Discovery of molecular shells associated with supernova remnants. (II) Kesteven 75
Yang Su, Yang Chen, Ji Yang +4
The young composite supernova remnant (SNR) Kesteven 75, with a pulsar wind nebula at its center, has an unusual morphology with a bright southern half-shell structure in multiwave…
Discovery of Molecular Shells Associated with Supernova Remnants. I. Kesteven 69
Xin Zhou, Yang Chen, Yang Su +1
Supernova remnant (SNR) Kes 69 is morphologically characterized by brightened radio, infrared, and X-ray emission on the southeastern rim, with the 1720 MHz OH masers detected in t…
Highly Clumpy Structure of the Thermal Composite Supernova Remnant 3C391 Unveiled by Chandra
Yang Chen, Yang Su, Patrick O. Slane +1
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 e…
A Chandra ACIS view of the Thermal Composite Supernova Remnant 3C391
Yang Chen, Yang Su, Patrick O. Slane +1
We present a 60 ks Chandra ACIS-S observation of the thermal composite supernova remnant 3C391. The southeast-northwest elongated morphology is similar to that previously found in…
