TL;DR: The Australian SKA Pathfinder (ASKAP) as mentioned in this paper is aimed squarely in this frequency range, and achieves instantaneous wide-area imaging through the development and deployment of phase-array feed systems on parabolic reflectors.
Journal ArticleDOI
Radio/X-ray correlation in the low/hard state of GX 339-4
TL;DR: In this article, the authors present the results of a long-term study of the black hole candidate GX 339 4 using simultaneous radio and X-ray observations performed between 1997 and 2000.
Journal ArticleDOI
A Warped Accretion Disk and Wide-Angle Outflow in the Inner Parsec of the Circinus Galaxy
Lincoln J. Greenhill,Roy Booth,Simon Ellingsen,J. R. Herrnstein,J. R. Herrnstein,David L. Jauncey,P. M. McCulloch,James M. Moran,Ray P. Norris,John Reynolds,Anastasios Tzioumis +10 more
TL;DR: In this paper, the first VLBI maps of H2O maser emission (λ 1.3 cm) in the nucleus of the Circinus galaxy, constructed from data obtained with the Australia Telescope Long Baseline Array, were presented.

TL;DR: The Australian SKA Pathfinder (ASKAP) is a technology demonstrator aimed in the mid-frequency range, and achieves instantaneous wide-area imaging through the development and deployment of phased-array feed systems on parabolic reflectors as mentioned in this paper.
Journal ArticleDOI
Radiatively efficient accreting black holes in the hard state: the case study of H1743-322
Mickael Coriat,Stephane Corbel,Stephane Corbel,L. Prat,James Miller-Jones,D. Cseh,Anastasios Tzioumis,Catherine Brocksopp,Jerome Rodriguez,Rob Fender,Gregory R. Sivakoff +10 more
TL;DR: In this article, the radio and X-ray emission of H1743−322 were investigated and it was shown that the inner accretion flow is radiatively efficient during the hard state, in contrast to what is usually assumed for black hole Xray binaries in this spectral state.
