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…

An invariant energy release hierarchy in a repeating fast radio burst

X. Yang, S. B. Zhang, Y. Li +9

Fast radio bursts (FRBs) are luminous millisecond radio transients whose physical origin remains unsettled. A key diagnostic is whether their burst-energy distributions retain char…

Extreme PeV accelerator associated with GRS 1915+105

Zhen Cao, F. Aharonian, Y. X. Bai +322

Microquasars, binary systems featuring relativistic jets, have emerged as sources for particle acceleration beyond PeV energies. We present a study of the broadband -ray emissio…

An energetic dirty fireball detected in soft X-rays

C. -Y. Dai, J. Quirola-Vásquez, Y. -H. Wang +76

The collapse of massive stars drives explosions that power relativistic fireballs. If only a small amount of matter is entrained, such clean fireballs can expand with Lorentz facto…

LHAASO Detection of Ultra-High-Energy Gamma-Ray Emission toward the Giant Molecular Clouds

Zhen Cao, F. Aharonian, Y. X. Bai +310

The -ray from Giant molecular clouds (GMCs) is regarded as the most ideal tool to perform in-situ measurement of cosmic ray (CR) density and spectra in our Galaxy. We report the…

Energy calibration of LHAASO-KM2A using the cosmic ray Moon shadow

Zhen Cao, F. Aharonian, Y. X. Bai +323

We present a precise measurement of the westward, rigidity-dependent shift of the Moon's shadow using three and a half years of cosmic-ray data collected by the Kilometer Square Ar…
