The MALATANG survey: Dense gas distribution on sub-kiloparsec scales across the disk of M82
Jian-Fa Wang, Yu Gao, Qing-Hua Tan +23
We present observations of HCN J=4-3 and HCO^+ J=4-3 lines obtained with the James Clerk Maxwell Telescope as part of the MALATANG survey, combined with archival HCN J=1-0 and HCO^…
Does the HCN/CO ratio trace the star-forming fraction of gas? II. Variations in CO and HCN Emissivity
Ashley R. Bemis, Christine D. Wilson, Piyush Sharda +2
We model emissivities of the HCN and CO transitions using measured properties of clouds found in normal star forming galaxies and more extreme systems. These models are com…
Cloud-Scale Molecular Gas Properties of the Antennae Merger: A Comparative Study with PHANGS-ALMA Galaxies and NGC 3256
Nathan Brunetti, Christine D. Wilson, Hao He +8
We present observations of the central 9 kpc of the Antennae merger (NGC 4038/9) at 55 pc resolution in the CO 2-1 line obtained with the Atacama Large Millimeter/submillimeter Arr…
Physical Properties of Molecular Clouds in the Overlap Region of the Merging Antennae Galaxies
Grace Krahm, Molly K. Finn, Remy Indebetouw +3
As the closest major galaxy merger and home to thousands of super star clusters (SSCs), the Antennae Galaxies (NGC 4038 and NGC 4039) are an important location to study the molecul…
Unraveling the Mystery of the Low CO-to-H Conversion Factor in Starburst Galaxies: RADEX Modeling of the Antennae
Hao He, Christine D. Wilson, Jiayi Sun +3
CO emission has been widely used as a tracer of molecular gas mass. However, it is a long-standing issue to accurately constrain the CO-to-H conversion factor ($α_{\mathrm{CO}}…
Hydrodynamic simulations of the Disk of Gas Around Supermassive black holes (HDGAS) -I; Molecular Gas Dynamics
Mojtaba Raouf, Serena Viti, S. García-Burillo +9
We present hydrodynamic simulations of the interstellar medium (ISM) within the circumnuclear disk (CND) of a typical AGN-dominated galaxy influenced by mechanical feedback from an…
ATLASGAL: 3-mm class I methanol masers in high-mass star formation regions
W. Yang, Y. Gong, K. M. Menten +7
We analyzed the 3-mm wavelength spectral line survey of 408 ATLASGAL clumps observed with the IRAM 30m-telescope, focusing on the class I methanol masers with frequencies near 84,…
A nearly constant CN/HCN line ratio in nearby galaxies: CN as a new tracer of dense gas
Christine D. Wilson, Ashley Bemis, Blake Ledger +1
We investigate the relationship between CN N = 1 - 0 and HCN J = 1 - 0 emission on scales from 30 pc to 400 pc using ALMA archival data, for which CN is often observed simultaneous…
Does the HCN/CO ratio trace the star-forming fraction of gas? I. A comparison with analytical models of star formation
Ashley R. Bemis, Christine D. Wilson
We use archival ALMA observations of the HCN and CO transitions, in addition to the radio continuum at 93 GHz, to assess the relationship between dense gas, star formation,…
LoTSS Jellyfish Galaxies IV: Enhanced Star Formation on the Leading Half of Cluster Galaxies and Gas Compression in IC3949
Ian D. Roberts, Maojin Lang, Daria Trotsenko +7
With MaNGA integral field spectroscopy, we present a resolved analysis of star formation for 29 jellyfish galaxies in nearby clusters, identified from radio continuum imaging taken…
Embedded Young Massive Star Clusters in the Antennae Merger
Hao He, Christine Wilson, Nathan Brunetti +3
The properties of young massive clusters (YMCs) are key to understanding the star formation mechanism in starburst systems, especially mergers. We present ALMA high-resolution ($\s…
The Nearby Evolved Stars Survey II: Constructing a volume-limited sample and first results from the James Clerk Maxwell Telescope

The Nearby Evolved Stars Survey (NESS) is a volume-complete sample of 850 Galactic evolved stars within 3\,kpc at (sub-)mm wavelengths, observed in the CO (21) and…
Observed CN and HCN intensity ratios exhibit subtle variations in extreme galaxy environments
B. Ledger, C. D. Wilson, T. Michiyama +5
We use both new and archival ALMA data of three energy lines each of CN and HCN to explore intensity ratios in dense gas in NGC 3256, NGC 7469, and IRAS 13120-5453. The HCN (3-2)/H…
