The role of jets before, during, and after explosions and in powering ILOTs

I will describe recent results on the role of jets in exploding core collapse supernovae (CCSNe) and in powering Intermediate Luminosity Optical Transients (ILOTs), and will compare the results with the most recent observations and with other theoretical studies. I will discuss new ideas of processes that become possible by jets, such as the jittering jets explosion mechanism of massive stars aided by neutrino heating, the formation of Type IIb CCSNe by the Grazing Envelope Evolution (GEE), and common envelope jets supernovae (CEJSNe).
