Dust emission from 3C radio galaxies and quasars: New ISO observations favour the unified scheme
In order to test the unified scheme for luminous radio galaxies and quasars we observed 10 galaxy/quasar pairs from the 3CR catalogue with ISOPHOT at infrared wavelengths between 5 and 180 μm. Each pair was selected such that both the 178 MHz luminosity and the redshift match as close as possible between the radio galaxy and the quasar in order to minimize effects of cosmic evolution. 13 of the...
متن کامل3c 129 : the Gmrt Observations
We present radio maps of the head-tail radio galaxy, 3C 129 at 240 and 610 MHz using the Giant Metrewave Radio Telescope. We have studied in detail the morphology of the source and the distribution of spectral index over the object. We find large-scale spectral steepening along the jet away from the core. Using synchrotron spectral ageing theory, we infer the age (time since particle accelerati...
متن کاملThe Host Galaxies of Three Radio-loud Quasars: 3c 48, 3c 345, and B2 1425]2671 Sofia Kirhakos
Observations with the Wide-Field/Planetary Camera-2 of the Hubble Space T elescope are presented for three radio-loud quasars : 3C 48 (z\ 0.367), B2 1425]267 (z\ 0.366), and 3C 345 (z\ 0.594). All three quasars have luminous (D4 ] L*) galaxies as hosts, which are either elliptical (B2 1425]267 and 3C345) or interacting (3C 48), and all hosts are 0.5È1.0 mag bluer in V [I than other galaxies wit...
متن کاملMAGIC observations and multifrequency properties of the flat spectrum radio quasar 3C 279 in 2011
Aims. We study the multifrequency emission and spectral properties of the quasar 3C 279 aimed at identifying the radiation processes taking place in the source. Methods. We observed 3C 279 in very-high-energy (VHE, E > 100 GeV) γ-rays, with the MAGIC telescopes during 2011, for the first time in stereoscopic mode. We combined these measurements with observations at other energy bands: in high-e...
