LHAASO-WCDA observed a 5 days TeV-delayed flaring event in blazar 1ES 1959+650
Zhen Cao, F. Aharonian, Y. X. Bai +339
We report a day-scale hard lag between GeV and TeV -ray emission from the HBL 1ES~1959+650 in early 2024. Since the LHAASO-WCDA real-time monitoring system began operation in la…
Generation of TeV Photons by PeV Neutrinos in Dense Astrophysical Environments
Jun-Chen Wang, Hanlin Song, Hao Li +2
Recent observations by IceCube and KM3Net of PeV-scale ultra-high-energy (UHE) neutrinos, together with detections of TeV-PeV photons from various sources such as the Crab Nebula,…
Anisotropic Particle Transport from a Pulsar Wind Nebula Revealed by Einstein Probe and LHAASO
Zhen Cao, F. Aharonian, Y. X. Bai +339
Pulsar wind nebulae (PWNe) are major cosmic ray accelerators, yet the mechanisms transporting high-energy particles into the interstellar medium remain elusive. Building on the LHA…
Correlation between Ultrahigh-Energy Neutrino KM3-230213A and Gamma-Ray Bursts
Ruiqi Wang, Bo-Qiang Ma
The KM3NeT Collaboration reported the detection of a neutrino, designated as KM3-230213A, with a reconstructed energy peaking at 220 PeV and equatorial coordinates (J2000) of RA=$9…
Testing the strong equivalence principle with multimessenger binary neutron star mergers
Jie Zhu, Hanlin Song, Zhenwei Lyu +5
The constancy of the gravitational constant is a cornerstone of the strong equivalence principle and of general relativity, yet its possible temporal variation remains a key ta…
An extreme particle accelerator powered by pulsar PSR J1849-0001
The LHAASO Collaboration
Pulsar wind nebulae (PWNe) are bubbles of relativistic particles, powered by the rotational energy loss of the central pulsars. The Crab Nebula, powered by the Milky Way's most ene…
Constraints on birefringence-free photon theory within standard-model extension
Zhi Xiao, Hanlin Song, Bo-Qiang Ma
Constraints on the birefringence-free subset of Lorentz-violating (LV) operators are derived using 14 GRB photons in the GeV-band. These constraints target the isotropic $c_{(I)00}…
Carpet-3 300 TeV Photon Event as an Evidence for Lorentz Violation
Hanlin Song, Bo-Qiang Ma
The detection by the Carpet-3 Group of a 300 TeV photon, observed 4536 seconds after the prompt emission of the historic gamma-ray burst GRB 221009A, provides unprecedented opportu…
Monte Carlo simulation of GRB data to test Lorentz-invariance violation
Hanlin Song, Bo-Qiang Ma
Lorentz-invariance violation (LV) at energy scales approaching the Planck regime serves as a critical probe for understanding quantum gravity phenomenology. Astrophysical observati…
Examining Lorentz invariance violation with three remarkable GRB photons
Hanlin Song, Bo-Qiang Ma
Lorentz invariance violation in photons can be quantified by measuring the difference in arrival times between high- and low-energy photons originating from gamma-ray bursts (GRBs)…
Lorentz Invariance Violation from Gamma-Ray Bursts
Hanlin Song, Bo-Qiang Ma
Lorentz invariance violation (LV) is examined through the time delay between high-energy and low-energy photons in gamma-ray bursts (GRBs). Previous studies determined the LV energ…
Direct evidence for preburst stage of gamma-ray burst from GRB 221009A data
Qing Liu, Hanlin Song, Bo-Qiang Ma
Previous research on Lorentz invariance violation in photons from gamma-ray bursts (GRBs) suggested a scenario where multi-GeV photons could be emitted before lower-energy photons…
Energy-dependent intrinsic time delay of gamma-ray bursts on testing Lorentz invariance violation
Hanlin Song, Bo-Qiang Ma
High-energy photons of gamma-ray bursts (GRBs) might be emitted at different intrinsic times with energy dependence at the source. In this letter, we expand the model from previous…
