Searching for -ray emission from a bona fide Compact Symmetric Object sample: a -ray signal near GB6 J0906+4124
Ying-Ying Gan, Kai Wang, Ji-Shun Lian +1
As a particular subclass of active galactic nuclei (AGNs), compact symmetric objects (CSOs) have attracted significant attention due to potential role as young AGNs. Several -ra…
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…
Lobe-dominated gamma-ray Emission of Compact Symmetric Objects
Ying-Ying Gan, Hai-Ming Zhang, Xing Yang +2
The -ray emitting compact symmetric objects (CSOs) PKS 1718--649, NGC 3894, and TXS 0128+554 are lobe-dominated in the radio emission. In order to investigate their -ray radi…
X-ray and GeV-gamma-ray emission property of TeV Compact Symmetric Object PKS 1413+135 and Implication for Episodic Jet Activity
Ying-Ying Gan, Jin Zhang, Su Yao +3
PKS 1413+135, a compact symmetric object (CSO) with a two-side pc-scale structure in its miniature radio morphology, is spatially associated with 4FGL J1416.1+1320 and recently det…
GeV -ray Emission of Compact Steep-Spectrum Source 4C +39.23B
Ying Gu, Hai-Ming Zhang, Ying-Ying Gan +3
Thirteen yr observation data of 4FGL J0824.9+3915 with the Large Area Telescope on board the Fermi Gamma Ray Space Telescope (Fermi/LAT) are analyzed for revisiting whether 4C +39.…
Highly Variable -Ray Emission of CTD 135 and Implications for its Compact Symmetric Structure
Ying-Ying Gan, Hai-Ming Zhang, Jin Zhang +4
The -ray emission properties of CTD 135, a typical compact symmetric object (CSO), are investigated with 11-year Fermi/LAT observations. We show that it has bright and sig…
Jet Properties of Compact Steep-Spectrum Sources and an Eddington-Ratio-Driven Unification Scheme of Jet Radiation in Active Galactic Nuclei
Jin Zhang, Hai-Ming Zhang, Ying-Ying Gan +3
Compact steep-spectrum sources (CSSs) likely represent a population of young radio-loud active galactic nuclei (AGNs) and have been identified as gamma-ray emitting sources. We pre…
Spectral Lag for a Radiating Jet Shell with a High Energy Cut-off Radiation Spectrum
Shen-Shi Du, Da-Bin Lin, Rui-Jing Lu +5
Recent research shows that the spectral lag is closely related to the spectral evolution in GRBs. In this paper, we study the spectral lag for a radiating jet shell with a high-ene…
