Self-consistent evolution of gas and cosmic rays in Cygnus A and similar FR II classic double radio sources
Self-consistent evolution cosmic rays
2011/1/10
In Cygnus A and other classical FR II double radio sources, powerful opposing jets from the cores of halo-centered galaxies drive out into the surrounding cluster gas, forming hotspots of shocked and ...
Constraining the Redshift Evolution of FIRST Radio Sources in RCS1 Galaxy Clusters
the Redshift Evolution FIRST Radio Sources
2011/1/13
We conduct a statistical analysis of the radio source population in galaxy clusters as a function of redshift by matching radio sources from the Faint Images of the Radio Sky at Twenty-Centimeters (FI...
A 22-year Southern Sky Survey for Transient and Variable Radio Sources using the Molonglo Observatory Synthesis Telescope
radio continuum: general stars: pulsars:general stars: flare techniques:image processing catalogues supernovae general
2010/11/9
We describe a 22-year survey for variable and transient radio sources, performed with
archival images taken with the Molonglo Observatory Synthesis Telescope (MOST).
This survey covers 2775 deg2 of ...
Dying Radio Sources in Clusters
Radio continuum galaxies - Galaxies active - Galaxies jets - Galaxies clusters
2010/11/10
Aims. In this work we present the study of five ‘dying’ nearby (z ≤ 0.2) radio galaxies belonging to the WENSS minisurvey and to the B2 bright catalogs: WNB1734+6407, WNB1829+6911, WNB1851+5707, B2 01...
The radio properties of infrared-faint radio sources
Galaxies active Galaxies high-redshift
2010/11/15
Context. Infrared-faint radio sources (IFRS) are objects that have flux densities of several mJy at 1.4 GHz, but that are invisible at 3.6 m when using sensitive Spitzer observations with Jy sensiti...
Intermittent activity of radio sources. Accretion instabilities and jet precession
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2011/1/4
We consider the radiation pressure instability operating on short timescales 10^3 - 10^6 years in the accretion disk around a supermassive black hole as the origin of the intermittent activity of radi...
