We report the detection of a transient X-ray source toward the Small Magellanic Cloud (SMC) using the X-ray Imaging Spectrometer (XIS) onboard the Suzaku telescope. The source was detected at the edge of the XIS image during a routine observation of the calibration source 1E 0102.2–7219, a supernova remnant in the SMC. We constrained the source position using ray-tracing simulations. No such tr...
The optical-UV and X-ray instruments on-board XMM-Newton provide an excellent opportunity to perform simultaneous observations of violently variable objects over a broad wavelength range. The UV and X-ray bright BL Lac object PKS 2155–304 has been repeatedly observed with XMM-Newton about twice per year. In this paper, we present a detailed analysis of the simultaneous multi-wavelength variabil...
