SUMMARY OF SEQUENCE NUMBER 700081
Title: LOW-LUMINOSITY ACTIVE GALACTIC NUCLEI IN NEARBY GALAXIES
Observer: FEIGELSON
Subject Category: Active Galaxies and Quasars
Seq: 700081 ObsId: 00409
Long-term Plan bin: no LTS bin
ABSTRACT
The rapid cosmic evolution of the QSO population predicts that a substantial fraction of massive galaxies today chould contain supermassive black holes. A recent optical emission line survey finds that over 40% of all nearby bright galaxies may harbor LLAGNs. These sources may contribute substantially to the X-ray background radiation. This snapshot survey provides brief ACIS images of the nuclei for a volume-limited sample of 25 candidate LLAGN plus several prototype galaxies of different classes.
