DESCRIPTION:Accurately modeling neutrino flavor oscillations in global sim
 ulations of core-collapse supernovae or neutron star mergers remains a maj
 or challenge\, albeit a potentially crucial one for making reliable predic
 tions. Indeed\, it is now widely recognized that flavor instabilities\, 
 in which neutrino distributions computed in classical transport frameworks
  can be dramatically reshaped by flavor conversion\, are ubiquitous in suc
 h environments.\nIn this talk\, I will describe recent progress in underst
 anding and modeling these instabilities\, focusing on the development of s
 ubgrid models of neutrino flavor transformation. In this approach\, insigh
 ts from detailed studies of local quantum neutrino transport are used to f
 ormulate effective prescriptions that modify classical neutrino distributi
 ons\, enabling their incorporation into large-scale simulations. Over the
  past year\, the first supernova and neutron star merger simulations inclu
 ding these subgrid treatments have been performed\, a key step toward full
 y incorporating neutrino physics into such models and assessing its wide-r
 anging implications.\n\nhttps://indico.ific.uv.es/event/8590/
