Neutrino-Neutron Scattering Opacities in Supernova Matter
Gang Guo, Gabriel Martínez-Pinedo, Meng-Ru Wu
We compute the static density and spin structure factors in the long wavelength limit for pure neutron matter at subsaturation densities relevant to core-collapse supernovae within…
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…

Yu An, Meng-Ru Wu, Gang Guo +3
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…
Signature of Collapsars as Sources for High-energy Neutrinos and -process Nuclei
Gang Guo, Yong-Zhong Qian, Meng-Ru Wu
If collapsars are sources for both high-energy (HE) neutrinos and -process nuclei, the profuse low-energy antineutrinos from -decay of the newly-synthesized nuclei can annihi…

A. Sieverding, E. Rrapaj, G. Guo +1
We study the effects of additional cooling due to the emission of a dark matter candidate particle, the dark photon, on the final phases of the evolution of a star an…

Andreas Bauswein, Gang Guo, Jr-Hua Lien +2
We estimate the long-lasting gravitational wave (GW) emission of compact dark objects following a binary neutron-star (NS) merger. We consider compact dark objects, which initially…
Muonization of supernova matter
Tobias Fischer, Gang Guo, Gabriel Martínez-Pinedo +2
The present article investigates the impact of muons on core-collapse supernovae, with particular focus on the early muon neutrino emission. While the presence of muons is well und…
Elastic and Inelastic Scattering of Cosmic-Rays on Sub-GeV Dark Matter
Gang Guo, Yue-Lin Sming Tsai, Meng-Ru Wu +1
We revisit the signatures from collisions of cosmic-rays on sub-GeV dark matter (DM) in the Milky Way. In addition to the upscattered DM component that can be probed by existing DM…
Charged-Current Muonic Reactions in Core-Collapse Supernovae
Gang Guo, Gabriel Martínez-Pinedo, Andreas Lohs +1
The steady advance in core-collapse supernova simulations requires a more precise description of neutrino processes in hot and dense matter. In this work, we study the rates of cha…

The direct detection of particle dark matter through its scattering with nucleons is of fundamental importance to understand the nature of DM. In this work, we propose that the hig…
Neutrino Production Associated with Late Bumps in Gamma-Ray Bursts and Potential Contribution to Diffuse Flux at IceCube
Gang Guo, Yong-Zhong Qian, Meng-Ru Wu
IceCube has detected many TeV--PeV neutrinos, but their astrophysical origins remain largely unknown. Motivated by the observed late-time X-ray/optical bumps in some gamma-ray burs…

We assess the potential of using presupernova neutrino signals at the Jiangmen Underground Neutrino Observatory (JUNO) to probe the yet-unknown neutrino mass hierarchy. Using model…
Improved axion emissivity from a supernova via nucleon-nucleon bremsstrahlung
Pierluca Carenza, Tobias Fischer, Maurizio Giannotti +3
The most efficient axion production mechanism in a supernova (SN) core is the nucleon-nucleon bremsstrahlung. This process has been often modeled at the level of the vacuum one-pio…
