Further Evidence that Some Quasars Originate in Nearby Galaxies: NGC3628
Abstract
NGC3628 is a well-studied starburst/low level AGN galaxy in the Leo Triplet noted for its extensive outgassed plumes of neutral hydrogen. Catalogued QSOs are shown to be concentrated around NGC3628 and aligned with HI plumes. The chance that the three nearest quasars would accidentally fall as close as they do is <= 0.01. The nearest quasar has a redshift of z = 2.15 and is at the tip of an X-ray filament emerging along the minor axis plume. Location at this point has an accidental probability of ~ 2x10-4. In addition an unusual optical filament also points directly at this quasar.
