Quasars and Galaxy Clusters Paired Across NGC 4410
H. Arp, E. M. Burbidge, D. Carosati
The aim is to investigate the region of the sky around NGC4410/Mrk1325 for objects which are physically associated with this active, double nucleus galaxy. We use archived data to…
Ultraluminous X-ray Sources, High Redshift QSOs and Active Galaxies
G. Burbidge, E. M. Burbidge, H. C. Arp +1
It is shown that all of the 32 point X-ray sources which lie within about 10' of the centre of nearby galaxies, and which have so far been optically identified are high redshift ob…
An anomalous concentration of QSOs around NGC 3079
E. M. Burbidge, G. Burbidge, H. C. Arp +1
It is shown that there are at least 21 QSOs within 1 degree of the nearby active spiral galaxy NGC3079. Many of them are bright (mag<18) so that the surface density of those closer…
X-ray Bright QSO's around NGC 3079
H. Arp, E. M. Burbidge
NGC 3079 is a very active, disturbed galaxy which has been observed to have X-ray and radio ejections from it as well as an optical superbubble along its minor axis. Here we show t…
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(…
