The Large Magellanic Cloud through the lens of the James Webb Space Telescope: Binaries and the mass function in the galaxy's outskirts
M. V. Legnardi, F. Muratore, A. P. Milone +16
Nearby galaxies such as the Large Magellanic Cloud (LMC) offer an ideal laboratory to test the initial mass function under different physical conditions, but previous works have be…
A Long Period Stellar-Mass Black Hole Binary in Centauri
Matthew Whitaker, Evan Kerr, Anil Seth +16
Modern simulations of stellar dynamics in globular clusters peg a dominant role for stellar-mass black holes, but direct evidence for black holes in clusters remains limited. We pr…
A Colour-colour Fingerprint Links the UV Upturn in Early-type Galaxies to Second-generation Stars from Dissolved Globular Clusters
Paul Goudfrooij, Andrea Bellini, Thomas M. Brown +1
We address two mass-dependent properties among early-type galaxies (ETGs): (1) abundance ratios [N/Fe] and [Na/Fe], and (2) the centrally concentrated "UV upturn" at far-UV (FUV) w…
Hubble Astrometry for the Local Group and Beyond in the 2030s
S. Tony Sohn, Paul Bennet, Kevin Andrew McKinnon +23
Hubble's long, stable astrometric baseline creates a rare opportunity for discovery in the Local Group and beyond. Many nearby galaxies, streams, and star clusters already have arc…
The Hubble Missing Globular Cluster Survey. III. Astro-photometric catalogs, artificial-star tests, and improved absolute proper motions
M. Libralato, A. Bellini, D. Massari +17
The Hubble Missing Globular Cluster Survey (MGCS) has taken one of the last opportunities to complete the census of Galactic globular clusters (GCs) started by past Hubble Space Te…
oMEGACat. X. Shedding light on the disrupted dwarf galaxy of Omega Centauri
Stefano Souza, Nadine Neumayer, Anil C. Seth +15
Omega Centauri (Cen) is the most massive and chemically complex star cluster in the Milky Way and is widely regarded as the surviving nuclear star cluster of an accreted dwar…
