Properties of the Scattering Screen in Front of Scintillating Quasar PKS 1257-326
H. E. Bignall, D. L. Jauncey, J. E. J. Lovell +3
PKS 1257-326 is a quasar showing extremely unusual, rapid interstellar scintillation (ISS), which has persisted for at least a decade. Simultaneous observations with the VLA and AT…
The Australian experience with the PC-EVN recorder
R. Dodson, S. Tingay, C. West +4
We report on our experiences using the Metsahovi Radio Observatory's (MRO) VLBI Standard Interface (VSI, Whitney 2002) recorder in a number of astronomical applications. The PC-EVN…
Coupling of the X-ray and radio emission in the black hole candidate a nd compact jet source GX 339-4
S. Corbel, R. P. Fender, A. K. Tzioumis +4
We report the results of a long-term campaign of radio, soft- and hard- X-ray observations of the galactic black hole candidate GX 339-4. In the Low-Hard X-ray state the system dis…
Supernova 1987A: A young supernova remnant in an aspherical progenitor wind
B. M. Gaensler, R. N. Manchester, L. Staveley-Smith +4
The interaction between the ejecta from Supernova 1987A and surrounding material is producing steadily brightening radio and X-ray emission. The new-born supernova remnant has been…
The Deep X-ray Radio Blazar Survey (DXRBS)
Paolo Padovani, Eric Perlman, Paolo Giommi +4
We have undertaken a survey for blazars by correlating the ROSAT WGACAT database with publicly available radio catalogs, restricting our candidate list to serendipitous flat-spectr…
High-resolution radio observations of GX 339-4
R. P. Fender, R. E. Spencer, S. J. Newell +1
We present radio observations of the black hole candidate X-ray binary GX 339-4 with the Australia Telescope compact array. Mapping of the highest resolution 3.5 cm data reveals a…
