Multi-frequency radio-continuum study of the LMC SNR N206 (Goat's Eye) and its "zig-zag" PWN
M. Ghavam, Z. J. Smeaton, M. D. Filipovic +17
We present new radio-continuum observations of the Large Magellanic Cloud (LMC) supernova remnant (SNR) N206, which we give the name "Goat's Eye". Goat's Eye contains an interior r…
Multipole Analysis and Application to Supernova Remnant X-ray Images
Denis A. Leahy, S. Ranasinghe, J. Hansen +2
We develop a multipole analysis method for images with a circular boundary, then apply it to supernova remnant (SNR) images. The morphology of SNR images is related to several fact…
Distances, Radial Distribution and Total Number of Galactic Supernova Remnants
S. Ranasinghe, D. Leahy
We present a table of 215 SNRs with distances. New distances are found to SNR G of kpc using HI absorption spectra, and to 5 other SNRs using maser/molecu…
Evolutionary Models for 43 Galactic Supernova Remnants with Distances and X-ray Spectra
D. A. Leahy, S. Ranasinghe. M. Gelowitz
The X-ray emission from a supernova remnant (SNR) is a powerful diagnostic of the state of the shocked plasma. The temperature (kT) and the emission measure (EM) of the shocked-gas…
Distance and Evolutionary States of Supernova Remnant G18.9-1.1 and Candidate G28.6+0.0
S. Ranasinghe, D. Leahy, W. W. Tian
HI spectra of the supernova remnant G18.9-1.1 and the supernova remnant candidate G28.6+0.0 are analyzed. We compared the spectra to CO emission spectra and to spectra of HI…
Multipole Analysis of Radio Continuum Images of Supernova Remnants: Comparison of Type Ia and Core Collapse
Sujith Ranasinghe, Denis Leahy
A multipole expansion analysis is applied to 1420 MHz radio continuum images of supernova remnants (SNRs) in order to compare Type Ia and core collapse (CC) SNRs. Because the radio…
