We present a 60 ks Chandra ACIS-S observation of the thermal composite supernova remnant 3C 391. The southeast-northwest elongated morphology is similar to that previously found in radio and X-ray stu...
Highly clumpy structure of the thermal composite supernova remnant 3C 391 unveiled by Chandra
3C 391 (G31.9+0.0) ISM
2014/12/24
The nature of the internal thermal X-ray emission seen in “thermal composite” supernova remnants is still uncertain. Chandra observation of the 3C391 shows a southeast–northwest elongated morphology a...
Chandra ACIS Spectroscopy of N157B: A Young Composite Supernova Remnant in a Superbubble
PSR J0537− 6910 N157B SNR 0538-691
2014/12/23
We present a Chandra ACIS observations of N157B, a young supernova remnant (SNR) located in the 30 Doradus star formation region of the Large Magellanic Cloud. This remnant contains the most energetic...
Molecular environment and thermal X-ray spectroscopy of the semicircular young composite supernova remnant 3C 396
ISM individual (3C 396 G39.2− 0.3) – ISM molecules – supernova remnants
2010/11/15
We have investigated the molecular gas environment of the semicircular composite supernova rem-
nant (SNR) 3C 396 in multiwavelengths and performed a Chandra spatially resolved thermal X-ray
spectro...
A High Signal-to-Noise Ratio Composite Spectrum of Gamma-ray Burst Afterglows
Galaxies high-redshift gamma rays bursts
2010/11/10
We present a composite spectrum of 60 long duration gamma-ray burst (GRB) afterglows with
redshifts in the range 0.35 < z < 6.7 observed with low resolution optical spectra. The composite spectrum co...
