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…
The JWST Galactic Center Survey -- A White Paper
Rainer Schoedel, Steve Longmore, Jonny Henshaw +111
The inner hundred parsecs of the Milky Way hosts the nearest supermassive black hole, largest reservoir of dense gas, greatest stellar density, hundreds of massive main and post ma…
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…
