The Discovery of a High Redshift X-ray Emitting QSO Very Close to the Nucleus of NGC 7319
Pasquale Galianni, E. M. Burbidge, H. Arp +3
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 i…
Dust and Diffuse Interstellar Bands in the z_a = 0.524 Absorption System toward AO 0235+164
V. T. Junkkarinen, Ross D. Cohen, E. A. Beaver +3
We present new HST STIS NUV-MAMA and STIS CCD observations of the BL Lac object AO 0235+164 and the intervening damped Ly alpha (DLA) line at z_a = 0.524. The line profile gives N(…
The double radio source 3C343.1: A galaxy-QSO pair with very different redshifts
H. Arp, E. M. Burbidge, G. Burbidge
The strong radio source 3C343.1 consists of a galaxy and a QSO separated by no more than about 0.25 arcsec. The chance of this being an accidental superposition is conservatively 1…
