The radio-ultraviolet spectral energy distribution of the jet in 3C273
S. Jester, H. -J. Roeser, K. Meisenheimer +1
We present deep VLA and HST observations of the large-scale jet in 3C 273 matched to 0.3" resolution. The observed spectra show a significant flattening in the infrared-ultraviolet…
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…
Did Most High-Redshift Quasars Escape Detection?
C. Wolf, K. Meisenheimer, H. -J. Roeser +1
We present follow-up spectroscopy to the Calar Alto Deep Imaging Survey (CADIS), reporting on the quasars in the CADIS 16h-field, and including preliminary data from two other fiel…
