Radio Monitoring of Supernova 2001ig: The First Year
S. D. Ryder, E. Sadler, R. Subrahmanyan +3
Supernova 2001ig in NGC 7424 has been observed with the Australia Telescope Compact Array at ~2 week intervals since its discovery, making this the best-studied Type IIb radio supe…
Searching for Clusters of Galaxies with SUMSS
H. J. Buttery, G. Cotter, R. W. Hunstead +1
Statistical overdensities of radio sources in the NRAO VLA Sky Survey (NVSS) catalogue have proven to be signposts to high-redshift clusters of galaxies. A similar search for overd…
Radio Emission from the X-ray transient XTE J1550-564
D. Hannikainen, K. Wu, Campbell-Wilson +6
We report multifrequency radio observations of XTE J1550-564 obtained with the Molonglo Observatory Synthesis Telescope and the Australia Telescope Compact Array at the time of its…
The Fornax Spectroscopic Survey I. Survey Strategy and Preliminary Results on the Redshift Distribution of a Complete Sample of Stars and Galaxies
M. J. Drinkwater, S. Phillipps, J. B. Jones +6
The Fornax Spectroscopic Survey will use the Two degree Field spectrograph (2dF) of the Anglo-Australian Telescope to obtain spectra for a complete sample of all 14000 objects with…
Radio Observations of Merging Clusters in the Shapley Concentration
T. Venturi, S. Bardelli, G. Zambelli +2
In this paper we present the first results of a radio survey at 22 cm in the central region of the Shapley Concentration, carried out with the Australia Telescope Compact Array. In…
Diffusive shock acceleration in extragalactic jets
M. Micono, N. Zurlo, S. Massaglia +2
We calculate the temporal evolution of distributions of relativistic electrons subject to synchrotron and adiabatic processes and Fermi-like acceleration in shocks. The shocks resu…
