Resolved low-J CO excitation at 190 parsec resolution across NGC 2903 and NGC 3627

J. S. den Brok, A. K. Leroy, A. Usero +14

The low- rotational transitions of CO are commonly used to trace the distribution of molecular gas in galaxies. Their ratios are sensitive to excitation and physical cond…

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…

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…

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…

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…
