X-ray Emission Properties of a Compact Symmetric Object Sample
Ying-Ying Gan, Su Yao, Tan-Zheng Wu +2
We present a comprehensive analysis of the X-ray observations obtained from \xmm\, and \chandra\, for a sample of bona-fide Compact Symmetric Objects (CSOs) to investigate their X-…
Origin of the Very High Energy γ-rays in the Low-luminosity Active Galactic Nucleus NGC 4278
Ji-Shun Lian, Jia-Xuan Li, Xin-Ke Hu +4
NGC 4278, a Low-luminosity active galactic nucleus (AGN), is generally classified as a low-ionization nuclear emission line region (LINER). Recently, it has been reported to be ass…
Study of γ-ray Emission from a Compact Radio Galaxy with the Fermi Large Area Telescope
Tan-Zheng Wu, Yu-Wei Yu, Ying-Ying Gan +2
The radio galaxy PKS 1007+142 is classified as a compact steep-spectrum source (CSS) and belongs to the class of young Active Galactic Nuclei (AGNs). In this paper, we investigate…
Fermi Large Area Telescope Detection of Gamma-Rays from NGC 6251 Radio Lobe
Yu-Wei Yu, Hai-Ming Zhang, Ying-Ying Gan +3
We report on the detection of extended -ray emission from lobes in the radio galaxy NGC 6251 using observation data of Fermi Large Area Telescope (Fermi-LAT). The maximum likeli…
X-Ray Polarization Variability of High Spectral Peak BL Lacertaes: Cases of 1ES 1959+650 and PKS 2155-304
Xin-Ke Hu, Yu-Wei Yu, Jin Zhang +5
The high-energy-peaked BL Lacertae objects (HBLs) are the main targets of the Imaging X-ray Polarimetry Explorer (IXPE) for investigating the mechanisms of radiation and particle a…
