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…
A High Resolution X-ray spectrum of the LINER Galaxy M81
M. J. Page, A. A. Breeveld, R. Soria +1
We present the soft X-ray spectrum of the LINER galaxy M81 from a long observation with the XMM-Newton RGS. As well as continuum emission from the active nucleus, the spectrum show…
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…
X-ray Beaming in the High Magnetic Field Pulsar GX 1+4
D. K. Galloway, K. Wu
Pulse profiles from X-ray pulsars often exhibit strong energy dependence and both periodic and aperiodic variations with time. The great variety of profiles observed in various sou…
