The X-ray Variability of the Ultraluminous X-ray Sources in the NGC 4631 galaxy
Jiashun Chen, Jianfeng Wu, Zikun Lin
We perform a systematic study on the long-term X-ray variability for the five ultraluminous X-ray sources (ULXs) in the NGC 4631 galaxy (X1-X5), using Chandra, XMM-Newton, and Swif…
Early results from the SVOM Observatory Science program
A. Coleiro, L. Tao, F. Cangemi +44
We present the organisation and early results from the Observatory Science program of the Space-based multi-band astronomical Variable Objects Monitor (SVOM), based on data collect…
Jet-ISM Interaction and Multi-channel AGN Feedback in the Post-merger Galaxy 4C+29.30
Xiao Cao, Junfeng Wang, Yan-Mei Chen +5
4C+29.30 is a post-merger galaxy hosting a rejuvenated active galactic nucleus (AGN) with a complex multi-scale radio morphology, making it an ideal laboratory to study the interpl…
Questing a Coherent Definition of Weak-line Quasars and its Physical Implications
Xiaoqiang Cheng, Jianfeng Wu, Qiaoya Wu
Weak-line quasars (WLQs) are a subset of type 1 quasars with remarkably weak high-ionization broad emission lines but normal optical/UV continua. Using 371,091 quasars from SDSS DR…
Central Massive Black Holes Are Not Ubiquitous in Local Low-Mass Galaxies
Fan Zou, Elena Gallo, Anil C. Seth +13
The black-hole occupation fraction () defines the fraction of galaxies that harbor central massive black holes (MBHs), irrespective of their accretion activity leve…
The X-ray enhancements of radio-loud quasars at high redshift: New results at
Zihao Zuo, Shifu Zhu, W. N. Brandt +4
Highly radio-loud quasars (HRLQs; ) at show apparent enhanced X-ray emission compared to matched HRLQs at lower redshifts, perhaps due to a redshift-depend…
The weakness of soft X-ray intensity: possible physical reason for weak line quasars
Jiancheng Wu, Qingwen Wu, Chichuan Jin +8
Weak-line quasars (WLQs) are a notable group of active galactic nuclei (AGNs) that show unusually weak UV lines even though their optical-UV continuum shapes are similar to those o…
The X-ray Emission Reveals the Coronal Activities of Semi-detached Binaries
Junhui Liu, Jianfeng Wu
X-ray emission is an important tracer of stellar magnetic activity. We carried out a systematic correlation analysis for the X-ray luminosity , bolometric luminosit…
HI Absorption in Low-power Radio AGNs Detected by FAST
Qingzheng Yu, Taotao Fang, Junfeng Wang +1
We report the discovery of three HI absorbers toward low-power radio active galactic nuclei (AGNs) in a pilot HI absorption survey with the Five-hundred-meter Aperture Spherical ra…
