DESCRIPTION:Speakers: Matteo Bugli (CEA Saclay/DRF/IRFU/DAp UMR AIM\, Fran
 ce)\n\nLong gamma-ray bursts (GRBs) are considered to be associated\, in g
 eneral\, with the gravitational collapse of massive stars having fast-rota
 ting cores and intense large-scale magnetic fields. The so-called magneto-
 rotational mechanism allows the onset of extremely powerful core-collapse 
 supernovae that can account for the extraordinarily energetic ejecta requi
 red to produce a GRB.\nIn this seminar I will present recent developments 
 in the numerical modeling of such extreme explosive events\, showing their
  predictions in terms of explosion dynamics\, multi-messenger emission\, a
 nd explosive nucleosynthetic yields. In particular\, I will highlight the 
 role played by different magnetic field topology\, rotation rates\, and eq
 uations of state in shaping the multi-faceted properties of magneto-rotati
 onal core-collapse supernovae\, along with the challenges we currently fac
 e in describing the associated jet through and beyond the progenitor star.
