PHANGS-JWST: the largest extragalactic molecular cloud catalog traced by polycyclic aromatic hydrocarbon emission
Z. Bazzi, D. Colombo, F. Bigiel +25
High-resolution JWST images of nearby spiral galaxies reveal polycyclic aromatic hydrocarbon (PAH) emission structures that trace molecular gas, including CO-dark regions. We ident…
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…
Surveying the Whirlpool at Arcseconds with NOEMA (SWAN): III. CO/CO ratio variations across the M51 galaxy
Ina Galić, Mallory Thorp, Frank Bigiel +16
CO isotopologues are common tracers of the bulk molecular gas in extragalactic studies, providing insights into the physical and chemical conditions of the cold molecular gas, a re…
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…
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).…
