Discovery of Molecular Shells Associated with Supernova Remnants . ( I )
Supernova remnant (SNR) Kes 69 is morphologically characterized by the brightened radio, infrared, and X-ray emission on the southeastern rim, with the 1720 MHz OH masers detected in northeastern and southeastern regions at various LSR velocities. We have performed a millimeter observation in CO and HCO lines toward Kes 69. From the northeastern compact maser region, the CO and CO emission’s pe...
متن کاملDiscovery of Molecular Shells Associated with Supernova Remnants . ( Ii )
The young composite supernova remnant (SNR) Kesteven 75, with a pulsar wind nebula at its center, has an unusual morphology with a bright southern half-shell structure in multiwavelengths. The distance to Kes 75 has long been uncertain. Aiming to address these issues, we have made millimeter spectroscopic observations of the molecular gas toward the remnant. The VLSR ∼ 83– 96 km s molecular clo...
متن کاملShell-type Supernova Remnants
The role of Supernova Remnants (SNRs) for the production of the Galactic Cosmic Rays is reviewed from the point of view of theory and very high energy gamma-ray experiments. The point is made that theory can describe young SNRs very well, if the evidence from the synchrotron emission is used to empirically determine several parameters of the theory, and thus theory can predict the relative cont...
متن کاملSupernova Remnants and GLAST
It has long been speculated that supernova remnants represent a major source of cosmic rays in the Galaxy. Observations over the past decade have ceremoniously unveiled direct evidence of particle acceleration in SNRs to energies approaching the knee of the cosmic ray spectrum. Nonthermal X-ray emission from shell-type SNRs reveals multi-TeV electrons, and the dynamical properties of several SN...
متن کاملObservations of Supernova Remnants with VERITAS
The study of shell-type supernova remnants is a key science focus for the VERITAS TeV telescope array. Supernova remnants (SNRs) are widely considered to be the strongest candidate for the source of cosmic rays below the knee around 10 eV. This presentation will highlight new VERITAS results including new measurements of the spectra of Cas A and IC 443. These results and their implications for ...
