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…

Ultra-high-energy -ray imprints from PeV particles accelerated by supernova remnants

Zhen Cao, F. Aharonian, Y. X. Bai +320

The quest for the origin of cosmic ray (CRs) is a fundamental issue in astrophysics. Shocks of supernova remnants (SNRs) have been considered as the dominant contributors to Galact…

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…
