Discovery of a stellar tidal stream around the Whale galaxy, NGC 4631
David Martinez-Delgado, Elena D'Onghia, Taylor S. Chonis +5
We report the discovery of a giant stellar tidal stream in the halo of NGC 4631, a nearby edge-on spiral galaxy interacting with the spiral NGC 4656, in deep images taken with a 40…
High-resolution, H band Spectroscopy of Be Stars with SDSS-III/APOGEE: I. New Be Stars, Line Identifications, and Line Profiles
S. Drew Chojnowski, David G. Whelan, John P. Wisniewski +26
APOGEE has amassed the largest ever collection of multi-epoch, high-resolution (R~22,500), H-band spectra for B-type emission line (Be) stars. The 128/238 APOGEE Be stars for which…
Global Properties of M31's Stellar Halo from the SPLASH Survey: II. Metallicity Profile
Karoline M. Gilbert, Jason S. Kalirai, Puragra Guhathakurta +9
We present the metallicity distribution of red giant branch (RGB) stars in M31's stellar halo, derived from photometric metallicity estimates for over 1500 spectroscopically confir…
TriAnd and its Siblings: Satellites of Satellites in the Milky Way Halo
A. J. Deason, V. Belokurov, K. M. Hamren +7
We explore the Triangulum-Andromeda (TriAnd) overdensity in the SPLASH (Spectroscopic and Photometric Landscape of Andromeda's Stellar Halo) and SEGUE (the Sloan Extension for Gala…
Exploring Halo Substructure with Giant Stars: The Nature of the Triangulum-Andromeda Stellar Features
Allyson Sheffield, Kathryn Johnston, Steven Majewski +4
As large-scale stellar surveys have become available over the past decade, the ability to detect and characterize substructures in the Galaxy has increased dramatically. These surv…
