An improved view of cosmic-ray transport and the galactic outflow in NGC 253
Shengtao Wang, George Heald, Stefan W. Duchesne +11
The nearly edge-on starburst galaxy NGC 253 exhibits extended multiwavelength halo emission, making it an ideal laboratory for studying disk-halo transport. We present improved ASK…
Tracing Red Giant Members of the Globular Cluster Palomar 5 with APOGEE and Gaia
Allyson A. Sheffield, Sarah Pearson, Lenin F. Nolasco +5
The globular cluster Palomar 5 (Pal 5) is in the process of being tidally shredded as it orbits the Milky Way. Its core is currently at a heliocentric distance of ~21 kpc, near apo…
Exploring the potential for kinematically colder HI component as a tracer for star-forming gas in nearby galaxies
Hye-Jin Park, Andrew J. Battisti, Antoine Marchal +10
Atomic hydrogen (HI) dominates the mass of the cold interstellar medium, undergoing thermal condensation to form molecular gas and fuel star formation. Kinematically colder HI comp…
Quantifying azimuthal variations within the interstellar medium of z ~ 0 spiral galaxies with the TYPHOON survey
Qian-Hui Chen, Kathryn Grasha, Andrew J. Battisti +13
Most star formation in the local Universe occurs in spiral galaxies, but their origin remains an unanswered question. Various theories have been proposed to explain the development…
The APO-K2 Catalog. II. Accurate Stellar Ages for Red Giant Branch Stars across the Milky Way
Jack T. Warfield, Joel C. Zinn, Jessica Schonhut-Stasik +11
We present stellar age determinations for 4661 red giant branch stars in the APO-K2 catalog, derived using mass estimates from K2 asteroseismology from the K2 Galactic Archaeology…
The APOGEE Value Added Catalogue of Galactic globular cluster stars
Ricardo P. Schiavon, Siân G. Phillips, Natalie Myers +17
We introduce the SDSS/APOGEE Value Added Catalogue of Galactic Globular Cluster (GC) Stars. The catalogue is the result of a critical search of the APOGEE data release 17 (DR17) ca…
