- 21 December 2003
We examine the properties of the host galaxies of 22 623 narrow-line active galactic nuclei (AGN) with 0.02 < z < 0.3 selected from a complete sample of 122 808 galaxies from the Sloan Digital Sky…
THE SEVENTH DATA RELEASE OF THE SLOAN DIGITAL SKY SURVEY
- K. Abazajian, J. Adelman-McCarthy, D. Zucker
- Physics
- 3 December 2008
A series of improvements to the spectroscopic reductions are described, including better flat fielding and improved wavelength calibration at the blue end, better processing of objects with extremely strong narrow emission lines, and an improved determination of stellar metallicities.
Spectral Energy Distributions and Multiwavelength Selection of Type 1 Quasars
- G. Richards, M. Lacy, A. Szalay
- Physics
- 24 January 2006
We present an analysis of the mid-infrared (MIR) and optical properties of type 1 (broad-line) quasars detected by the Spitzer Space Telescope. The MIR color-redshift relation is characterized to z ~…

We examine the properties of the host galaxies of 22,623 narrow-line AGN with 0.02<z<0.3 selected from a complete sample of 122,808 galaxies from the Sloan Digital Sky Survey. We focus on the…
Constraining the Evolution of the Ionizing Background and the Epoch of Reionization with z ∼ 6 Quasars. II. A Sample of 19 Quasars
- X. Fan, M. Strauss, M. Fukugita
- Physics
- 4 December 2005
We study the evolution of the ionization state of the intergalactic medium (IGM) at the end of the reionization epoch using moderate-resolution spectra of a sample of 19 quasars at 5.74 < zem < 6.42…
