The Extended Ultrahigh-energy Gamma-Ray Emission in the Vicinity of PSR J2238+5903

Zhen Cao, F. Aharonian, Y. X. Bai +324

We present a comprehensive analysis of the recently discovered TeV gamma-ray source, LHAASO J2238+5900. Based on data collected from the LHAASO, our fitting results suggest that th…

Transient Large-Scale Anisotropy in TeV Cosmic Rays due to an Interplanetary Coronal Mass Ejection

Zhen Cao, F. Aharonian, Y. X. Bai +309

Large- or medium-scale cosmic ray anisotropy at TeV energies has not previously been confirmed to vary with time. Transient anisotropy changes have been observed below 150 GeV, esp…

Precise measurements of the cosmic ray proton energy spectrum in the "knee'' region

The LHAASO Collaboration, Zhen Cao, F. Aharonian +310

We report the high-purity identification of cosmic-ray (CR) protons and a precise measurement of their energy spectrum from 0.15 to 12 PeV using the Large High Altitude Air Shower…

Study of Ultra-High-Energy Gamma-Ray Source 1LHAASO J0056+6346u and Its Possible Origins

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

We report a dedicated study of the newly discovered extended UHE -ray source 1LHAASO J0056+6346u. Analyzing 979 days of LHAASO-WCDA data and 1389 days of LHAASO-KM2A data, we ob…

Constraining the Cosmic-ray Energy Based on Observations of Nearby Galaxy Clusters by LHAASO

The LHAASO Collaboration, Zhen Cao, F. Aharonian +323

Galaxy clusters act as reservoirs of high-energy cosmic rays (CRs). As CRs propagate through the intracluster medium, they generate diffuse -rays detectable by arrays such as LH…

An Enigmatic PeVatron in an Area around HII Region G35.60.5

The LHAASO Collaboration, Zhen Cao, F. Aharonian +294

Identifying Galactic PeVatrons (PeV particle accelerators) from the ultra-high-energy (UHE, >100 TeV) -ray sources plays a crucial role in revealing the origin of Galactic cosmi…

Observation of the -ray Emission from W43 with LHAASO

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

In this paper, we report the detection of the very-high-energy (VHE, ) and ultra-high-energy (UHE, ) -ray emissions from th…

An Ultrahigh-energy -ray Bubble Powered by a Super PeVatron

The LHAASO Collaboration, Z. Cao, F. Aharonian +277

We report the detection of a -ray bubble spanning at least 100 in ultra high energy (UHE) up to a few PeV in the direction of the star-forming region Cygnus X, implyi…

Exploring Lorentz Invariance Violation from Ultra-high-energy Gamma Rays Observed by LHAASO

Zhen Cao, F. Aharonian, Q. An +268

Recently the LHAASO Collaboration published the detection of 12 ultra-high-energy gamma-ray sources above 100 TeV, with the highest energy photon reaching 1.4 PeV. The first detect…
