Scylla: Observational Evidence for an Order of Magnitude in Dust Mass Opacity Evolution with ISM Density in the Large Magellanic Cloud
Christina W. Lindberg, Christopher J. R. Clark, Claire E. Murray +11
The emissivity of dust is known to vary greatly with radiative environment, density, grain chemistry, and geometry. Discrepancies between dust mass surface densities derived from f…
Scylla VI: Parsec-Scale Dust Extinction Maps in the SMC and LMC
Christina W. Lindberg, Claire E. Murray, Christopher J. R. Clark +14
We present a novel methodology for mapping dust extinction in nearby galaxies at parsec-scale resolution. We apply it to HST 68 fields within the Small and Large Magellanic Clouds…
Scylla at APOGEE: The Impact of Starbursts on the Chemical Evolution of the Magellanic Clouds
Ivanna Escala, Kristen B. W. McQuinn, Sten Hasselquist +11
Owing to their proximity to the Milky Way, the Large and Small Magellanic Clouds (L/SMC) uniquely probe the evolution of low-mass galaxies undergoing mutual interactions. In this w…
Unveiling Massive Main-Sequence Stars in Sextans A through Panchromatic Photometry
Maude Gull, Daniel R. Weisz, Yumi Choi +9
We present a study of the metal-poor (~6% Z_sun) massive (>8 M_sun) main-sequence star population in the star-forming dwarf galaxy Sextans A. By modeling near-UV to near-IR photome…
Scylla V: Constraints on the spatial and temporal distribution of bursts and the interaction history of the Magellanic Clouds from their resolved stellar populations
Clare Burhenne, Kristen B. W. McQuinn, Roger E. Cohen +9
We measure the star formation histories (SFHs) from the Scylla survey in approximately 98,000 pc^2 and 75,000 pc^2 of the SMC and LMC, respectively, using deep Hubble Space Telesco…
A Low Metallicity Massive Contact Binary Star System Candidate in WLM identified by Hubble and James Webb Space Telescope imaging
Maude Gull, Daniel R. Weisz, Kareem El-Badry +15
We present archival HST and JWST ultraviolet through near infrared time series photometric observations of a massive minimal-contact binary candidate in the metal-poor galaxy WLM (…
