The formalism of energy conservation during particle decay in the Kerr spacetime
Shurui Zhang, Remo Ruffini
We derive a compact, covariant expression for the relative Lorentz factor of two particles in curved spacetime and apply it to particle decay in Kerr spacetime. This allows us to s…
An Intertwined Short and Long GRB with 4-minute Separation
Liang Li, Yu Wang, Bing Zhang +19
Gamma-ray bursts (GRBs), the most energetic transients in the Universe, are traditionally classified into long-duration ( s) and short-duration ( s) events, ass…
Energy Loss of Newborn Magnetars by Schwinger Process
Chul Min Kim, Sang Pyo Kim, Remo Ruffini +2
We investigate electron--positron pair creation through the Schwinger process in newborn magnetars with millisecond spin periods and surface dipole fields close to or above the QED…
LVK S241125n: Massive Binary Black Hole Merger Produces Gamma Ray Burst in Active Galactic Nucleus Disk
Shu-Rui Zhang, Yu Wang, Ye-Fei Yuan +6
Recently, the gravitational-wave (GW) event S241125n, detected by LIGO/Virgo/KAGRA (LVK), has been reported to coincide with a candidate detected by Swift-BAT/GUANO and an X-ray ca…
Can the central compact object in HESS J1731--347 be indeed the lightest neutron star observed?
Shu-Rui Zhang, Jorge A. Rueda, Rodrigo Negreiros
The exceptionally low mass of for the central compact object (CCO) XMMU J173203.3 -- 344518 (XMMU J1732) in the supernova remnant (SNR) HESS J1731 -…
On the single versus the repetitive Penrose process in a Kerr black hole
Remo Ruffini, Mikalai Prakapenia, Hernando Quevedo +1
Extracting the rotational energy from a Kerr black hole (BH) is one of the crucial topics in relativistic astrophysics. Here, we give special attention to the Penrose ballistic pro…
