Ionized Gas Kinematics and Star-forming Clumps in Extremely Metal-poor Galaxies
Jyoti Yadav, Casiana Muñoz Tuñón, Cecilia Farina +3
Extremely Metal Poor (XMP) galaxies are the least chemically evolved objects in the local Universe and provide important constraints on galaxy formation in low-metallicity environm…
Metal-poor molecular clouds in dwarf galaxies at parsec-scale resolution
L. K. Hunt, M. Heyer, U. Lisenfeld +17
Understanding how stars form at low metallicity is challenging because carbon monoxide (CO) emission, which usually probes the molecular gas reservoir, is faint, and tends to be co…
Tracking the flow of interstellar gas across scales: from galaxies to star clusters
Ana Duarte-Cabral, Maxime Valeille-Manet, Mathilde Bouvier +30
While the baryon cycle of the interstellar medium - and its ability to form stars - plays a key role in galaxy evolution, unravelling the physical processes driving its evolution r…
The kinematics of tadpole galaxies at intermediate redshift
Manish Kataria, Kanak Saha, Bruce Elmegreen
Galaxy morphology and kinematics encode complementary information about the assembly history of galaxies, but the extent to which they evolve in tandem remains unclear. Tadpole gal…
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

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…
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…
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…
Scattering, Migration, Re-circularization and Relaxation to Build Out Galaxy Disks with Exponential Profiles
Curtis Struck, Bruce G. Elmegreen, Elena DOnghia
Scattering of stars by interstellar clouds or massive clumps increases the stellar velocity dispersion and promotes a radial disk profile that is exponential. Here we show that suc…
FEAST: Probing Hierarchical Star Formation with the Spatial Distributions of Young Star Clusters
Drew Lapeer, Daniela Calzetti, Kathryn Grasha +19
We apply the angular two-point correlation function (TPCF) to the spatial distribution of young star clusters (YSCs) in four nearby star forming galaxies (NGC 628, NGC 4449, M51, a…
The Spatial Evolution of Star Clusters in NGC 628 with JWST
Anne S. M. Buckner, Ana Duarte-Cabral, Angela Adamo +23
We examine the spatial distribution of star clusters in NGC 628 using the statistical tool INDICATE to quantify clustering tendencies. Our sample, based on HST and JWST observation…
Isolated massive star candidates in NGC 4242 with GULP
Pietro Facchini, Eva K. Grebel, Anna Pasquali +16
There is considerable debate on how massive stars form, including whether a high-mass star must always form with a population of low-mass stars or whether it ca…
The Calibration of Short Wavelength Polycyclic Aromatic Hydrocarbon Emission as Star Formation Rate Indicators with JWST
