Absorption-line spectroscopy is an effective probe for cold ejecta within an SNR, provided that suitable background UV sources can be identified. For the SN 1006 remnant we have identified four such sources, in addition to the muchstudied Schweitzer-Middleditch (SM) star. We have used STIS on HST to obtain UV spectra of all four sources, to study “core samples” of the SN 1006 interior. The line...
We have reanalyzed data from observations of PSR B1706–44, SN 1006, and the Vela pulsar region made with the CANGAROO 3.8m Imaging Atmospheric Cherenkov Telescope between 1993 and 1998 in response to the results reported for these sources by the H.E.S.S. Collaboration. Although detections of TeV gamma-ray emission from these sources were claimed by CANGAROO more than 10 years ago, upper limits ...
