The unstable null circular geodesic features the spherically symmetrical asymptotically flat black hole
Yuxuan Shi
We analyse the massless particles orbiting a spherically symmetric, asymptotically flat black hole with a radius equal to the photon sphere and a circular geodesic. Asymptotic obse…

The gamma-ray burst arising from neutrino pair annihilation in the static and spherically symmetric black-hole-like wormholes
Yuxuan Shi, Hongbo Cheng
We look into the neutrino-antineutrino pair () annihilation in the Damour-Solodukhin wormhole spacetime whose metric component involves a shift…
