The low-mass and structured stellar halo of M83 argues against a merger origin for its starburst and extended neutral hydrogen disk
Eric F. Bell, Benjamin Harmsen, Matthew Cosby +12
A merger origin has been suggested for M83's massive, metal-rich extended HI disk and nuclear starburst. We observe M83's stellar halo to test this idea. We train nearest-neighbor…
Clumpy, dense gas in the outflow of NGC 1266
Justin Atsushi Otter, Katherine Alatalo, Kate Rowlands +23
Outflows are one of the most spectacular mechanisms through which active galactic nuclei (AGN) impact their host galaxy, though the role of AGN-driven outflows in global star forma…
The Timescales of Embedded Star Formation as Observed in STARFORGE
Tobin M. Wainer, Julianne J. Dalcanton, Michael Y. Grudić +7
Star formation occurs within dusty molecular clouds that are then disrupted by stellar feedback. However, the timing and physical mechanisms that govern the transition from deeply…
Stars Born in the Wind: M82's Outflow and Halo Star Formation
Vaishnav V. Rao, Adam Smercina, Eric F. Bell +8
Starburst galaxies, like M82, launch kiloparsec-scale galactic outflows that interact with the circumgalactic medium (CGM) in complex ways. Apart from enriching the CGM with metals…
Resolving Individual Stars in Nearby Large Galaxies with the Habitable Worlds Observatory
Adam Smercina, Tara Fetherolf, Eric W. Koch +3
The varied and dynamic evolutionary histories of galaxies give rise to the stunning diversity in their properties that we observe in the present-day universe. HST, and now JWST, ha…
The Star Formation History and Evolution of the Ultra-Diffuse M81 Satellite F8D1
Adam Smercina, Eric F. Bell, Benjamin F. Williams +15
We present deep HST imaging of one of the nearest ultra-diffuse galaxies (UDGs) outside of the Local Group: F8D1, a satellite of M81 known to be tidally disrupting. UDGs are an eni…
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…
The NGC3109 Satellite System: The First Systematic Resolved Search for Dwarf Galaxies Around a SMC-mass Host
Amandine Doliva-Dolinsky, Burçin Mutlu-Pakdil, Denija Crnojević +38
We report the results of the deepest search to date for dwarf galaxies around NGC3109, a barred spiral galaxy with a mass similar to that of the Small Magellanic Cloud (SMC), using…
Streams, Shells, and Substructures in the Accretion-Built Stellar Halo of NGC 300
Catherine E. Fielder, David J. Sand, Michael G. Jones +27
We present deep optical observations of the stellar halo of NGC 300, an LMC-mass galaxy, acquired with the DEEP sub-component of the DECam Local Volume Exploration survey (DELVE) u…
