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…
An uncertainty principle for star formation - IV. On the nature and filtering of diffuse emission
Alexander P. S. Hygate, J. M. Diederik Kruijssen, Mélanie Chevance +3
Diffuse emission is observed in galaxies in many tracers across the electromagnetic spectrum, including tracers of star formation, such as H and ultraviolet (UV), and tracers of…
An uncertainty principle for star formation -- III. The characteristic emission time-scales of star formation rate tracers
Daniel T. Haydon, J. M. Diederik Kruijssen, Mélanie Chevance +4
We recently presented a new statistical method to constrain the physics of star formation and feedback on the cloud scale by reconstructing the underlying evolutionary timeline. Ho…
A 50 pc scale view of star formation efficiency across NGC 628
K. Kreckel, C. Faesi, J. M. D. Kruijssen +16
Star formation is a multi-scale process that requires tracing cloud formation and stellar feedback within the local (<kpc) and global galaxy environment. We present first results f…
The Star Formation Efficiency per Free Fall Time in Nearby Galaxies
Dyas Utomo, Jiayi Sun, Adam K. Leroy +16
We estimate the star formation efficiency per gravitational free fall time, , from observations of nearby galaxies with resolution matched to the typical size of a Gian…
Dense Molecular Gas in the Nearby Low Metallicity Dwarf Starburst Galaxy IC 10
Amanda A. Kepley, Lauren Bittle, Adam K. Leroy +6
Dense molecular gas and star formation are correlated in galaxies. The effect of low metallicity on this relationship is crucial for interpreting observations of high redshift gala…
Kinematics of the Atomic ISM in M33 on 80 pc scales
Eric W. Koch, Erik W. Rosolowsky, Felix J. Lockman +7
We present new L-band ($1\mbox{--}2$ GHz) observations of the nearby spiral galaxy M33 with 80 pc resolution obtained with the Karl G. Jansky Very Large Array. The HI observations,…
The Metallicity Dependence of the HI Shielding Layers in Nearby Galaxies
Andreas Schruba, Shmuel Bialy, Amiel Sternberg
We investigate the metallicity dependence of HI surface densities in star-forming regions along many lines of sight within 70 nearby galaxies, probing kpc to 50 pc scales. We emplo…
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…
An uncertainty principle for star formation - II. A new method for characterising the cloud-scale physics of star formation and feedback across cosmic history
J. M. Diederik Kruijssen, Andreas Schruba, Alexander P. S. Hygate +3
The cloud-scale physics of star formation and feedback represent the main uncertainty in galaxy formation studies. Progress is hampered by the limited empirical constraints outside…
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…
Full-disc CO(1-0) mapping across nearby galaxies of the EMPIRE survey and the CO-to-H conversion factor
D. Cormier, F. Bigiel, M. J. Jiménez-Donaire +16
Carbon monoxide (CO) provides crucial information about the molecular gas properties of galaxies. While CO has been targeted extensively, isotopologues such as CO hav…
