A Comparison of the Extra Nuclear X-ray and Radio Features in M87
D. E. Harris, F. Owen, J. A. Biretta +1
ROSAT High Resolution Imager (HRI) data from eight observations have been co-added to obtain an effective exposure of 230 ksec. We have identified a number of features and regions…
VLBI observations of 3C273 at 22 GHz and 43 GHz. II: test of Synchrotron Self-Compton process
F. Mantovani, W. Junor, I. M. McHardy +1
The VLBI observations at 22 GHz and 43 GHz of the quasar 3C273 obtained during a multi-frequency campaign in late 1992 in the radio, millimetre and X-ray bands allow us to derive t…
VLBI observations of 3C273 at 22GHz and 43 GHz. I: Search for short time-scale structural variation
F. Mantovani, W. Junor, C. Valerio +1
The results of VLBI observations of the quasar 3C273, obtained during a multi-frequency campaign in late 1992 in the radio, millimeter and X-ray bands are presented and discussed.…
Large bent jets in the inner region of CSSs
F. Mantovani, W. Junor, M. Bondi +5
The class of Compact Steep-spectrum Sources is dominated by double-lobed objects (70%). The remaining 30% are jet-dominated objects, with the jet brightened either by Doppler boost…
