SUMMARY:Astronomy & Astrophysics Seminar
DESCRIPTION:
Speaker: Sherwood Richers\n
Speaker's Institution:
Caltech\n
Seminar Title: Monte Carlo Neutrino
Transport in Supernovae and GRBs\n
Neutrino
interactions dominate the energetics of core-collapse
supernovae (CCSNe) and\n
determine
the composition of the matter ejected from CCSNe
and gamma-ray bursts (GRBs).\n
Three dimensional
(3D) CCSN and neutron star merger simulations
are rapidly improving, but\n
still suffer
from approximate treatments of neutrino transport
that cripple their reliability and\n
realism. I use my relativistic time-independent
Monte Carlo neutrino transport code SEDONU
to\n
evaluate the effectiveness of leakage, moment,
and discrete ordinate schemes in both
of these\n
scenarios, and calculate neutrino pair
annihilation rates to try to explain the
jet launching\n
mechanism of GRBs. I also developed
a relativistic extension to the Random
Walk\n
approximation that greatly accelerates
convergence in diffusive regimes, making full-domain\n
simulations
possible. All of these improvements
will culminate in a coupled Monte
Carlo - two\n
moment transport scheme efficient
enough to incorporate into the to-date most
accurate global\n
three-dimensional GRMHD simulations.\n\n
