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…
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…
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…
Photon-ALP beam propagation from Mrk 501
L. J. Dong, Y. G. Zheng, S. J. Kang +1
The very high energy (VHE, E ) -ray observations offer a possibility of indirectly detecting the presence of axion-like particles (ALPs). The paper focuse…
Evidence for particle acceleration approaching PeV energies in the W51 complex
The LHAASO Collaboration, Zhen Cao, F. Aharonian +284
The -ray emission from the W51 complex is widely acknowledged to be attributed to the interaction between the cosmic rays (CRs) accelerated by the shock of supernova remnant (SN…
Data quality control system and long-term performance monitor of the LHAASO-KM2A
Zhen Cao, F. Aharonian, Axikegu +282
The KM2A is the largest sub-array of the Large High Altitude Air Shower Observatory (LHAASO). It consists of 5216 electromagnetic particle detectors (EDs) and 1188 muon detectors (…
A time-dependent particle acceleration and emission model: Understanding the particle spectral evolution and blazar flares
Y. G. Zheng, S. J. Kang, C. Y. Yang +1
The jets of blazars are renowned for their multi-wavelength flares and rapid extreme variability; however, there are still some important unanswered questions about the physical pr…
Chandra Observation of PWN G16.73+0.08 in SNR G16.7+0.1
H. -K. Chang, S. -F. Chung, C. -Y. Yang +1
We present X-ray observations of PWN G16.73+0.08/SNR G16.7+0.1 using archival data of {\it Chandra} ACIS. The X-ray emission peak location of this pulsar wind nebula is found to be…
Polarimetric Analysis of the Long Duration Gamma Ray Burst GRB 160530A With the Balloon Borne Compton Spectrometer and Imager
Alexander W. Lowell, Steven E. Boggs, Jeng-Lun Chiu +11
A long duration gamma-ray burst, GRB 160530A, was detected by the Compton Spectrometer and Imager (COSI) during the 2016 COSI Super Pressure Balloon campaign. As a Compton telescop…
