Fermi-LAT Detection of a Gamma-ray Excess toward the Radio-quiet Narrow-line Seyfert 1 Galaxy 1H 1934-063
Yangji Li, Jinming Bai, Xiong Jiang +1
We report a -ray excess toward the radio-quiet narrow-line Seyfert 1 galaxy 1H 1934-063 using data collected by the Large Area Telescope (LAT) on board the Fermi Gamma-ray Space…
The First GeV Gamma-Ray Flares from the CSO-like Source 4C 76.03
Xiong Jiang, Hai Lei, Hao-Yi Huang +3
We report the first detection of GeV gamma-ray flaring activity from the compact symmetric object (CSO)-like source 4C 76.03, based on 17 years of Fermi-LAT observations. Its long-…
First Detection of -Ray Emission from the Compact Symmetric Object JVAS J1311+1658
Xiong Jiang, Yang-Ji Li, Hai Lei +1
We report the first detection of -ray emission from the young radio galaxy JVAS~J1311+1658, classified as a compact symmetric object (CSO). This detection is characterized by a…
The -ray-emitting blazar B3 1239+376 at = 3.82 identified in a multi-wavelength context
Wei Zhang, Neng-Hui Liao, Hao-Yi Huang +6
Among thousands of extragalactic -ray emitters, only a handful of distant ( 3) sources are detected. Yet, they are crucial probes shedding light on the cosmic evolution of…
