Azimuthal offsets in spiral arms of nearby galaxies

Miguel Querejeta, Sharon E. Meidt, Yixian Cao +28

Spiral arms play a central role in disc galaxies, but their dynamical nature remains a long-standing open question. Azimuthal offsets between molecular gas and star formation are e…

The SWAN view of dense gas in the Whirlpool -- A cloud-scale comparison of N2H+, HCO+, HNC and HCN emission in M51

Sophia K. Stuber, Eva Schinnerer, Antonio Usero +22

Tracing dense molecular gas, the fuel for star formation, is essential for the understanding of the evolution of molecular clouds and star formation processes. We compare the emiss…

Constraining resolved extragalactic variation with well calibrated ALMA observations

Jakob den Brok, Elias K. Oakes, Adam K. Leroy +13

CO(1-0) and CO(2-1) are commonly used as bulk molecular gas tracers. The CO line ratios (especially CO(2-1)/CO(1-0) - ) vary within and among galaxies, yet previous studies…

The resolved star-formation efficiency of early-type galaxies

Thomas G. Williams, Francesco Belfiore, Martin Bureau +19

Understanding how and why star formation varies between galaxies is fundamental to our comprehension of galaxy evolution. In particular, the star-formation efficiency (SFE; star-fo…

From Non-Detection to Detection: Atacama Compact Array Mosaic Observations of Faint Extended [C I] Emission in NGC 7679

Tomonari Michiyama, Toshiki Saito, Kouichiro Nakanishi +8

We report the detection of [C I] -- emission in the nearby galaxy NGC 7679 using the Atacama Compact Array (ACA) of the Atacama Large Millimeter/submillimeter Array (…

Surveying the Whirlpool at Arcseconds with NOEMA (SWAN) II: Survey design and observations

K. Sophia Stuber, Jerome Pety, Antonio Usero +18

We present Surveying the Whirlpool at Arcseconds with NOEMA (SWAN), a high-resolution, high-sensitivity survey to map molecular lines in the 3mm band in M51 (the Whirlpool galaxy).…

Cloud-scale gas properties, depletion times, and star formation efficiency per free-fall time in PHANGS--ALMA

Adam K. Leroy, Jiayi Sun, Sharon Meidt +31

We compare measurements of star formation efficiency to cloud-scale gas properties across PHANGS-ALMA. Dividing 67 galaxies into 1.5 kpc scale regions, we calculate the molecular g…
