Although celestial sources emitting in the few tens of GeV up to a few TeV are being
investigated by imaging atmospheric Čerenkov telescope arrays such as HESS, MAGIC …

GRB 221009A was the brightest gamma-ray burst ever detected on Earth. In its early
afterglow phase, photons with exceptional energies above 10 TeV were observed by …

We conducted a comprehensive investigation of the brightest-of-all-time GRB 221009A,
using new insights from very high-energy (VHE) observations from LHAASO and a complete …

The TeV observations of GRB 221009A provided us with a unique opportunity to analyse the
contemporaneous phase in which both prompt and afterglow emissions are seen …

The LHAASO collaboration recently reported the measurement of the gamma-ray spectra of
GRB 221009A, which is the brightest burst ever, covering an energy range from 0.3 TeV to …

It has been long conjectured that a signature of quantum gravity will be Lorentz invariance
violation (LIV) that could be observed at energies much lower than the Planck scale. One …

We argue that the broad-band observations of the brightest-of-all-time (BOAT) GRB
221009A reveal a physical picture involving two jet components: a narrow (∼ 0.6 degree …

In some quantum gravity (QG) theories, Lorentz symmetry may be broken above the Planck
scale. The Lorentz invariance violation (LIV) may induce observable effects at low energies …

Abstract Large High Altitude Air Shower Observatory has detected 0.2− 13 TeV emission of
GRB 221009A within 2000 s since the trigger. Here we report the detection of a 400 GeV …

GRB 221009A has posed a significant challenge to our current understanding of the
mechanisms that produce TeV photons in gamma-ray bursts (GRBs). On one hand, the Klein …
