Resolved Measurements of the CO-to-H Conversion Factor in 37 Nearby Galaxies
I-Da Chiang, Karin M. Sandstrom, Jeremy Chastenet +6
We measure the CO-to-H conversion factor () in 37 galaxies at 2~kpc resolution, using dust surface density inferred from far-infrared emission as a tracer of the…
The PHANGS-AstroSat Atlas of Nearby Star Forming Galaxies
Hamid Hassani, Erik Rosolowsky, Eric W. Koch +29
We present the Physics at High Angular resolution in Nearby GalaxieS (PHANGS)-AstroSat atlas, which contains ultraviolet imaging of 31 nearby star-forming galaxies captured by the…
A Two-Component Probability Distribution Function Describes the mid-IR Emission from the Disks of Star-Forming Galaxies
Debosmita Pathak, Adam K. Leroy, Todd A. Thompson +28
High-resolution JWST-MIRI images of nearby spiral galaxies reveal emission with complex substructures that trace dust heated both by massive young stars and the diffuse interstella…
Star Formation Efficiency in Nearby Galaxies Revealed with a New CO-to-H2 Conversion Factor Prescription
Yu-Hsuan Teng, I-Da Chiang, Karin M. Sandstrom +24
Determining how galactic environment, especially the high gas densities and complex dynamics in bar-fed galaxy centers, alters the star formation efficiency (SFE) of molecular gas…
A sensitive, high-resolution, wide-field IRAM NOEMA CO(1-0) survey of the very nearby spiral galaxy IC 342
M. Querejeta, J. Pety, A. Schruba +31
We present a new wide-field 10.75 x 10.75 arcmin^2 (~11x11 kpc^2), high-resolution (theta = 3.6" ~ 60 pc) NOEMA CO(1-0) survey of the very nearby (d=3.45 Mpc) spiral galaxy IC 342.…
Resolved Kennicutt-Schmidt law in two strongly lensed star-forming galaxies at redshift 1
David Nagy, Miroslava Dessauges-Zavadsky, Matteo Messa +4
We study the star formation rate (SFR) versus molecular gas mass () scaling relation from hundreds to thousands parsec scales in two strongly lensed galaxies at red…
Calibrating mid-infrared emission as a tracer of obscured star formation on HII-region scales in the era of JWST
Francesco Belfiore, Adam K. Leroy, Thomas G. Williams +25
Measurements of the star formation activity on cloud scales are fundamental to uncovering the physics of the molecular cloud, star formation, and stellar feedback cycle in galaxies…
Fuelling the nuclear ring of NGC 1097
Mattia C. Sormani, Ashley T. Barnes, Jiayi Sun +24
Galactic bars can drive cold gas inflows towards the centres of galaxies. The gas transport happens primarily through the so-called bar ``dust lanes'', which connect the galactic d…
The Physical Drivers and Observational Tracers of CO-to-H2 Conversion Factor Variations in Nearby Barred Galaxy Centers
Yu-Hsuan Teng, Karin M. Sandstrom, Jiayi Sun +24
The CO-to-H conversion factor ($α_\rm{CO}$) is central to measuring the amount and properties of molecular gas. It is known to vary with environmental conditions, and previous…
Star Formation Laws and Efficiencies across 80 Nearby Galaxies
Jiayi Sun, Adam K. Leroy, Eve C. Ostriker +37
We measure empirical relationships between the local star formation rate (SFR) and properties of the star-forming molecular gas on 1.5 kpc scales across 80 nearby galaxies. These r…
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…
Kpc-scale properties of dust temperature in terms of dust mass and star formation activity
I-Da Chiang, Hiroyuki Hirashita, Jeremy Chastenet +7
We investigate how the dust temperature is affected by local environmental quantities, especially dust surface density (), dust-to-gas ratio (D/G) and interstellar…
PHANGS-JWST First Results: Mid-infrared emission traces both gas column density and heating at 100 pc scales
Adam K. Leroy, Karin Sandstrom, Erik Rosolowsky +48
We compare mid-infrared (mid-IR), extinction-corrected H, and CO (2-1) emission at 70--160 pc resolution in the first four PHANGS-JWST targets. We report correlation strengths,…
