N., Kuno, Nario, Madore, Barry F., Martín, Sergio, Meyer, Jennifer Donovan, Muraoka, Kazuyuki, Watanabe, Yoshimasa

We present a catalog of clouds identified from the $^{12}$CO (1--0) data of M83, which was observed using Atacama Large Millimeter/submillimeter Array (ALMA) with a spatial resolution of $\sim$46 pc and a mass sensitivity of $\sim$10$^4$ $M_{\odot}$

The Local Group L-Band Survey: The First Measurements of Localized Cold Neutral Medium Properties in the Low-Metallicity Dwarf Galaxy NGC 6822

Autor: Pingel, Nickolas M., Chen, Hongxing, Stanimirović, Snežana, Koch, Eric W., Leroy, Adam K., Rosolowsky, Erik, Kim, Chang-Goo, Dalcanton, Julianne J., Walter, Fabian, Busch, Michael P., Chown, Ryan, Meyer, Jennifer Donovan, Eibensteiner, Cosima, Hunter, Deidre A., Sarbadhicary, Sumit K., Tarantino, Elizabeth, Villanueva, Vicente, Williams, Thomas G.

Measuring the properties of the cold neutral medium (CNM) in low-metallicity galaxies provides insight into heating and cooling mechanisms in early Universe-like environments. We report detections of two localized atomic neutral hydrogen (HI) absorpt

Most low-mass stars form in stellar clusters that also contain massive stars, which are sources of far-ultraviolet (FUV) radiation. Theoretical models predict that this FUV radiation produces photo-dissociation regions (PDRs) on the surfaces of proto

We present a comparative study of the molecular gas in two galaxies from the LEGUS sample: barred spiral NGC 1313 and flocculent spiral NGC 7793. These two galaxies have similar masses, metallicities, and star formation rates, but NGC 1313 is forming

Star formation in galaxies is regulated by turbulence, outflows, gas heating and cloud dispersal -- processes which depend sensitively on the properties of the interstellar medium (ISM) into which supernovae (SNe) explode. Unfortunately, direct measu
