Energy resolved timing of SS433: the supercritical disk and the jets

We propose EPIC observations of the microquasar SS 433, the only knownpersistent superaccretor in the Galaxy. Previous studies of the XMM data showedthat different parts of SS 433 spectrum are dominated by different sources ofradiation. Preliminary results of the crosscorrelation analysis of lowresolution RXTE spectra and existing shortduration XMM data, revealedcorrelations in variability between different energy ranges with time lags of 20s. We request a longer (115 ks) observations in the timing mode to obtain highresolution data, sufficient for the crosscorrelation and variability analysis.These new data will give us the unique opportunity to investigate directly thenonstationary processes and spatial structure of the most inner parts of the supercritical accretion disk. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
