Kinematics of the parsec-scale radio jet in 3C48
T. An, X. Y. Hong, M. J. Hardcastle +6
We present results on the compact steep-spectrum quasar 3C 48 from observations with the VLBA, MERLIN and EVN at multiple radio frequencies. In the 1.5-GHz VLBI images, the radio j…
A giant radio halo in the massive and merging cluster Abell 1351
S. Giacintucci, T. Venturi, R. Cassano +2
We report on the detection of diffuse radio emission in the X-ray luminous and massive galaxy cluster A1351 (z=0.322) using archival Very Large Array data at 1.4 GHz. Given its cen…
AGN feedback in galaxy groups: a joint GMRT/X-ray study
S. Giacintucci, J. M. Vrtilek, E. O'Sullivan +5
We present an ongoing study of 18 nearby galaxy groups, chosen for the availability of Chandra and/or XMM-Newton data and evidence for AGN/hot intragroup gas interaction. We have o…
The Bologna complete sample of nearby radio sources: II -- phase referenced observations of faint nuclear sources
E. Liuzzo, G. Giovannini, M. Giroletti +1
To study statistical properties of different classes of sources, it is necessary to observe a sample that is free of selection effects. To do this, we initiated a project to observ…
Tailed radio galaxies as tracers of galaxy clusters. Serendipitous discoveries with the GMRT
S. Giacintucci, T. Venturi
We report on the discovery of four new radio galaxies with tailed morphology. Tailed radio galaxies are generally found in rich environments, therefore their presence can be used a…
AGN Feedback in groups and clusters of galaxies
S. Raychaudhury, S. Giacintucci, E. O'Sullivan +5
The lack of very cool gas at the cores of groups and clusters of galaxies, even where the cooling time is significantly shorter than the Hubble time, has been interpreted as eviden…
