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.…
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…
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,…
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…
