The International AGN Watch

Welcome to the AGN Watch Website

The AGN Watch is a consortium of astronomers who have studied the inner structure of active galactic nuclei (AGNs) through continuum and emission-line variability. As a group, we have carried out large-scale multiwavelength monitoring programs using both space-based and ground-based facilities.

At the present time, the AGN Watch has completed all of its projects and is now inactive.

AGN Watch data are intended to be available to anyone who is interested in studying AGN variability. At the present time, nearly all our published light curves and spectra (from IUE, HST, and ground-based telescopes) are available to download from this site.
