What is the redshift of the gamma- ray BL Lac source S4 0954+65?
M. Landoni, R. Falomo, A. Treves +2
High signal-to-noise ratio spectroscopic observations of the BL Lac object S4 0954+65 at the alleged redshift z = 0.367 are presented. This source was detected at gamma frequencies…
The evolution of Radio Loud Quasar host galaxies: AO observations at z = 3
R. Falomo, J. K. Kotilainen, R. Scarpa +2
We report on ESO--VLT adaptive optics imaging of one radio-loud quasar at z 3. In spite of the large distance of the object we are able to detect its surrounding extended ne…
Near-Infrared Observations of BL Lacertae Host Galaxies
C. C. Cheung, C. Megan Urry, Riccardo Scarpa +1
Multi-band near-infrared images of twelve BL Lacertae objects were obtained with the 2.5m telescope at the Las Campanas Observatory in order to determine the properties of their un…
Broad-band continuum and line emission of the gamma-ray blazar PKS 0537-441
E. Pian, R. Falomo, R. C. Hartman +10
PKS 0537-441, a bright gamma-ray emitting blazar, was observed at radio, optical, UV and X-ray frequencies during various EGRET pointings, often quasi-simultaneously. In 1995 the o…
A survey of extended radio jets in AGN with Chandra and HST: First Results
Rita M. Sambruna, L. Maraschi, F. Tavecchio +5
We present the first results from an X-ray and optical survey of a sample of AGN radio jets with Chandra and HST. We focus here on the first six sources observed at X-rays, in four…
The Fundamental Plane of Radio Galaxies
D. Bettoni, R. Falomo, G. Fasano +3
We collected photometrical and dynamical data for 73 low red-shift (z<0.2) Radio Galaxies (LzRG) in order to study their Fundamental Plane (FP). For 22 sources we also present new…
