Quasar Winds as Dust Factories at High Redshift
Martin Elvis ; Massimo Marengo & Margarita Karovska ;
Date 19 Nov 2003
Subject astro-ph
AffiliationHarvard-Smithsonian Center for Astrophysics
AbstractWinds from AGN and quasars will form large amounts of dust, as the cool gas in these winds passes through the (pressure, temperature) region where dust is formed in AGB stars. Conditions in the gas are benign to dust at these radii. As a result quasar winds may be a major source of dust at high redshifts, obviating a difficulty with current observations, and requiring far less dust to exist at early epochs.
