Dwarf Galaxy Number Counts within 25 Mpc: Predictions from Local Group Analogues in TNG50

Evangela E. Shread, Joanna M. Piotrowska, Daniel R. Weisz +2

The modern generation of wide-field galaxy surveys, such as LSST, Euclid and Roman, will enable studies of dwarf galaxies beyond the Local…

The Karl G. Jansky Very Large Array Local Group L-band Survey (LGLBS)

Eric W. Koch, Adam K. Leroy, Erik W. Rosolowsky +45

We present the Local Group L-Band Survey (LGLBS), a Karl G. Jansky Very Large Array (VLA) survey producing the highest quality 21-cm and 1-2 GHz radio continuum images to date for…

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 (…

The Local Ultraviolet to Infrared Treasury II. Refining Star Formation Histories of Ten Metal-Poor Dwarf Galaxies with Simultaneous UV-Optical Two-CMD Fitting

Yumi Choi, Karoline M. Gilbert, Benjamin F. Williams +10

We present the star formation histories (SFHs) of ten metal-poor (<12% Zsun), star-forming dwarf galaxies from the Local Ultraviolet to Infrared Treasury (LUVIT) survey. The derive…

The JWST Resolved Stellar Populations Early Release Science Program. VIII. The Spatially Resolved Star Formation History of WLM

Roger E. Cohen, Kristen B. W. McQuinn, Alessandro Savino +17

We measure radial stellar age gradients in the relatively isolated gas-rich dwarf irregular WLM, combining JWST NIRCam and NIRISS imaging with six archival Hubble fields over semi-…

The Local Ultraviolet to Infrared Treasury I. Survey Overview of the Broadband Imaging

Karoline M. Gilbert, Yumi Choi, Martha L. Boyer +21

The Local Ultraviolet to Infrared Treasury (LUVIT) is a Hubble Space Telescope program that combines newly acquired data in the near ultraviolet (NUV), optical, and near infrared (…
