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…
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-…
Stringent Tests of Lorentz Invariance Violation from LHAASO Observations of GRB 221009A
The LHAASO Collaboration, Zhen Cao, F. Aharonian +283
On October 9, 2022, the Large High Altitude Air Shower Observatory (LHAASO) reported the observation of the very early TeV afterglow of the brightest-of-all-time GRB 221009A, recor…
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…
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 cosm…
Monitoring the daily variation of Sun-Earth magnetic fields using galactic cosmic rays
The LHAASO Collaboration, C. W. Jiang, Y. Yang
The interplanetary magnetic field (IMF) between the Sun and Earth is an extension of the solar magnetic field carried by the solar wind into interplanetary space. Monitoring variat…
