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…
An energetic dirty fireball detected in soft X-rays
C. -Y. Dai, J. Quirola-Vásquez, Y. -H. Wang +76
The collapse of massive stars drives explosions that power relativistic fireballs. If only a small amount of matter is entrained, such clean fireballs can expand with Lorentz facto…
Observations of the Fermi bubbles and the Galactic center excess with the DArk Matter Particle Explorer
F. Alemanno, Q. An, P. Azzarello +145
The DArk Matter Particle Explorer (DAMPE) is a space-borne high-energy particle detector that surveys the -ray sky above with a peak acceptance of $\sim 0.2~\rm…
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…
Observation of a spectral hardening in cosmic ray boron spectrum with the DAMPE space mission
DAMPE Collaboration, F. Alemanno, C. Altomare +143
Secondary cosmic ray fluxes are important probes of the propagation and interaction of high-energy particles in the Galaxy. Recent measurements of primary and secondary cosmic ray…
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…
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…
Measurement of the cosmic p+He energy spectrum from 50 GeV to 0.5 PeV with the DAMPE space mission
DAMPE Collaboration, F. Alemanno, C. Altomare +152
Recent observations of the light component of the cosmic-ray spectrum have revealed unexpected features that motivate further and more precise measurements up to the highest energi…
The X-ray afterglow of GRB 081109A: clue to the wind bubble structure
Z. P. Jin, D. Xu, S. Covino +4
We present the prompt BAT and afterglow XRT data of Swift-discovered GRB081109A up to ~ 5\times 10^5 sec after the trigger, and the early ground-based optical follow-ups. The tempo…
