Equatorially Asymmetric Magnetic Fields and Their Impact on Black Hole Accretion Dynamics
Ishika Palit, Indu Kalpa Dihingia, Yosuke Mizuno +1
We investigate the impact of equatorial asymmetry in the magnetic field geometry on accretion dynamics around a spinning black hole using axisymmetric general relativistic magnetoh…
Exploring the Role of Vector Potential and Plasma- in Jet Formation from Magnetized Accretion Flows
Ishika Palit, Miles Angelo Paloma Sodejana, Hsiang-Yi Karen Yang
In this work, we investigate how the choice of initial vector potential and plasma parameters influences the development of accretion columns and jet formation in magnetized accret…
Occurrence of fast neutrino flavor conversions in QCD phase-transition supernovae
Zewei Xiong, Meng-Ru Wu, Noshad Khosravi Largani +2
Core-collapse supernovae undergoing a first-order quantum chromodynamics (QCD) phase transition experience the collapse of the central proto-neutron star that leads to a second bou…
Flavor Equilibration of Supernova Neutrinos: Exploring the Dynamics of Slow Modes
Ian Padilla-Gay, Heng-Hao Chen, Sajad Abbar +2
Neutrinos experience collective flavor conversion in extreme astrophysical environments such as core-collapse supernovae (CCSNe). One manifestation of collective conversion is slow…
Neutrino Oscillations in Core-Collapse Supernovae and Neutron Star Mergers
Lucas Johns, Sherwood Richers, Meng-Ru Wu
Accurate neutrino transport is crucial for reliably modeling explosive astrophysical events like core-collapse supernovae (CCSNe) and neutron star mergers (NSMs). However, in these…
Actinide signatures in low electron fraction kilonova ejecta
Quentin Pognan, Meng-Ru Wu, Gabriel Martínez-Pinedo +4
Neutron star (NS) mergers are known to produce heavy elements through rapid neutron capture (r-process) nucleosynthesis. Actinides are expected to be created solely by the r-proces…
Evolution and the quasistationary state of collective fast neutrino flavor conversion in three dimensions without axisymmetry
Manu George, Zewei Xiong, Meng-Ru Wu +1
We investigate in this work the evolution of the collective fast neutrino flavor conversion (FFC) in a three dimensional (3D) cubic box with periodic boundary condition for three d…
Fast neutrino flavor conversions in a supernova: Emergence, evolution, and effects
Zewei Xiong, Meng-Ru Wu, Manu George +4
Fast flavor conversions (FFCs) of neutrinos, which can occur in core-collapse supernovae (CCSNe), are multiangle effects. They depend on the angular distribution of the neutrino's…
Effects of Annihilation with Low-Energy Neutrinos on High-Energy Neutrinos from Binary Neutron Star Mergers and Rare Core-Collapse Supernovae
Gang Guo, Yong-Zhong Qian, Meng-Ru Wu
We explore the possibility that high-energy (HE) neutrinos produced from choked jets can be annihilated with low-energy (LE) neutrinos emitted from the accretion disk around a blac…
Neutrinos and nucleosynthesis of elements
Tobias Fischer, Gang Guo, Karlheinz Langanke +3
Neutrinos are known to play important roles in many astrophysical scenarios from the early period of the big bang to current stellar evolution being a unique messenger of the fusio…
Evaluating approximate asymptotic distributions for fast neutrino flavor conversions in a periodic 1D box
Zewei Xiong, Meng-Ru Wu, Sajad Abbar +3
The fast flavor conversions (FFCs) of neutrinos generally exist in core-collapse supernovae and binary neutron-star merger remnants, and can significantly change the flavor composi…
Recent Progress in Modeling the Macro- and Micro-Physics of Radio Jet Feedback in Galaxy Clusters
Martin A. Bourne, Hsiang-Yi Karen Yang
Radio jets and the lobes they inflate are common in cool-core clusters and are known to play a critical role in regulating the heating and cooling of the intracluster medium (ICM).…
R-process beta-decay neutrino flux from binary neutron star mergers and collapsars

This study investigates the antineutrinos production by -decay of -process nuclei in two astrophysical sites that are capable of producing gamma-ray bursts (GRBs): binary neu…
Dark Stars and Gravitational Waves: Topical Review
Kilar Zhang, Ling-Wei Luo, Jie-Shiun Tsao +2
Motivated by recent observations of compact binary gravitational wave events reported by LIGO/Virgo/KAGRA, we review the basics of dark and hybrid stars and examine their probabili…
Evolution and feedback of AGN Jets of different Cosmic-ray Composition
Yen-Hsing Lin, H. -Y. Karen Yang, Ellis R. Owen
Jet feedback from active galactic nuclei (AGN) is one of the most promising mechanisms for suppressing cooling flows in cool-core clusters. However, the composition of AGN jets and…
Evolution of collisional neutrino flavor instabilities in spherically symmetric supernova models
Zewei Xiong, Meng-Ru Wu, Gabriel Martínez-Pinedo +4
We implement a multi-group and discrete-ordinate neutrino transport model in spherical symmetry which allows to simulate collective neutrino oscillations by including realistic col…

We report measurements of the gravitationally lensed secondary image -- the first in an infinite series of so-called "photon rings" -- around the supermassive black hole M87* via s…
Evolution of Main-Sequence-like Surviving Companions in Type Ia Supernova Remnants
Shiau-Jie Rau, Kuo-Chuan Pan
Recent theoretical and numerical studies of Type Ia supernova explosion within the single-degenerate scenario suggest that the non-degenerate companions could survive during the su…
