Correlation of Supernova Remnant Masers and Gamma-Ray Sources (2009)
Hewitt, John W., Yusef-Zadeh, Farhad, Wardle, Mark
Supernova remnants interacting with molecular clouds are potentially exciting systems in which to detect evidence of cosmic ray acceleration. Prominent gamma-ray emission is produced via the decay of...
Spitzer Observations of Molecular Hydrogen in Interacting Supernova Remnants (2009)
Hewitt, John W., Rho, Jeonghee, Andersen, Morten, Reach, William T.
With Spitzer IRS, we have obtained sensitive low-resolution spectroscopy from 5 to 35 μm for six supernova remnants (SNRs) that show evidence of shocked molecular gas: Kes 69, 3C 396, Kes 17,...
Discovery of New Interacting Supernova Remnants in the Inner Galaxy (2009)
Hewitt, John W., Yusef-Zadeh, Farhad
OH(1720 MHz) masers are excellent signposts of interaction between supernova remnants(SNRs) and molecular clouds. Using the GBT and VLA we have surveyed 75 SNRs and six candidates for maser emission....

GBT Observations of IC 443: the Nature of OH(1720 MHz) Masers and OH Absorption (2006)
Hewitt, John W., Yusef-Zadeh, Farhad, Wardle, Mark, Roberts, Douglas A., Kassim, Namir E.
We present results of spectral line observations of the ground state transitions of hydroxyl(OH) toward supernova remnant IC 443 carried out with the Green Bank Telescope. At a spatial resolution of...
