Hard X-ray view of two -ray detected low-luminosity active galactic nuclei: NGC 315 and NGC 4261
Yuwei Yu, Jin Zhang
Aims. The accretion disk of low-luminosity active galactic nuclei (LLAGNs) is a radiatively inefficient accretion flow (RIAF). Our goal is to find evidence of RIAF radiation from L…

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-…
