratios From Single Dish CO Mapping Surveys and PHANGS-ALMA
Adam K. Leroy, Erik Rosolowsky, Antonio Usero +32
We measure the low-J CO line ratio R21=CO(2-1)/CO(1-0), R32=CO(3-2)/CO(2-1), and R31 = CO(3-2)/CO(1-0) using whole-disk CO maps of nearby galaxies. We draw CO(2-1) from PHANGS--ALM…
Super Star Clusters in the Central Starburst of NGC 4945
Kimberly L. Emig, Alberto D. Bolatto, Adam K. Leroy +12
NGC 4945 is a nearby (3.8 Mpc) galaxy hosting a nuclear starburst and Seyfert Type 2 AGN. We use the Atacama Large Millimeter/submillimeter Array (ALMA) to image the 93 GHz (3.2 mm…
Molecular Gas Properties on Cloud Scales Across the Local Star-forming Galaxy Population
Jiayi Sun, Adam K. Leroy, Eva Schinnerer +34
Using the PHANGS-ALMA CO (2-1) survey, we characterize molecular gas properties on 100 pc scales across 102,778 independent sightlines in 70 nearby galaxies. This yields th…
Optical Depth Estimates and Effective Critical Densities of Dense Gas Tracers in the Inner Parts of Nearby Galaxy Discs
M. J. Jimenez-Donaire, F. Bigiel, A. K. Leroy +17
High critical density molecular lines like HCN(1-0) or HCO+(1-0) represent our best tool to study currently star-forming, dense molecular gas at extragalactic distances. The optica…
Millimeter-Wave Line Ratios and Sub-beam Volume Density Distributions
Adam K. Leroy, Antonio Usero, Andreas Schruba +11
We explore the use of mm-wave emission line ratios to trace molecular gas density when observations integrate over a wide range of volume densities within a single telescope beam.…
