Distances to supernova remnants G20.4 + 0.1, G24.7 - 0.6, and G28.6 - 0.1 and new molecular cloud associations.


Abstract (from CDS):

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 VLA (Very Large Array) Galactic Plane Survey for extraction of H I absorption spectra. Analysing H I absorption spectra, 13CO emission spectra, and H I and 13CO channel maps, kinematic velocities (or their limits) to the three SNRs were calculated. The three SNRs are probably associated with molecular clouds and the new distance to G20.4 + 0.1, G24.7 - 0.6, and G28.6 - 0.1 are 7.8 ± 0.5 kpc, 3.8 ± 0.2 kpc, and 9.6 ± 0.3 kpc, respectively.
