Faraday Rotation Structure on Kiloparsec Scales in the Radio Lobes of Centaurus A
We present the results of an Australia Telescope Compact Array 1.4GHz spectropolarimetric aperture synthesis survey of 34 square degrees centred on Centaurus A—NGC 5128. A catalogue of 1005 extragalactic compact radio sources in the field to a continuum flux density of 3mJy beam is provided along with a table of Faraday rotation measures (RMs) and linear polarised intensities for the 28% of sou...
متن کاملThe giant lobes of Centaurus A observed at 118 MHz with the Murchison Widefield Array
We present new wide-field observations of Centaurus A (Cen A) and the surrounding region at 118 MHz with the Murchison Widefield Array (MWA) 32-tile prototype, with which we investigate the spectral-index distribution of Cen A’s giant radio lobes. We compare our images to 1.4 GHz maps of Cen A and compute spectral indices using temperature-temperature plots and spectral tomography. We find that...
متن کاملGiant Lobes of Centaurus a Radio Galaxy Observed with the Suzaku X-ray Satellite
We report on Suzaku observations of selected regions within the Southern giant lobe of the radio galaxy Centaurus A. In our analysis we focus on distinct X-ray features detected with the X-ray Imaging Spectrometer within the range 0.5 − 10 keV, some of which are likely associated with fine structure of the lobe revealed by recent high-quality radio intensity and polarization maps. With the avai...
متن کاملDetection of Bulk Motions in the Icm of the Centaurus Cluster
Several recent numerical simulations of off-center cluster mergers predict that significant angular momentum with associated velocities of a few ×10 km s can be imparted to the resulting cluster. Such gas bulk velocities can be detected by the Doppler shift of X-ray spectral lines with ASCA spectrometers. Using two ASCA observations of the Centaurus cluster (Abell 3526), we produced a velocity ...
متن کاملCentaurus A – NGC 5128
The Astronomy and Astrophysics Review Manuscript-Nr. Summary. At a distance of 3.4 Mpc, NGC 5128 (Centaurus A) is by far the nearest active radio galaxy. It is often considered to be the prototype Fanaroff-Riley Class I 'low-luminosity' radio galaxy, and as such it plays an important role in our understanding of a major class of active galaxies. Its proximity has spawned numerous detailed inves...
