Revisiting magnon bound states: ferro-antiferromagnetic square-lattice model
Cesar A. Gallegos, A. L. Chernyshev
A comprehensive analysis of pairing and bound states of magnons in the Heisenberg square-lattice ferro-antiferromagnetic model is presented. We highlight…
Magnetized Shocks Mediated by Radiation from Leptonic and Hadronic Processes
Shunke Ai, Irene Tamborra
Shocks in astrophysical transients are key sites of particle acceleration. If the shock upstream is optically thick, radiation smoothens the velocity discontinuity at the shock (ra…
Multimessenger Prospects for Low-Luminosity Gamma-Ray Bursts: Joint Neutrino and X-Ray Observations
Wenkang Lian, He Gao, Shunke Ai +1
Low--luminosity gamma-ray bursts (LLGRBs) are promising candidates for high-energy neutrinos, yet no coincident neutrino events have been detected so far. Recent advances in X-ray…
Constraining the Properties of GRB Accreting Magnetar with Evolutionary Effects Using \emph{Swift}/XRT Data
Lin Lan, He Gao, Litao Zhao +6
A newly born millisecond magnetar has been proposed as one possible central engine of some long gamma-ray bursts (LGRBs) with X-ray plateau. In this work, we used a universal corre…
Constrain magnetar parameters by taking into account the evolutionary effects of radius and moment of inertia with \emph{Swift}/XRT data
Lin Lan, He Gao, Shunke Ai +5
A newly born millisecond magnetar has been proposed as one possible central engine of some GRBs with X-ray plateau emission. In this work, we systematically analyzed the Swift/XRT…
A 50 s quasi-periodic oscillation in the early X-ray afterglow of GRB 220711B
H. Gao, W. -H. Lei, S. Xiao +19
It is generally believed that long duration gamma-ray bursts (GRBs) originate from the core collapse of rapidly spinning massive stars and at least some of them are powered by hype…
