New ATLAS9 And MARCS Model Atmosphere Grids For The Apache Point Observatory Galactic Evolution Experiment (APOGEE)
(2012-10)
We present a new grid of model photospheres for the SDSS-III/APOGEE survey of stellar populations of the Galaxy, calculated using the ATLAS9 and MARCS codes. New opacity distribution functions were generated to calculate ...
GEMS : Galaxy Fitting Catalogs and Testing Parametric Galaxy Fitting Codes : GALFIT and GIM2D
(2007-10)
In the context of measuring the structures of intermediate-redshift galaxies with HST ACS surveys, we tune, test, and compare two widely used fitting codes (GALFIT and GIM2D) for fitting single-component Sersic models to ...
Target Selection For The Apache Point Observatory Galactic Evolution Experiment (APOGEE)
(2013-10)
The Apache Point Observatory Galactic Evolution Experiment (APOGEE) is a high-resolution infrared spectroscopic survey spanning all Galactic environments (i.e., bulge, disk, and halo), with the principal goal of constraining ...
Overview Of The SDSS-IV Manga Survey: Mapping Nearby Galaxies At Apache Point Observatory
(2015-01)
We present an overview of a new integral field spectroscopic survey called MaNGA (Mapping Nearby Galaxies at Apache Point Observatory), one of three core programs in the fourth-generation Sloan Digital Sky Survey (SDSS-IV) ...
Characteristics Of Kepler Planetary Candidates Based On The First Data Set
(2011-02)
In the spring of 2009, the Kepler Mission commenced high-precision photometry on nearly 156,000 stars to determine the frequency and characteristics of small exoplanets, conduct a guest observer program, and obtain ...
The Apache Point Observatory Galactic Evolution Experiment: First Detection of High-Velocity Milky Way Bar Stars
(2012-08)
Commissioning observations with the Apache Point Observatory Galactic Evolution Experiment (APOGEE), part of the Sloan Digital Sky Survey III, have produced radial velocities (RVs) for similar to 4700 K/M-giant stars in ...
Type II-P Supernovae From The SDSS-II Supernova Survey And The Standardized Candle Method
(2010-01)
We apply the Standardized Candle Method (SCM) for Type II Plateau supernovae (SNe II-P), which relates the velocity of the ejecta of a SN to its luminosity during the plateau, to 15 SNe II-P discovered over the three season ...
GEMS Survey Data and Catalog
(2008-01)
We describe the data reduction and object cataloging for the GEMS survey, a large-area (800 arcmin(2)) two-band (F606W and F850LP) imaging survey with the Advanced Camera for Surveys on the Hubble Space Telescope, centered ...
Galactic Globular and Open Clusters in the Sloan DIGITal Sky Survey. I. Crowded-Field Photometry and Cluster Fiducial Sequences in Ugriz
(2008-12)
We present photometry for globular and open cluster stars observed with the Sloan Digital Sky Survey (SDSS). In order to exploit the over 100 million stellar objects with r < 22:5 mag observed by SDSS, we need to understand ...
The Seventh Data Release of the Sloan Digital Sky Survey
(2009-05)
This paper describes the Seventh Data Release of the Sloan Digital Sky Survey (SDSS), marking the completion of the original goals of the SDSS and the end of the phase known as SDSS-II. It includes 11,663 deg(2) of imaging ...
