The Spatial Relation between Young Star Clusters and Molecular Clouds in M 51 with LEGUS
K. Grasha, D. Calzetti, A. Adamo +21
We present a study correlating the spatial locations of young star clusters with those of molecular clouds in NGC~5194, in order to investigate the timescale over which clusters se…
Do Spectroscopic Dense Gas Fractions Track Molecular Cloud Surface Densities?
Molly J. Gallagher, Adam K. Leroy, Frank Bigiel +22
We use ALMA and IRAM 30-m telescope data to investigate the relationship between the spectroscopically-traced dense gas fraction and the cloud-scale (120 pc) molecular gas surface…
Azimuthal variations of gas-phase oxygen abundance in NGC 2997
I-Ting Ho, Sharon E. Meidt, Rolf-Peter Kudritzki +7
The azimuthal variation of the HII region oxygen abundance in spiral galaxies is a key observable for understanding how quickly oxygen produced by massive stars can be dispersed wi…
Cloud-Scale Molecular Gas Properties in 15 Nearby Galaxies
Jiayi Sun, Adam K. Leroy, Andreas Schruba +16
We measure the velocity dispersion, , and surface density, , of the molecular gas in nearby galaxies from CO spectral line cubes with spatial resolution - pc, matche…
Dense Gas, Dynamical Equilibrium Pressure, and Star Formation in Nearby Star-Forming Galaxies
Molly J. Gallagher, Adam K. Leroy, Frank Bigiel +17
We use new ALMA observations to investigate the connection between dense gas fraction, star formation rate, and local environment across the inner region of four local galaxies sho…
