The HII Regions' Molecular Law of Star Formation
Daniela Calzetti, Drew Lapeer, Robert C. Kennicutt +28
We combine imaging data from the HST, JWST, and ground-based millimeter facilities to investigate the correlation between star formation rate (SFR) and molecular gas at the ~100 pc…
Dust-Embedded Star Formation: Bridging Magellanic Cloud Studies of Massive Young Stellar Objects to Nearby Spiral Galaxies
M. Jimena RodrÃguez, Rémy Indebetouw, Janice C. Lee +13
We use JWST NIRCam and MIRI imaging at 2, 4, 10, and 21 um to study young, dusty compact sources in four nearby galaxies at distances of ~ 1-5Mpc (M33, NGC300, NGC7793, and NGC5068…
The emerging timescale of young star clusters regulated by cluster stellar mass
Alex Pedrini, Angela Adamo, Daniela Calzetti +23
Quantifying the timescales of star cluster emergence from their natal clouds remains one of the main challenges in understanding the star formation process. These timescales are fu…
Ultra-deep imaging of nearby dwarf irregular galaxies: stellar haloes and disk structure
Deidre A. Hunter, Bruce G. Elmegreen
We have examined the stellar structure of 10 nearby, low stellar mass (10^6 to 6 x 10^7 Msolar) dwarf irregular galaxies by fitting ellipses as a function of surface brightness on…
Pervasive Cavity-Ring Structure for Star Formation in Dwarf Irregular Galaxies
Bruce G. Elmegreen, Deidre A. Hunter
Unsharp-mask images of HI emission from 36 dwarf irregular (dIrr) galaxies illustrate star formation in dispersed clouds and on the rims of large cavities. The cavities can extend…
Galaxy UV Legacy Project: Survey Description and First Insights Into NGC 4449 Recent History of Star Formation
E. Sabbi, B. Meena, P. Zeidler +18
The Galaxy UV Legacy Project (GULP) is a Cycle 28 Treasury program with the Hubble Space Telescope (HST) designed to characterize resolved massive stars, OB associations, and young…
