GRS 1915+105: The first three months with INTEGRAL
D. C. Hannikainen, O. Vilhu, J. Rodriguez +19
GRS 1915+105 is being observed as part of an Open Time monitoring program with INTEGRAL. Three out of six observations from the monitoring program are presented here, in addition t…
Luminosity functions of X-ray binaries and the dynamical history of their host galaxies
K. Wu, A. F. Tennant, D. A. Swartz +2
The X-ray sources observed in nearby galaxies show brightness distributions (log(N(>S))--log(S) curves) which can be described as single or broken power laws. Single power-law dist…
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…
Low and High Angular Momentum Accretion Flows in BHCs: Case Study of XTE J1550-564
Roberto Soria, Kinwah Wu, Diana Hannikainen +2
The 1998 outburst of XTE J1550-564 started with a hard X-ray spike, rising in less than a day and declining after 3-4 days; at the same time, the soft X-ray flux was rising with a…
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…
MOST Radio Monitoring of GX 339-4
D. C. Hannikainen, R. W. Hunstead, D. Campbell-Wilson +1
The Molonglo Observatory Synthesis Telescope (MOST) has been monitoring the candidate Galactic black hole binary system GX 339-4 at 843 MHz since 1994 April. We present the results…
