The Effect of Mass Loss and Convective Overshooting on the Pre-Collapse Structure, Composition, and Neutrino Emission of Red Supergiants
McKenzie A. Myers, Claire B. Campbell, Kelly M. Patton +6
Prior to core collapse, the neutrino emission from red supergiants (RSGs) is so large that a nearby (kpc) RSG will become visible in current and near-future neutrino det…
Neutrino transport and flavor instabilities in a post-merger disk
Erick Urquilla, Swapnil Shankar, Debraj Kundu +6
Neutron star mergers are multimessenger sources whose dynamics and signals depend critically on neutrinos and their flavor transformations. We investigate whether fast and collisio…
Neutrino flavor instabilities in neutron star mergers with moment transport: Slow, fast, and collisional modes
Julien Froustey, Francois Foucart, Christian Hall +5
Determining where, when, and how neutrino flavor oscillations must be included in large-scale simulations of hot and dense astrophysical environments is an enduring challenge that…
Data-driven core collapse supernova multilateration with first neutrino events
Farrukh Azfar, Jeff Tseng, Marta Colomer Molla +8
A Galactic core-collapse supernova (CCSN) is likely to be observed in neutrino detectors around the world minutes to hours before the electromagnetic radiation arrives. The SNEWS2.…
Turbulence in Core-Collapse Supernovae
David Calvert, Michael Redle, Bibek Gautam +4
It is understood in a general sense that turbulent fluid motion below the shock front in a core-collapse supernova stiffens the effective equation of state of the fluid and aids in…
Advection Algorithms for Quantum Neutrino Moment Transport
Evan Grohs, Sherwood Richers, Julien Froustey +3
Neutrino transport in compact objects is an inherently challenging multi-dimensional problem. This difficulty is compounded if one includes flavor transformation -- an intrinsicall…
