The X-ray spectro-timing properties of a major radio flare episode in Cygnus X-3
K. I. I. Koljonen, M. L. McCollough, D. C. Hannikainen +1
We have performed a principal component analysis on the X-ray spectra of the microquasar Cygnus X-3 from RXTE, INTEGRAL and Swift during a major flare ejection event in 2006 May-Ju…
2006 May-July Major Radio Flare episodes in Cygnus X-3: spectro-timing analysis of the X-ray data
K. I. I. Koljonen, M. L. McCollough, D. C. Hannikainen +1
We analyse in detail the X-ray data of the microquasar Cygnus X-3 obtained during major radio flaring episodes in 2006 with multiple observatories. The analysis consists of two par…
Understanding Cygnus X-3 Through Multi-Wavelength Studies
Michael McCollough, Karri Koljonen, Diana Hannikainen +5
Cygnus X-3 is a unique microquasar which shows X-ray state changes, strong radio emission, and relativistic jets. It is also an unusual X-ray binary with the mass-donating companio…
Variability and spectral modeling of the hard X-ray emission of GX 339-4 in a bright low/hard state
Robert Droulans, Renaud Belmont, Julien Malzac +1
We study the high-energy emission of the Galactic black hole candidate GX 339-4 using INTEGRAL/SPI and simultaneous RXTE/PCA data. By the end of January 2007, when it reached its p…
