A Comparison of Star-Forming Clumps and Tidal Tails in Local Mergers and High Redshift Galaxies
Debra Meloy Elmegreen, Bruce G. Elmegreen, Bradley C. Whitmore +8
The Clusters, Clumps, Dust, and Gas in Extreme Star-Forming Galaxies (CCDG) survey with the Hubble Space Telescope includes multi-wavelength imaging of 13 galaxies less than 100 Mp…
Distances to PHANGS Galaxies: New Tip of the Red Giant Branch Measurements and Adopted Distances
Gagandeep S. Anand, Janice C. Lee, Schuyler D. Van Dyk +29
PHANGS-HST is an ultraviolet-optical imaging survey of 38 spiral galaxies within ~20 Mpc. Combined with the PHANGS-ALMA, PHANGS-MUSE surveys and other multiwavelength data, the dat…
LEGUS and Halpha-LEGUS Observations of Star Clusters in NGC 4449: Improved Ages and the Fraction of Light in Clusters as a Function of Age
Bradley C. Whitmore, Rupali Chandar, Janice Lee +16
We present a new catalog and results for the cluster system of the starburst galaxy NGC 4449 based on multi-band imaging observations taken as part of the LEGUS and Halpha-LEGUS su…
Mass Functions of Giant Molecular Clouds and Young Star Clusters in Six Nearby Galaxies
Angus Mok, Rupali Chandar, S. Michael Fall
We compare the mass functions of young star clusters (ages Myr) and giant molecular clouds (GMCs) in six galaxies that cover a large range in mass, metallicity, and star…
Candidate LBV stars in galaxy NGC 7793 found via HST photometry + MUSE spectroscopy
Aida Wofford, Vanesa Ramirez, Janice C. Lee +21
Only about 19 Galactic and 25 extra-galactic bona-fide Luminous Blue Variables (LBVs) are known to date. This incomplete census prevents our understanding of this crucial phase of…
The Strikingly Metal-Rich Halo of the Sombrero Galaxy
Roger E. Cohen, Paul Goudfrooij, Matteo Correnti +5
The nature of the Sombrero galaxy (M 104 = NGC 4594) has remained elusive despite many observational studies at a variety of wavelengths. Here we present Hubble Space Telescope ima…
