Determining Ages of APOGEE Giants with Known Distances
Diane K Feuillet, Jo Bovy, Jon Holtzman +4
We present a sample of local red giant stars observed using the New Mexico State University 1 m telescope with the APOGEE spectrograph, for which we estimate stellar ages and the a…
SDSS-IV/MaNGA: Spectrophotometric Calibration Technique
Renbin Yan, Christy Tremonti, Matthew A. Bershady +19
Mapping Nearby Galaxies at Apache Point Observatory (MaNGA), one of three core programs in the Sloan Digital Sky Survey-IV (SDSS-IV), is an integral-field spectroscopic (IFS) surve…
The SDSS-IV extended Baryon Oscillation Spectroscopic Survey: Overview and Early Data
Kyle S. Dawson, Jean-Paul Kneib, Will J. Percival +143
The Extended Baryon Oscillation Spectroscopic Survey (eBOSS) will conduct novel cosmological observations using the BOSS spectrograph at Apache Point Observatory. Observations will…
An efficient, compact, and versatile fiber double scrambler for high precision radial velocity instruments
Samuel Halverson, Arpita Roy, Suvrath Mahadevan +5
We present the design and test results of a compact optical fiber double-scrambler for high-resolution Doppler radial velocity instruments. This device consists of a single optic:…
Observing Strategy for the SDSS-IV/MaNGA IFU Galaxy Survey
David R. Law, Renbin Yan, Matthew A. Bershady +11
MaNGA (Mapping Nearby Galaxies at Apache Point Observatory) is an integral-field spectroscopic survey of 10,000 nearby galaxies that is one of three core programs in the fourth-gen…
P-MaNGA: Gradients in Recent Star Formation Histories as Diagnostics for Galaxy Growth and Death
Cheng Li, Enci Wang, Lin Lin +31
We present an analysis of the data produced by the MaNGA prototype run (P-MaNGA), aiming to test how the radial gradients in recent star formation histories, as indicated by the 40…
