Title: New Insights into the Physics of Supernovae and their Remnants: A Comprehensive X-ray Study of SN 1572

Abstract: In this colloquium I will present some new findings from Chandra and XMM-Newton data on the remnant of the supernova (SN) observed by Tycho Brahe in 1572, which is widely believed to have been of Type Ia origin. Studies of the Tycho supernova remnant (SNR) at the current epoch address aspects of SN Ia physics, the evolution of young SNRs, and cosmic ray acceleration at high Mach-number shocks.
