Stored in the archives: Uncovering the CN/CO intensity ratio with ALMA in nearby U/LIRGs
Blake Ledger, Toshiki Saito, Daisuke Iono +1
We present an archival Atacama Large Millimeter/submillimeter Array (ALMA) study of the CN N = 1 - 0 / CO J = 1 - 0 intensity ratio in nearby (z < 0.05) Ultra Luminous and Luminous…
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.…
J0107a: A Barred Spiral Dusty Star-forming Galaxy at
Shuo Huang, Ryohei Kawabe, Kotaro Kohno +7
Dusty Star-Forming Galaxies (DSFGs) are amongst the most massive and active star-forming galaxies during the cosmic noon. Theoretical studies have proposed various formation mechan…
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…
Molecular Abundance of the Circumnuclear Region Surrounding an Active Galactic Nucleus in NGC 1068 based on Imaging Line Survey in the 3-mm Band with ALMA
Taku Nakajima, Shuro Takano, Tomoka Tosaki +9
We present an imaging molecular line survey in the 3-mm band (85-114 GHz) focused on one of the nearest galaxies with an active galactic nucleus (AGN), NGC 1068, based on observati…
The Gas Morphology of Nearby Star-Forming Galaxies
S. K. Stuber, E. Schinnerer, T. G. Williams +22
The morphology of a galaxy stems from secular and environmental processes during its evolutionary history. Thus galaxy morphologies have been a long used tool to gain insights on g…
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…
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…
ALMA Detection of 321 GHz water maser emission in the radio galaxy NGC 1052
Seiji Kameno, Yuichi Harikane, Satoko Sawada-Satoh +4
The Atacama Large Millimeter/submillimeter Array (ALMA) serendipitously detected HO emission at 321 GHz in NGC 1052. This is the first submill…
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,…
Quantifying the energetics of molecular superbubbles in PHANGS galaxies
E. J. Watkins, K. Kreckel, B. Groves +26
Star formation and stellar feedback are interlinked processes that redistribute energy and matter throughout galaxies. When young, massive stars form in spatially clustered environ…
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,…
