ROSAT X-ray survey of an area 10 degrees square around the active radio galaxy Centaurus A.


Abstract (from CDS):

Diffuse X-ray material extends in an irregular, broad filament for more than 5 degrees north east of the giant radio elliptical, NGC 5128 (Cen A). In the opposite direction the X-ray extension is clearly traced for about 2 degrees, making an overall line of X-rays of greater than 7deg on the sky originating from Cen A. The direction of this line coincides almost exactly with the direction of the X-ray jet, and its associated radio jet, in the interior of Cen A. At a slightly different angle, within the accuracy of measurement along the X-ray counter jet, is encountered the radio and X-ray galaxy NGC 5090. Its presence in the X-ray ejection from Cen A supports the precedent from other associations that NGC 5090 is physically associated with Cen A. In the hardest X-rays there is some indication that the radio lobes from Cen A are edge brightened. Positions and known identifications of sources in the field are given. Some preliminary estimates of the properties of this extensive X-ray material which has apparently been ejected from this active galaxy are given.
