The PHANGS-HST-Halpha Survey: Warm Ionized Gas Physics at High Angular resolution in Nearby GalaxieS with the Hubble Space Telescope
Rupali Chandar, Ashley T. Barnes, David A. Thilker +36
The PHANGS project is assembling a comprehensive, multi-wavelength dataset of nearby (~5-20 Mpc), massive star-forming galaxies to enable multi-phase, multi-scale investigations in…
The ALMOND Survey: Molecular cloud properties and gas density tracers across 25 nearby spiral galaxies with ALMA
Lukas Neumann, Molly J. Gallagher, Frank Bigiel +28
We use new HCN(1-0) data from the ALMOND (ACA Large-sample Mapping Of Nearby galaxies in Dense gas) survey to trace the kpc-scale molecular gas density structure and CO(2-1) data f…
Dependence of on metallicity, intensity, and spatial scale in a self-regulated interstellar medium
Chia-Yu Hu, Andreas Schruba, Amiel Sternberg +1
We study the CO(1-0)-to-H conversion factor () and the line ratio of CO(2-1)-to-CO(1-0) () across a wide range of metallicity ()…
Molecular Gas Properties and CO-to-H2 Conversion Factors in the Central Kiloparsec of NGC 3351
Yu-Hsuan Teng, Karin M. Sandstrom, Jiayi Sun +16
The CO-to-H conversion factor ($α_\rm{CO}$) is critical to studying molecular gas and star formation in galaxies. The value of $α_\rm{CO}$ has been found to vary within and bet…
Physical Properties of Molecular Clouds at 2 parsec Resolution in the Low-Metallicity Dwarf Galaxy NGC 6822 and the Milky Way
Andreas Schruba, Adam K. Leroy, J. M. Diederik Kruijssen +6
We present the ALMA survey of CO(2-1) emission from the 1/5 solar metallicity, Local Group dwarf galaxy NGC 6822. We achieve high (0.9 arcsec ~ 2 pc) spatial resolution while cover…
CO/CO Gradients Across the Disks of Nearby Spiral Galaxies
M. J. Jimenez-Donaire, D. Cormier, F. Bigiel +14
We use the IRAM Large Program EMPIRE and new high-resolution ALMA data to measure 13CO(1-0)/C18O(1-0) intensity ratios across nine nearby spiral galaxies. These isotopologues of CO…
