We report here the results of high-resolution and spectral imaging X-ray observations , with both the ROSAT HRI and PSPC , of the field surrounding the nearby ( D = 64 Mpc ) type 1 Seyfert galaxy IC 4329A and its giant lenticular companion IC 4329 .
Many point sources are detected , the brightest being associated with IC 4329A itself , having an extremely bright X-ray luminosity of 6 \times 10 ^ { 43 } erg s ^ { -1 } , and spectral properties compatible with a single power-law model ( \Gamma = 1.73 ) , with a spectral break at 0.7 keV .
Two other bright sources are detected associated with the companion galaxy IC 4329 , and a likely quasar 14 ^ { \prime } to the south-west .
We have also established , through optical observations taken at the European Southern Observatory , that three further X-ray point sources , intriguingly positioned with respect to IC 4329A , are in fact nothing to do with the system , and are merely foreground and background objects .

In addition to point source emission , residual , unresolved emission is detected surrounding the IC 4329A/ IC 4329 pair , extending for some 200 kpc .
This emission appears markedly two-component , comprising of a spectrally hard and smooth component , circularly-distributed about the central galaxy pair , and a spectrally soft , more clumpy component , positioned almost entirely to the south-east of IC 4329A .
The hard component of the residual emission itself appears two-component , one component being due to the ‘ wings ’ of the intensely bright IC 4329A source , the other , apparently due to hot ( \sim 1.5 keV ) gas , likely associated with the galaxy group of which IC 4329A and IC 4329 are members .
The soft component of the residual emission may be a larger version of the superwinds seen around some ultraluminous far-infrared galaxies , or may even represent a ‘ stripped wake ’ of intragroup gas .
Evidence for shocked gas due to the central IC 4329A/ IC4329 interaction is also found between the two central galaxies .
