Distances to Supernova Remnants G, G and G and New Molecular Cloud Associations

S. Ranasinghe, D. A. Leahy

Accurate distances to supernova remnants (SNRs) are crucial in determining their size, age, luminosity and evolutionary state. To determine distances, we chose three SNRs from the…

Disentangling the radio emission of the supernova remnant W51C

M. F. Zhang, W. W. Tian, D. A. Leahy +3

We simulate the evolution of supernova remnant (SNR) W51C. The simulation shows the existence of a new northeast edge. We present magnetic field structure of the W51 complex (SNR W…

Kinematic Distance of Galactic Planetary Nebulae

A. Y. Yang, W. W. Tian, H. Zhu +2

We construct \HI~absorption spectra for 18 planetary nebulae (PNe) and their background sources using the data from the International Galactic Plane Survey. We estimate the kinemat…

SNR G349.7+0.2: A gamma-ray source in the far 3 kpc arm of the Galactic center

W. W. Tian, D. A Leahy

We analyze the HI absorption profile for TeV Supernova Remnant (SNR) G349.7+0.2 based on updated knowledge of the inner Galaxy's structure. We significantly revise its kinematic di…

X-ray and Radio Observations of the gamma Cygni Supernova Remnant G78.2+2.1

D. A. Leahy, K. Green, S. Ranasinghe

We analyse \textit{ROSAT} and \textit{Chandra} ACIS X-ray observations and HI absorption spectra of the Cygni supernova remnant (G78.2+2.1, DR4). The \textit{ROSAT} All-Sky-Sur…

High velocity HI is not associated with TeV supernova remnant W51C

W. W. Tian, D. A. Leahy

The recently-detected TeV gamma-ray source HESS J1923+141 coincides with Supernova Remnant (SNR) W51C and the star forming region W51B of the W51 complex. We construct HI absorptio…
