Early Spectra of the Gravitational Wave Source GW170817: Evolution of a Neutron Star Merger
B. J. Shappee, J. D. Simon, M. R. Drout +33
On 2017 August 17, Swope Supernova Survey 2017a (SSS17a) was discovered as the optical counterpart of the binary neutron star gravitational wave event GW170817. We report time-seri…
Constraining cosmic scatter in the Galactic halo through a differential analysis of metal-poor stars
Henrique Reggiani, Jorge Meléndez, Chiaki Kobayashi +2
We present the abundances of Li, Na, Mg, Al, Si, Ca, Sc, Ti, V, Cr, Mn, Co, Ni, Zn, Sr, Y, Zr, and Ba in a wide metallicity range ( [Fe/H] ). Using the differen…
APOGEE Chemical Abundances of the Sagittarius Dwarf Galaxy
Sten Hasselquist, Matthew Shetrone, Verne Smith +23
The Apache Point Observatory Galactic Evolution Experiment (APOGEE) provides the opportunity to measure elemental abundances for C, N, O, Na, Mg, Al, Si, P, K, Ca, V, Cr, Mn, Fe, C…
Atypical Mg-poor Milky Way field stars with globular cluster second-generation like chemical patterns
J. G. Fernández-Trincado, O. Zamora, D. A. Garcia-Hernandez +48
We report the peculiar chemical abundance patterns of eleven atypical Milky Way (MW) field red giant stars observed by the Apache Point Observatory Galactic Evolution Experiment (A…
Carbon-enhanced metal-poor stars in the SDSS-APOGEE database
Collin L. Kielty, Kim A. Venn, Nicholas B. Loewen +5
We identify six new CEMP stars ([C/Fe]>+0.7 and [Fe/H]< -1.8) and another seven likely candidates within the APOGEE database following Data Release 12. These stars have chemical co…
RAVE J203843.2-002333: The first highly r-process-enhanced star identified in the RAVE survey
Vinicius M. Placco, Erika M. Holmbeck, Anna Frebel +9
We report the discovery of RAVE J203843.2-002333, a bright (V = 12.73), very metal-poor ([Fe/H] = -2.91), r-process-enhanced ([Eu/Fe] = +1.64 and [Ba/Eu] = -0.81) star selected fro…
Chemical Cartography. I. A Carbonicity Map of the Galactic Halo
Young Sun Lee, Timothy C. Beers, Young Kwang Kim +5
We present the first map of carbonicity, [C/Fe], for the halo system of the Milky Way, based on a sample of over 100,000 main-sequence turnoff stars with available spectroscopy fro…
The Case for Electron Re-Acceleration at Galaxy Cluster Shocks
Reinout J. van Weeren, Felipe Andrade-Santos, William A. Dawson +16
On the largest scales, the Universe consists of voids and filaments making up the cosmic web. Galaxy clusters are located at the knots in this web, at the intersection of filaments…
