Sloan digital sky survey: Early data release

Chris Stoughton, +212 more
TL;DR: The Sloan Digital Sky Survey (SDSS) is an imaging and spectroscopic survey that will eventually cover approximately one-quarter of the celestial sphere and collect spectra of ≈106 galaxies, 100,000 quasars, 30,000 stars, and 30, 000 serendipity targets as discussed by the authors.

Journal ArticleDOI

The discrete correlation function: a new method for analyzing unevenly sampled variability data

TL;DR: In this article, a method for measuring correlation functions without interpolating in the temporal domain is proposed which provides an assumption-free representation of the correlation measured in the data and allows meaningful error estimates.
Journal ArticleDOI

Molecular tori in Seyfert galaxies - Feeding the monster and hiding it

TL;DR: In this paper, the internal state of the clouds and their size distribution function are examined, and it is shown that the Jeans mass scale results in clouds which are individually sufficiently opaque to block out the nucleus.
Journal ArticleDOI

Infrared spectra of obscuring dust tori around active galactic nuclei. I - Calculational method and basic trends

TL;DR: In this article, the authors used a 2D radiative transfer algorithm to calculate the thermally reradiated infrared spectra of the compact dust tori which are thought to surround many AGN.
