Multifrequency study of SNR J0533–7202, a new supernova remnant in the LMC
We present a detailed study of Australia Telescope Compact Array (ATCA) observations of a newly discovered Large Magellanic Cloud (LMC) supernova remnant (SNR), SNR J0533–7202. This object follows a horseshoe morphology, with a size 37 pc × 28 pc (1-pc uncertainty in each direction). It exhibits a radio spectrum with the intrinsic synchrotron spectral index of α=–0.47±0.06 between 73 and 6 cm. ...
متن کاملMulti - frequency Study of the LMC Supernova Remnant ( SNR ) B 0513 – 692 and New SNR Candidate J 051327 – 6911
We present a new multi-wavelength study of supernova remnant (SNR) B0513–692 in the Large Magellanic Cloud (LMC). The remnant also has a strong, superposed, essentially unresolved, but unrelated radio source at its north-western edge, J051324– 691049. This is identified as a likely compact H ii region based on related optical imaging and spectroscopy. We use the Australia Telescope Compact Arra...
متن کاملROSAT and ASCA Observations of the Crab-Like Supernova Remnant N157B in the Large Magellanic Cloud
We report the results of ROSAT and ASCA X-ray observations of the supernova remnant N157B (or 30 Dor B, SNR 0539-69.1) in the Large Magellanic Cloud. For comparison, we also briefly describe the results on SNR 0540-69.3, the only confirmed Crab-like remnant in the Cloud. The X-ray emission from N157B can be decomposed into a bright comet-shaped feature, superimposed on a diffuse emission region...
متن کاملXMM-Newton observation of SNR J0533−7202 in the Large Magellanic Cloud
Aims. We present an X-ray study of the supernova remnant SNR J0533−7202 in the Large Magellanic Cloud (LMC) and determine its physical characteristics based on its X-ray emission. Methods. We observed SNR J0533−7202 with XMM-Newton (background flare-filtered exposure times of 18 ks EPIC-pn and 31 ks EPIC-MOS1, EPIC-MOS2). We produced X-ray images of the supernova remnant, performed an X-ray spe...
متن کاملThe Chandra View of the Supernova Remnant 0506−68.0 in the Large Magellanic Cloud
A new Chandra observation of SNR 0506−68.0 (also called N23) reveals a complex, highly structured morphology in the low energy X-ray band and an isolated compact central object in the high energy band. Spectral analysis indicates that the X-ray emission overall is dominated by thermal gas whose composition is consistent with swept-up ambient material. There is a strong gradient in ambient densi...
