Light Curve Morphology Study of UW CrB -- Evidence for a 5 d Superorbital Period
Pasi Hakala, Linnea Hjalmarsdotter, Diana C. Hannikainen +1
Since its discovery in 1990, UW CrB (also known as MS1603+2600) has remained a peculiar source without firm classification. Our current understanding is that it is an Accretion Dis…
Exploring the spreading layer of GX 9+9 using RXTE and INTEGRAL
P. Savolainen, D. C. Hannikainen, O. Vilhu +3
We have fitted ~200 RXTE and INTEGRAL spectra of the neutron star LMXB GX 9+9 from 2002-2007 with a model consisting of a disc blackbody and another blackbody representing the spre…
Spectral variability in Cygnus X-3
L. Hjalmarsdotter, A. A. Zdziarski, A. Szostek +1
We model the broad-band X-ray spectrum of Cyg X-3 in all states displayed by this source as observed by the Rossi X-ray Timing Explorer. From our models, we derive for the first ti…
Peering through the stellar wind of IGR J19140+0951 with simultaneous INTEGRAL/RXTE observations
L. Prat, J. Rodriguez, D. C. Hannikainen +1
We have used the RXTE and INTEGRAL satellites simultaneously to observe the High Mass X-ray binary IGR J19140+0951. The spectra obtained in the 3--80 keV range have allowed us to p…
Two years of INTEGRAL monitoring of GRS 1915+105 Part 1: multiwavelength coverage with INTEGRAL, RXTE, and the Ryle radio Telescope
J. Rodriguez, D. C. Hannikainen, S. E. Shaw +13
(Abridged) We report the results of monitoring observations of the Galactic microquasar GRS 1915+105 performed simultaneously with INTEGRAL and RXTE Ryle . We present the results o…
Two Years of INTEGRAL monitoring of GRS 1915+105 Part 2: X-Ray Spectro-Temporal Analysis
J. Rodriguez, S. E. Shaw, D. C. Hannikainen +14
(abridged) This is the second paper presenting the results of two years of monitoring of GRS 1915+105 with \integral and \rxte and the Ryle Telescope. We present the X-ray spectral…
