Surveying the Whirlpool at Arcseconds with NOEMA (SWAN)- I. Mapping the HCN and NH 3mm lines
Sophia K. Stuber, Jerome Pety, Eva Schinnerer +17
We present the first results from "Surveying the Whirlpool at Arcseconds with NOEMA" (SWAN), an IRAM Northern Extended Millimetre Array (NOEMA)+30m large program that maps emission…
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.…
A constant NH(1-0)-to-HCN(1-0) ratio on kiloparsec scales
M. J. Jiménez-Donaire, A. Usero, I. Bešlić +24
Nitrogen hydrides such as NH and NH are widely used by Galactic observers to trace the cold dense regions of the interstellar medium. In external galaxies, because of l…
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…
Spectral Stacking of Radio-Interferometric Data
Lukas Neumann, Jakob S. den Brok, Frank Bigiel +11
Mapping molecular line emission beyond the bright low-J CO transitions is still challenging in extragalactic studies, even with the latest generation of (sub-)mm interferometers, s…
The impact of HII regions on Giant Molecular Cloud properties in nearby galaxies sampled by PHANGS ALMA and MUSE
Antoine Zakardjian, Jérôme Pety, Cinthya N. Herrera +36
We identify giant molecular clouds (GMCs) associated with HII regions for a sample of 19 nearby galaxies using catalogs of GMCs and H regions released by the PHANGS-ALMA and PHANGS…
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…
Kinematic analysis of the super-extended HI disk of the nearby spiral galaxy M83
Cosima Eibensteiner, Frank Bigiel, Adam K. Leroy +33
We present new HI observations of the nearby massive spiral galaxy M83, taken with the VLA at angular resolution ( pc) of an extended (1.5 deg…
Wide-field CO isotopologue emission and the CO-to-H factor across the nearby spiral galaxy M101
Jakob S. den Brok, Frank Bigiel, Jérémy Chastenet +18
Carbon monoxide (CO) emission is the most widely used tracer of the bulk molecular gas in the interstellar medium (ISM) in extragalactic studies. The CO-to-H conversion factor,…
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…
Sub-kiloparsec empirical relations and excitation conditions of HCN and HCO+ J=3-2 in nearby star-forming galaxies
Axel Garcia-Rodriguez, Antonio Usero, Adam K. Leroy +24
We present new HCN and HCO (=3-2) images of the nearby star-forming galaxies (SFGs) NGC 3351, NGC 3627, and NGC 4321. The observations, obtained with the Morita ALMA Compact…
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,…
