REVERSE-SHOCK IN TYCHO’S SUPERNOVA REMNANT
REVERSE-SHOCK IN TYCHO’S SUPERNOVA REMNANT
Thermal X-ray emission from young supernova remnants (SNRs) is usually dominated by the emission lines of the supernova (SN) ejecta, which are widely believed being crossed and thus heated by the inwards propagating reverse shock (RS). Previous works using imaging X-ray data have shown that the ejecta are heated by …
