First-Year Spectroscopy for the SDSS-II Supernova Survey
Chen Zheng, Roger W. Romani, Masao Sako +77
This paper presents spectroscopy of supernovae discovered in the first season of the Sloan Digital Sky Survey-II Supernova Survey. This program searches for and measures multi-band…
Light and Motion in SDSS Stripe 82: The Catalogues
D. M. Bramich, S. Vidrih, L. Wyrzykowski +19
We present a new public archive of light-motion curves in Sloan Digital Sky Survey (SDSS) Stripe 82, covering 99 deg in right ascension from RA = 20.7 h to 3.3 h and spanning 2.52…
The Sloan Digital Sky Survey-II Supernova Survey: Search Algorithm and Follow-up Observations
Masao Sako, B. Bassett, A. Becker +47
The Sloan Digital Sky Survey-II Supernova Survey has identified a large number of new transient sources in a 300 sq. deg. region along the celestial equator during its first two se…
The Sloan Digital Sky Survey Quasar Catalog IV. Fifth Data Release
Donald P. Schneider, Patrick B. Hall, Gordon T. Richards +41
We present the fourth edition of the Sloan Digital Sky Survey (SDSS) Quasar Catalog. The catalog contains 77,429 objects; this is an increase of over 30,000 entries since the previ…
An Improved Photometric Calibration of the Sloan Digital Sky Survey Imaging Data
N. Padmanabhan, D. J. Schlegel, D. P. Finkbeiner +21
We present an algorithm to photometrically calibrate wide field optical imaging surveys, that simultaneously solves for the calibration parameters and relative stellar fluxes using…
Different Velocity Dependences of Physical Conditions of High- and Low-Ionization Lines in Broad-Line Regions
Stephanie A. Snedden, C. Martin Gaskell
We present results from a study of high- and low-ionization emission line ratios as a function of projected velocity for a sample of eight active galactic nuclei (AGNs). Our result…
