LHAASO observation of Mrk 421 during 2021 March - 2024 March: a comprehensive VHE catalog of multi-timescale outbursts and its time average behavior

The LHAASO Collaboration, Zhen Cao, F. Aharonian +321

The Large High Altitude Air Shower Observatory (LHAASO) monitors sources within its field of view for up to 7 hours daily, achieving a duty cycle exceeding 98% and an annual point-…

Cygnus X-3: A variable petaelectronvolt gamma-ray source

The LHAASO Collaboration, Zhen Cao, F. Aharonian +324

We report the discovery of variable -rays up to petaelectronvolt from Cygnus X-3, an iconic X-ray binary. The -ray signal was detected with a statistical significance of appr…

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…

All-sky search for individual Primordial Black Hole bursts with LHAASO

Zhen Cao, F. Aharonian, Y. X. Bai +311

Primordial Black Holes~(PBHs) are hypothetical black holes with a wide range of masses that formed in the early universe. As a result, they may play an important cosmological role…
