Radio synthesis observations of 3C 296, 3C 442A and 3C 449 at 0.4, 1.4 and 2.7 GHz

VLBA polarimetric observations of 3C 286 at 5 GHz

Polarimetric observations at 5 GHz using the VLBA are reported of the compact steep spectrum source 3C 286. There are two flat spectrum knots but both are too highly polarized to be a typical core component and both appear to be resolved in VLBA measurements. The morphology and polarization structure of this source is also quite distinct from typical core–jet sources. It is suggested that the c...

3c 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...

Sub-Arcsecond Imaging of 3C 123: 108-GHz Continuum Observations of the Radio Hotspots

We present the results of sub-arcsecond 108 GHz continuum interferometric observations toward the radio luminous galaxy 3C 123. Using multi-array observations, we utilize the high u,v dynamic range of the BIMA millimeter array to sample fully spatial scales ranging from 0. 5 to 50. This allows us to make one-to-one comparisons of millimeter-wavelength emission in the radio lobes and hotspots to...

Gas Sloshing and Radio Galaxy Dynamics in the Core of the 3c 449 Group

We present results from a 140 ks Chandra/ACIS-S observation of the hot gas around the canonical FR I radio galaxy 3C 449. An earlier, shorter 30 ks Chandra observation of the group gas showed an unusual entropy distribution and a surface brightness edge in the gas that could be a strong shock around the inner radio lobes. In our deeper data we find no evidence for a temperature increase inside ...
