The Distances of SNRs Kes 69 and G21.5-0.9 from HI and 13CO Spectra
Wenwu Tian, Denis A. Leahy
We obtain new HI and CO images around Supernova Remnants (SNR) Kes 69 and G21.5-0.9. By comparing HI spectra with CO emission spectra, we significantly revise the kin…
Distance Determination to the Crab-like PWN G54.1+0.3 and Search for its Supernova Remnant Shell
D. A. Leahy, W. W. Tian, Q. D. Wang
We discover a large-scale shell G53.9+0.2 around the Crab-like pulsar wind nebula (PWN) G54.1+0.3 with 1420 MHz continuum VLA observations. This is confirmed by a new infrared imag…
Discovery of the radio and X-ray counterpart of TeV Gamma-ray source HESS J1731-347
W. W. Tian, D. A. Leahy, M. Haverkorn +1
We discover a faint shell-type radio and X-ray source, G353.6-0.7, associated with HESS J1731-347. G353.6-0.7 is likely an old supernova remnant (SNR), based on radio (0.8 GHz, 1.4…
The Distances of SNR W41 and overlapping HII regions
Denis A. Leahy, Wenwu Tian
New HI images from the VLA Galactic Plane Survey show prominent absorption features associated with the supernovae remnant G23.3-0.3 (SNR W41). We highlight the HI absorption spect…
Radio and X-ray images of SNR G18.8+0.3 interacting with molecular clouds
W. W. Tian, D. A. Leahy, Q. D. Wang
New HI images from the VLA Galactic Plane Survey (VGPS) show clear absorption features associated with the supernova remnant (SNR) G18.8+0.3. High-resolution CO images revea…
Discovery of A New Faint Radio SNR G108.2-0.6
W. W. Tian, D. A. Leahy, T. J. Foster
A new faint and large shell-type radio Supernova Remnant (SNR) G108.2-0.6 has been discovered in the Canadian Galactic Plane Survey (CGPS). The SNR shows an elliptical shell-type s…
