HI absorption spectra for Supernova Remnants in the VGPS survey
Denis Leahy, Sujith Ranasinghe
TL;DR
This study analyzes HI absorption spectra of supernova remnants from Green's catalog within the VGPS survey to create a uniform catalog and determine their distances.
Contribution
It provides a new, systematically analyzed catalog of HI absorption spectra and distance estimates for SNRs in the VGPS survey.
Findings
Catalog of HI absorption spectra for SNRs created
Distances to SNRs determined using absorption spectra
Uniform analysis method applied across the sample
Abstract
The set of supernova remnants (SNR) from Green's SNR catalog which are found in the VLA Galactic Plane Survey (VGPS) are the objects considered in this study. For these SNR, we extract and analyse HI absorption spectra in a uniform way and construct a catalogue of absorption spectra and distance determinations.
