An HST Wide Field Survey of the Galactic Bulge: Overview, Strategy, and First Results

Sean K. Terry, Jay Anderson, Charles A. Beichman +13

We present an HST imaging survey of a 1.1 sq. degree sky area toward the Milky Way Galactic Bulge. This field significantly overlaps with the upcoming Nancy Grace Roman Galactic Bu…

Predictions of the Nancy Grace Roman Space Telescope Galactic Exoplanet Survey. IV. Lens Mass and Distance Measurements

Sean K. Terry, Etienne Bachelet, Farzaneh Zohrabi +54

As part of the Galactic Bulge Time Domain Survey (GBTDS), the Nancy Grace Roman Galactic Exoplanet Survey (RGES) will use microlensing to discover cold outer planets and free-float…

Is Liller 1 a building block of the Galactic bulge? -- Evidence with APOGEE

Anna Liptrott, Ricardo P. Schiavon, Andrew C. Mason +10

Liller 1 is a stellar system orbiting within the inner 0.8kpc of the Galactic centre, characterised by a wide spread in age and metallicity, indicating a high mass. Liller 1 has be…

A Near-Infrared Extinction and Reddening Map Towards the Galactic Bulge Using UKIRT

Aiden S. Zelakiewicz, Samson A. Johnson, B. Scott Gaudi +3

The Galactic bulge is one of the most information-dense regions to study resolved stellar populations, variables, and transients, such as microlensing events. Studies toward the Ga…

The Galactic Bulge exploration IV.: RR~Lyrae stars as traces of the Galactic bar -- 3D and 5D analysis, extinction variation

Z. Prudil, A. Kunder, L. Beraldo e Silva +10

We created new reddening maps and derived new extinction laws from visual to near-infrared passbands using improved RR~Lyrae period-absolute magnitude-metallicity relations, thus e…

Accurate, Precise, and Physically Self-consistent Ages and Metallicities for 400,000 Solar Neighborhood Subgiant Branch Stars

David M. Nataf, Kevin C. Schlaufman, Henrique Reggiani +1

Age is the most difficult fundamental stellar parameter to infer for isolated stars. While isochrone-based ages are in general imprecise for both main sequence dwarfs and red giant…
