Possibility of Month-scale Quasi-periodic Oscillations in the Gamma-ray Light Curve of OP 313
Sandeep Kumar Mondal, Shubham Kishore, Alok C. Gupta +1
In this work, we report evidence suggesting the potential future detection of a month-scale quasi-periodic oscillation (QPO) in the gamma-ray light curve of OP 313. We analysed alm…
Energy-Dependent Shifts of Medium-Scale Anisotropies in Very-High-Energy Cosmic Rays Observed by LHAASO-KM2A
The LHAASO collabration, Zhen Cao, F. Aharonian +310
Small deviations from isotropy in the arrival directions of Galactic cosmic rays serve as a unique probe of the local magnetic environment. In this Letter, we report observations o…
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…
A Self-Consistent Model of the Ultra High-Energy Gamma-Ray Emission of Pulsar Wind Nebulae: Insights from LHAASO and ATNF Catalogs
Samy Kaci, Gwenael Giacinti, Dmitri Semikoz
Pulsar wind nebulae (PWNe) are the dominant Ultra-high-energy (UHE) gamma-ray sources in the LHAASO catalog suggesting that they are the dominant leptonic PeVatrons in our Galaxy.…
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…
A Giant Peanut-shaped Ultra-High-Energy Gamma-Ray Emitter Off the Galactic Plane
Zhen Cao, Felix Aharonian, Yunxiang Bai +312
Ultra-high-energy (UHE), exceeding 100 TeV (10^12 electronvolts), γ-rays manifests extreme particle acceleration in astrophysical sources. Recent observations by γ-ray telescopes,…
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…
Microquasars as the major contributors to Galactic cosmic rays around the "knee"
Samy Kaci, Gwenael Giacinti, Felix Aharonian +1
Recently, LHAASO detected a gamma-ray emission extending beyond from 4 sources associated to powerful microquasars. We propose that such sources are the main Galact…
Discovery of diffuse gamma-ray emission in the vicinity of G172.8+1.5: An old supernova remnant with different turbulence properties
Yuan Li, Gwenael Giacinti, Siming Liu
We report the detection of high-energy -ray emission in the vicinity of G172.8+1.5, which is debated as a Supernova remnant (SNR) or an ionized hydrogen (H) region.…
Science Prospects for the Southern Wide-field Gamma-ray Observatory: SWGO
SWGO Collaboration, P. Abreu, R. Alfaro +303
Ground-based gamma-ray astronomy is now well established as a key observational approach to address critical topics at the frontiers of astroparticle physics and high-energy astrop…
Discovery of diffuse -ray emission in the vicinity of G213.0-0.6: Supernova remnant versus massive star-forming region
Yuan Li, Gwenael Giacinti, Siming Liu
We report the discovery of high-energy -ray emission in the vicinity of G213.0-0.6, which is debated as a supernova remnant (SNR) or an ionized hydrogen (H) region.…
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…
