New evidence for keV X-ray variability of QSO 0241+622.
Abstract
The results of two observations of the X-ray QSO 0241 + 622 were compared, in order to find evidence of X-ray variability in the keV range. The observations were performed using the Imaging Proportional Counter (IPC) instrument on board the Einstein Observatory satellite. Evidence is presented for a variability of more than a factor of two for an IPC flux of 0.5-4.5 keV.
