| 1st Abstract | Supernova Remnant RX J1713.7-3946 emits synchrotron X-rays and very high energy gamma-rays. Recently, thermal X-ray line emission is detected from ejecta plasma. CO and HI observations indicate that a highly inhomogeneous medium surrounding the SNR. It is interacting with dense molecular clouds in the northwest and the southwest of the remnant. The origin of the gamma-ray emission from RX J1713.7-3946 is still uncertain. Detection of rapid variability in X-ray emission from RX J1713.7-3946 indicates the magnetic field B ~ mG. In this work, we investigate the time variation in X-ray flux, luminosity and photon index of RX J1713.7-3946. For this investigation, we study the northwest part of the remnant using Suzaku data in 2006 and 2010. We present preliminary results based on our analysis and interpretations about these X-ray time variability. |

| 2nd Abstract | Synchrotron X-ray emission, which arises from electrons being accelerated by the shock front of a supernova remnant (SNR), has been detected predominantly in young shell type remnants. The detection of synchrotron X-ray emission allows one to investigate the properties of the underlying particle population. Using a ~470 ks Suzaku observation of SNR W49B, we search for evidence of non-thermal X-ray emission by extracting X-ray spectra from different regions across the remnant. We model each spectra using a combination of thermal emission and non-thermal models in an attempt to characterise the presence of X-ray synchrotron emission. Here we present our initial results and preliminary conclusions. |
