Observational confirmations are mandatory to understand the explosion mechanism of core-collapse supernovae completely. Direct observations will be done by neutrinos and gravitational waves for a future supern ova that will happen in Milky Way or very nearby galaxies. Such a near by supernova should occur in the future\, but the supernova rate is ro ughly 1 event per century per galaxy. The youngest supernova found in Milky Way is Cassiopeia A\, whose age is about 350 yrs old. The younge st supernova in Large Magellanic Cloud is SN1987A which is 35 yrs old. Therefore\, we cannot predict when the next nearby supernova will hap pen. In this talk\, I would like to present our unique approach to fin ding observational evidence of the explosion mechanism of core-collaps e supernovae in young supernova remnants. We did 3-dimensional hydro s imulations that covered from supernova explosion phase to the supernov a remnant phase. Such multi-D simulations with a wide range of scales (in time and length) have never been done before. We could demonstrate that such simulations are possible thanks to excellent international collaborations. This talk will mainly present a detailed comparison be tween our simulations and SN1987A. I will shortly show that such compa rison is meaningful for Cassiopeia A and Type Ia supernova remnants\, too. \n \n \nJoin Zoom Meeting \nhttps://berkeley.zoom.us/j/9123071454 7 \n \nMeeting ID: 912 3071 4547 \n \n URL:https://www.physics.wisc.edu/events/?id=6822 END:VEVENT END:VCALENDAR
