The Discovery of a High Redshift X-ray Emitting QSO Very Close to the Nucleus of NGC 7319

Abstract

A strong X-ray source only 8" from the nucleus of the Sy2 galaxy NGC 7319 in Stephan's Quintet has been discovered by Chandra. We have identified the optical counterpart and show it is a QSO with $z_e=2.114$. It is also a ULX with $L_x=1.5x10^{40}ergse{c}^{-1}$. From the optical spectra of the QSO and interstellar gas in the galaxy (z = .022) we show that it is very likely that the QSO and the gas are interacting.
