The JWST Resolved Stellar Populations Early Release Science Program IV: The Star Formation History of the Local Group Galaxy WLM
Kristen. B. W. McQuinn, Max J. B. Newman, Alessandro Savino +23
We present the first star formation history (SFH) and age-metallicity relation (AMR) derived from resolved stellar populations imaged with the JWST NIRCam instrument. The target is…
The Hubble Space Telescope Survey of M31 Satellite Galaxies. III. Calibrating the Horizontal Branch as an Age Indicator for Nearby Galaxies
Connor Jennings, Alessandro Savino, Daniel Weisz +14
We present a new method for measuring the mean age of old/intermediate stellar populations in resolved, metal-poor () galaxies using only th…
Where do stars explode in the ISM? -- The distribution of dense gas around evolved massive stars in M33
Sumit K. Sarbadhicary, Jordan Wagner, Eric W. Koch +27
The effect of supernovae (SNe) on star-formation in the interstellar medium (ISM) depends sensitively on where SNe explode with respect to ISM clouds. Observationally, SN ISM envir…
The Panchromatic Hubble Andromeda Treasury: Triangulum Extended Region (PHATTER). V. The Structure of M33 in Resolved Stellar Populations
Adam Smercina, Julianne J. Dalcanton, Benjamin F. Williams +13
We present a detailed analysis of the the structure of the Local Group flocculent spiral galaxy M33, as measured using the Panchromatic Hubble Andromeda Treasury Triangulum Extende…
HST UV Spectroscopy of the Dwarf Starburst Galaxy Pox 186
Noah S. J. Rogers, Claudia M. Scarlata, Evan D. Skillman +4
Studying the galaxies responsible for reionization is often conducted through local reionization-era analogs; however, many of these local analogs are too massive to be representat…
The Panchromatic Hubble Andromeda Treasury XXI. The Legacy Resolved Stellar Photometry Catalog
Benjamin F. Williams, Meredith Durbin, Dustin Lang +14
We present the final legacy version of stellar photometry for the Panchromatic Hubble Andromeda Treasury (PHAT) survey. We have reprocessed all of the Hubble Space Telescope (HST)…
