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…
KPM: A Flexible and Data-Driven K-Process Model for Nucleosynthesis
Emily J. Griffith, David W. Hogg, Julianne J. Dalcanton +4
The element abundance pattern found in Milky Way disk stars is close to two-dimensional, dominated by production from one prompt process and one delayed process. This simplicity is…
New Dimensions of Galactic Chemical Evolution
David H. Weinberg
Dramatic recent progress in understanding galactic chemical evolution (GCE) has been driven partly by direct observations of the distant past with HST and JWST of stellar abundance…
Buzzard to Cardinal: Improved Mock Catalogs for Large Galaxy Surveys
Chun-Hao To, Joseph DeRose, Risa H. Wechsler +6
We present the Cardinal mock galaxy catalogs, a new version of the Buzzard simulation that has been updated to support ongoing and future cosmological surveys, including DES, DESI,…
A framework to measure the properties of intergalactic metal systems with two-point flux statistics
Naim Göksel Karaçaylı, Paul Martini, David H. Weinberg +16
The abundance, temperature, and clustering of metals in the intergalactic medium are important parameters for understanding their cosmic evolution and quantifying their impact on c…
