Simultaneous fits in ISIS on the example of GRO J1008-57
Matthias Kühnel, Sebastian Müller, Ingo Kreykenbohm +9
Parallel computing and steadily increasing computation speed have led to a new tool for analyzing multiple datasets and datatypes: fitting several datasets simultaneously. With thi…
The Goodness of Simultaneous Fits in ISIS
Matthias Kühnel, Sebastian Falkner, Christoph Grossberger +15
In a previous work, we introduced a tool for analyzing multiple datasets simultaneously, which has been implemented into ISIS. This tool was used to fit many spectra of X-ray binar…
Evidence for an Evolving Cyclotron Line Energy in 4U 1538-522
Paul B. Hemphill, Richard E. Rothschild, Felix Fürst +6
We have performed a full time- and luminosity-resolved spectral analysis of the high-mass X-ray binary 4U 1538-522 using the available RXTE, INTEGRAL, and Suzaku data, examining bo…
Revealing the broad iron Kalpha line in Cygnus X-1 through simultaneous XMM-Newton, RXTE, and INTEGRAL observations
Refiz Duro, Thomas Dauser, Victoria Grinberg +15
We report on the analysis of the broad Fe Kalpha line feature of Cygnus X-1 in the spectra of four simultaneous hard intermediate state observations made with the X-ray Multiple Mi…
