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…

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…

The Galactic Bulge exploration III.: Calcium Triplet Metallicities for RR Lyrae Stars

Andrea Kunder, Zdenek Prudil, Claire Skaggs +5

RR Lyrae stars are excellent tracers of stellar populations for old, metal-poor components in the Milky Way Galaxy and the Local Group. Their luminosities have a metallicity-depend…

The GALAH survey: Tracing the Milky Way's formation and evolution through RR Lyrae stars

Valentina D'Orazi, Nicholas Storm, Andrew R. Casey +39

Stellar mergers and accretion events have been crucial in shaping the evolution of the Milky Way (MW). These events have been dynamically identified and chemically characterised us…
