Multi-Period Fermi-LAT and LHAASO Constraints on Axion-Like Particles from Mrk 421 via Profile Likelihood with Gaussian Copula Correlation
Longhua Qin, Jiancheng Wang, Chuyuan Yang +9
We present a joint multi-period analysis of axion-like particles (ALPs) using five sets of simultaneous Fermi-LAT and LHAASO observations of the TeV blazar Mrk~421. Photon-ALP osci…
Constraints on Extragalactic Background Light using TeV Observations of BL Lacertae objects
Longhua Qin, Jiancheng Wang, Quangui Gao +5
The extragalactic background light (EBL) in the IR to UV bands partly absorbs very high energy (VHE, 100GeV) ray photons travelling over cosmological distances via pai…
The gamma-ray and Optical Variability Analysis of the BL Lac Object 3FGL J0449.4-4350
Xing Yang, Tingfeng Yi, Yan Zhang +4
We have assembled the historical light curves of the BL Lac Object 3FGL J0449.4-4350 at optical and gamma-ray bands, the time spanning about 10 years, analyzed the periodic variabi…
The Broad Band Spectral Energy Distributions of SDSS Blazars
Huaizhen Li, Luoen Chen, Yunguo Jiang +1
We compiled the radio, optical, and X-ray data of blazars from the Sloan Digital Sky Survey (SDSS) database, and presented the distribution of luminosities and broad band spectral…
