A Tale of Two Disks: Mapping the Milky Way with the Final Data Release of APOGEE
Julie Imig, Cathryn Price, Jon A. Holtzman +24
We present new maps of the Milky Way disk showing the distribution of metallicity ([Fe/H]), -element abundances ([Mg/Fe]), and stellar age, using a sample of 66,496 red giant st…
Standardized Luminosity of the Tip of the Red Giant Branch utilizing Multiple Fields in NGC 4258 and the CATs Algorithm
Siyang Li, Adam G. Riess, Dan Scolnic +6
The Tip of the Red Giant Branch provides a luminous standard candle for calibrating distance ladders that reach Type Ia supernova (SN Ia) hosts. However, recent work reveals that t…
Metallicity Gradient of Barred Galaxies with TYPHOON
Qian-Hui Chen, Kathryn Grasha, Andrew J. Battisti +5
Bars play an important role in mixing material in the inner regions of galaxies and stimulating radial migration. Previous observations have found evidence for the impact of a bar…
The JWST Resolved Stellar Populations Early Release Science Program II. Survey Overview
Daniel R. Weisz, Kristen B. W. McQuinn, Alessandro Savino +39
We present the JWST Resolved Stellar Populations Early Release Science (ERS) science program. We obtained 27.5 hours of NIRCam and NIRISS imaging of three targets in the Local Grou…
A Comparative Analysis of the Chemical Compositions of Gaia-Enceladus/Sausage and Milky Way Satellites using APOGEE
Laura Fernandes, Andrew C. Mason, Danny Horta +11
We use data from the 17th data release of the Apache Point Observatory Galactic Evolution Experiment (APOGEE 2) to contrast the chemical composition of the recently discovered Gaia…
Elemental abundances in M31: Individual and Coadded Spectroscopic [Fe/H] and [α/Fe] throughout the M31 Halo with SPLASH
J. Leigh Wojno, Karoline M. Gilbert, Evan N. Kirby +6
We present spectroscopic chemical abundances of red giant branch (RGB) stars in Andromeda (M31), using medium resolution () spectra obtained via the Spectroscopic and Ph…
