ROSAT all-sky survey image of the entire Vela SNR. Red, green, and blue correspond to 0.1–0.5 keV, 0.5–1.3 keV, and 1.3–2.0 keV, respectively. The labels A–F indicate the " shrapnels " discovered by Aschenbach et al. (1995). The yellow square shows the field of view of Suzaku/XIS on Vela shrapnel B (see section 3).

The Vela supernova remnant (SNR) is a very ideal target for studying the detailed structure, since it has a quite large angular diameter (∼ 8 •). In this proceeding, we first review the previous observations of several "shrapnels", the fragments of the ejecta protruding beyond the primary blast-shock front. Then, we report the preliminary results o...

The well-studied X-ray/Optical/Radio supernova remnant DDB 1-15 (CXOM31 J004327.8+411829; r3-63) in M31 has been investigated with archival XMM-Newton and Chandra observations. The timing data from XMM-Newton reveals a power density spectrum (PDS) characteristic of accreting compact objects in X-ray binaries (XRBs). The PDS shows features typical o...
A Type Ia supernova explosion starts in a white dwarf as a laminar deflagration at the centre of the star and soon several hydrodynamic instabilities – in particular, the Rayleigh–Taylor (R–T) instability – begin to act. In previous work, we addressed the propagation of an initially laminar thermonuclear flame in the presence of a magnetic field as...
Supernova remnants play a key role in galactic evolution. Therefore, studying them intensively can improve our understanding of the process. In this project, we studied the neutral hydrogen shell GSH054-00+003 located at RA 292.75º and DEC 18.25º that was found in the SETHI dataset. We found its reference velocity to be 3km/s. After matching it wit...
We present X-ray proper-motion measurements of the forward shock and reverse-shocked ejecta in Tycho's supernova remnant, based on three sets of archival Chandra data taken in 2000, 2003, and 2007. We find that the proper motion of the edge of the remnant (i.e., the forward shock and protruding ejecta knots) varies from 020 yr–1 (expansion index m...
In an effort to better understand the evolution of composite supernova
remnants (SNRs) and the eventual fate of relativistic particles injected by
their pulsars, we present a multifaceted investigation of the interaction
between a pulsar wind nebula (PWN) and its host SNR G327.1-1.1. Our 350 ks
Chandra X-ray observations of SNR G327.1-1.1 reveal a...
