A high-resolution multi-wavelength study of the jet in 3C 273
S. Jester, H. -J. Roeser, K. Meisenheimer +2
We present HST images at 622 nm and 300 nm of the optical jet in 3C273 and determine the run of the optical spectral index at 0.2" along the jet. We find no evidence for localized…

The jet of 3C 273 observed with ROSAT HRI
Hermann-Josef Roeser, Klaus Meisenheimer, Martin Neumann +2
ROSAT HRI observations of 3C 273 reveal X-ray emission all along the optically visible jet with the peak of emission at the inner end. Whereas the X-ray emission from the innermost…

74 MHz-VLA-Observation of Coma Berenices with Subarcminute Resolution -- Observation, Data Reduction, and Preliminary Results
T. A. Ensslin, Kronberg, R. A. Perley +1
We report on an ongoing project to map a 15 degree x 15 degree region in Coma Berenices with the new 74 MHz receiver system of the VLA. The field is centered on the Coma cluster of…
