Evolved Supergiants in PHANGS I: Red Supergiants in 19 Galaxies between 5-20 Mpc with HST and JWST
Sumit K. Sarbadhicary, David Thilker, Adam K. Leroy +17
Red supergiants (RSGs) are important for our understanding of supernova progenitors, stellar populations, stellar evolution, mass loss and dust production. Extragalactic surveys of…
Transformational astrophysics and exoplanet science with Habitable Worlds Observatory's High Resolution Imager
Vincent Van Eylen, Richard Massey, Saeeda Awan +167
Habitable Worlds Observatory (HWO) will be NASA's flagship space telescope of the 2040s, designed to search for life on other planets and to transform broad areas of astrophysics.…
Ashes of Creation: JWST Uncovers Silicate Dust in Massive Star Clusters
Daniel Maschmann, Bradley C. Whitmore, David A. Thilker +35
Dust production is a fundamental aspect of the baryonic cycle of star formation. It is known that dust is injected into the interstellar medium during early star formation by super…
PAH Marks the Spot: Digging for Buried Clusters in Nearby Star-forming Galaxies
Gabrielle B. Graham, Daniel A. Dale, Chase L. Smith +39
The joint capabilities of the Hubble Space Telescope (HST) and JWST allow for an unparalleled look at the early lives of star clusters at near- and mid-infrared wavelengths. We pre…
Resolved HII regions in NGC 253: Ionized gas structure and suggestions of a universal density-surface brightness relation
Rebecca L. McClain, Adam K. Leroy, Enrico Congiu +23
We use the full-disk VLT-MUSE mosaic of NGC 253 to identify 2492 HII regions and study their resolved structure. With an average physical resolution of 17 pc, this is one of the la…
Masses, Star-Formation Efficiencies, and Dynamical Evolution of 18,000 HII Regions
Debosmita Pathak, Adam K. Leroy, Ashley. T. Barnes +36
We present measurements of the masses associated with HII regions across 19 nearby star-forming galaxies by combining data from JWST, HST, MUSE, ALMA, VLA, and MeerKAT…
Negative gas-phase metallicity gradients in the narrow line region and galactic disc of local AGN-host galaxies
Amirnezam Amiri, Johan H. Knapen, Bret D. Lehmer +1
The gas-phase metallicity distribution in galaxies provides significant information on their evolution. We report the discovery of negative radial gradients in the gas-phase metall…
Characterization of Two Cool Galaxy Outflow Candidates Using Mid-Infrared Emission from Polycyclic Aromatic Hydrocarbons
Jessica Sutter, Karin Sandstrom, Ryan Chown +22
We characterize two candidate cool galactic outflows in two relatively low mass, highly inclined Virgo cluster galaxies: NGC4424 and NGC4694. Previous analyses of observations usin…
MARTA: The connection between chemical enrichment, feedback, and dust in a Wolf-Rayet galaxy at z2
Mirko Curti, Elisa Cataldi, Francesco Belfiore +17
We present the analysis of the stellar and interstellar medium (ISM) properties of MARTA-4327, a star-forming galaxy at z=2.224 observed by means of deep JWST/NIRSpec spectroscopy…
The Hierarchical Dynamical State of Molecular Gas from 3 to 300 pc in NGC 253
Elias K. Oakes, Christopher M. Faesi, Erik Rosolowsky +25
Understanding how the dynamical state of the interstellar medium (ISM) changes across spatial scales can provide important insights into how the gas is organized and ultimately col…
Duration and properties of the embedded phase of star formation in 37 nearby galaxies from PHANGS-JWST
Lise Ramambason, Mélanie Chevance, Jaeyeon Kim +32
Light reprocessed by dust grains emitting in the infrared allows the study of the physics at play in dusty, embedded regions, where ultraviolet and optical wavelengths are attenuat…
Stripped and Enriched: The Role of Ram-Pressure in Shaping Chemical Enrichment of Galaxies at Intermediate Redshift
Amir H. Khoram, Bianca Poggianti, Alessia Moretti +11
The chemical evolution of galaxies is shaped by their star formation histories and the exchange of gas with their environments. Metallicity provides key insights into these process…
