Spatially-resolved Thermal Continuum Absorption against the Supernova Remnant W49B
We present sub-arcminute resolution imaging of the Galactic supernova remnant W49B at 74 MHz (25) and 327 MHz (6), the former being the lowest frequency at which the source has been resolved. While the 327 MHz image shows a shell-like morphology similar to that seen at higher frequencies, the 74 MHz image is considerably Present address: Department of Physics and Astronomy, University of South ...
متن کاملSuzaku Observation of 30 Dor C: A Supernova Remnant with the Largest Non-Thermal Shell
This paper reports on the Suzaku results of thermal and non-thermal features of 30 Dor C, a supernova remnant (SNR) in a superbubble of the Large Magellanic Cloud (LMC). The west rim exhibits a nonthermal X-ray spectrum with no thermal component. A single power-law model is rejected but a powerlaw model with spectral cutoff is accepted. The cutoff frequency of (3− 7)× 10 Hz is the highest among...
متن کاملXMM-Newton observations of HESS J1813–178 reveal a composite Supernova remnant
Aims. We present X-ray and 12CO(J=1–0) observations of the very-high-energy (VHE) γ-ray source HESS J1813–178 with the aim of understanding the origin of the γ-ray emission. Methods. High-angular resolution X-ray studies of the VHE γ-ray emission region are performed using 18.6 ks of XMM-Newton data, taken on HESS J1813–178 in October 2005. Using this dataset we are able to undertake spectral a...
متن کاملChandra Observations of a Non-Thermal Supernova Remnant Candidate AX J1843.8−0352 and its Surroundings
We present the Chandra results of AX J1843.8−0352, a supernova remnant (SNR) recently identified with ASCA. Chandra spatially resolved two components from this SNR: non-thermal and thermal ones. The morphology of the nonthermal component is clumpy and elliptical, elongated from the north to the south with a mean diameter of about 9. The spectrum is fitted with a power-law model of photon index ...
متن کاملPersei): Detection of localized Non-thermal X-ray Emission from a Miniature Supernova Remnant
I present the data of the shell of classical Nova Persei (1901) obtained by the Advanced CCD Imaging Spectrometer S3 detector on-board Chandra Observatory. The X-ray nebula is affected mostly by the complex interstellar medium around the nova and has not developed a regular shell. The X-ray nebula is lumpy and asymmetric with bulk of emission coming from the southwestern quadrant. The brightest...
