Jet Formation and Collimation in AGN and microQuasars
C. Sauty, K. Tsinganos, E. Trussoni
We briefly review our current understanding for the formation, acceleration and collimation of winds to jets associated with compact astrophysical objects such as AGN and microQuas…
EVN Observations of GRS1915+105
L. Feretti, G. Giovannini, M. Tordi +12
We obtained EVN observations of the X-ray transient source GRS1915+105 in its radio-loud state. In 2 images obtained before a major flare, the source is resolved, showing two oppos…
Phase Variability in the Optical Polarization of GRO J1655--40
M. Gliozzi, G. Bodo, G. Ghisellini +2
We present the results of the new optical polarimetric observations of the superluminal source GRO J1655--40, carried out in July 1997, with the multichannel photopolarimeter of th…
ROSAT observations of the B2 radio galaxies 1615+35 and 1621+38: implications on the radio source confinement
L. Feretti, R. Fanti, P. Parma +3
We report X-ray observations of the radio galaxies B2 1615+35 (NGC 6109) and B2 1621+38 (NGC 6137), which belong to poor groups of galaxies and are characterized by a "head-tail" s…
