Timing and Spectral Studies of PSR J2022+3842 with NICER and NuSTAR
Jia-Ning Hu, Xiang-Hua Li, Xian-Ao Wang +6
We report on the long-term timing analysis of PSR J2022+3842 using observations from the Neutron Star Interior Composition Explorer (NICER), along with spectral properties derived…
Ultrahigh-Energy Gamma-ray Emission Associated with Black Hole-Jet Systems
The LHAASO Collaboration, Zhen Cao, Felix Aharonian +315
Black holes (BH), one of the most intriguing objects in the universe, can manifest themselves through electromagnetic radiation initiated by the accretion flow. Some stellar-mass B…
Implications of a Possible Spectral Structure of Cosmic-ray Protons Unveiled by the DAMPE
Lin Nie, Yang Liu, Zejun Jiang
The recent observations revealed that the cosmic-ray (CR) proton spectrum showed a complex structure: the hardening at and softening at . Howeve…
Flux Variations of Cosmic Ray Air Showers Detected by LHAASO-KM2A During a Thunderstorm on 10 June 2021
LHAASO Collaboration, F. Aharonian, Q. An +268
The Large High Altitude Air Shower Observatory (LHAASO) has three sub-arrays, KM2A, WCDA and WFCTA. The flux variations of cosmic ray air showers were studied by analyzing the KM2A…
Ultrahigh-energy Gamma-Ray Radiation from the Crab Pulsar Wind Nebula
Lin Nie, Yang Liu, Zejun Jiang +1
It has been long debated whether the high-energy gamma-ray radiation from the Crab nebula stems from leptonic or hadronic processes. In this work, we investigate the multi-band non…
Likely GeV emission from an old Supernova Remnant: SNR G206.9+2.3
Yunchuan Xiang, Zejun Jiang
A novel -ray supernova remnant (SNR) G206.9+2.3 is first reported in this study. We arrived at this conclusion after analyzing 12.4 years of observation data of the Fermi Large…
The Likely Counterpart to -Ray Excess from The Northwest Region of Arp 220
Yun-chuan Xiang, Jun-hao Deng, Ze-jun Jiang
The unknown -ray excess in the northwest region of Arp 220 was revisited by analyzing 11.8 years of the \textit{Fermi} Large Area Telescope (\textit{Fermi}-LAT) data in th…
Evaluation of Hadronic Emission in Starburst Galaxies and Star-forming Galaxies
Yun-chuan Xiang, Ze-jun Jiang, Yun-yong Tang
In this work, we reanalyzed 11 years of spectral data from the \textit{Fermi} Large Area Telescope (\textit{Fermi}-LAT) of currently observed starburst galaxies (SBGs) and star-for…
likely Detection of GeV gamma-Ray Emission from the composite supernova remnant COMP G327.1+1.1 with Fermi-LAT
Yunchuan Xiang, Yi Xing, Zejun Jiang
We report the likely GeV -ray emission from the composite supernova remnant (SNR) COMP G327.1+1.1 by analyzing 12.2 years of the \textit{Fermi} Large Area Telescope (\text…
Fermi-LAT Detection of GeV Gamma-Ray Emission from The Highly Asymmetric Shell Supernova Remnant: SNR G317.3-0.2
Yunchuan Xiang, Zejun Jiang, Yunyong Tang
In this paper, we report the first extended GeV -ray emission, at a significant level of 8.13, from the region of the supernova remnant (SNR) SNR G317.3-0.2 by analyzi…
