Nucleosynthesis in outflows of compact objects and detection prospects of associated kilonovae

N Ekanger, M Bhattacharya… - Monthly Notices of the …, 2023 - academic.oup.com
We perform a comparative analysis of nucleosynthesis yields from binary neutron star (BNS)
mergers, black hole-neutron star (BHNS) mergers, and core-collapse supernovae (CCSNe) …

State-of-the-art collapsar jet simulations imply undetectable subphotospheric neutrinos

E Guarini, I Tamborra, O Gottlieb - Physical Review D, 2023 - APS
Mounting evidence suggests that the launching of collapsar jets is magnetically driven.
Recent general relativistic magnetohydrodynamic simulations of collapsars reveal that the …

High-energy Neutrinos from Gamma-Ray-faint Accretion-powered Hypernebulae

N Sridhar, BD Metzger, K Fang - The Astrophysical Journal, 2023 - iopscience.iop.org
Hypernebulae are inflated by accretion-powered winds accompanying hyper-Eddington
mass transfer from an evolved post-main-sequence star onto a black hole or neutron star …

GRB 221009A: Spectral signatures based on ALPs candidates

DA Rojas, S Hernández-Cadena… - The Astrophysical …, 2024 - iopscience.iop.org
GRB 221009A has posed a significant challenge to our current understanding of the
mechanisms that produce TeV photons in gamma-ray bursts (GRBs). On one hand, the Klein …

Effects of annihilation with low-energy neutrinos on high-energy neutrinos from binary neutron star mergers and rare core-collapse supernovae

G Guo, YZ Qian, MR Wu - Physical Review D, 2024 - APS
We explore the possibility that high-energy (HE) neutrinos produced from choked jets can be
annihilated with low-energy neutrinos emitted from the accretion disk around a black hole in …

Core-collapse supernovae: neutrino-dark matter phenomenology and probes of internal physics

SMD Heston - 2024 - vtechworks.lib.vt.edu
The standard model of particle physics cannot currently explain the origin of neutrino
masses and anomalies that have been observed at different experiments. One solution for …

Nuclear and particle interactions to multi-messenger signals: Core-collapse supernovae

NJ Ekanger - 2024 - vtechworks.lib.vt.edu
Multi-messenger astronomy began when a massive star underwent core collapse in a
neighboring dwarf galaxy, whose light and neutrinos reached Earth in 1987. Supernova …
