Accretion models for LLAGNs: Model Parameter Estimation and Prediction of their Detectibility
Bidisha Bandyopadhyay, Dominik R. G. Schleicher, Neil Nagar +2
The Event Horizon Telescope (EHT) provides a unique opportunity to probe the physics of supermassive black holes through Very Large Baseline Interferometry (VLBI), such as the exis…
The Bending Feature of the Fermi Bubbles: A Presumed Horizontal Galactic Wind and Its Implication on the Bubbles' Age
Guobin Mou, Dongze Sun, Fuguo Xie
There are two spectacular structures in our Milky Way: the {\it Fermi} bubbles in gamma-ray observations and the North Polar Spur (NPS) structure in X-ray observations. Because of…
NuSTAR Hard X-ray View of Low-luminosity Active Galactic Nuclei: High-energy Cutoff and Truncated Thin Disk
George Younes, Andrew Ptak, Luis C. Ho +5
We report the analysis of simultaneous XMM-Newton+NuSTAR observations of two low-luminosity Active Galactic Nuclei (LLAGN), NGC 3998 and NGC 4579. We do not detect any significant…
Circumbinary discs around merging stellar-mass black holes
Rebecca G. Martin, Chris Nixon, Fu-Guo Xie +1
A circumbinary disc around a pair of merging stellar-mass black holes may be shocked and heated during the recoil of the merged hole, causing a near-simultaneous electromagnetic co…
Insight-HXMT observations of the New Black Hole Candidate MAXI J1535-571: timing analysis
Y. Huang, J. L. Qu, S. N. Zhang +118
We present the X-ray timing results of the new black hole candidate (BHC) MAXI J1535-571 during its 2017 outburst from Hard X-ray Modulation Telescope (\emph{Insight}-HXMT) observa…
A decades-long fast-rise-exponential-decay flare in low-luminosity AGN NGC 7213
Zhen Yan, Fu-Guo Xie
We analysed the four-decades-long X-ray light curve of the low-luminosity active galactic nucleus (LLAGN) NGC 7213 and discovered a fast-rise-exponential-decay (FRED) pattern, i.e.…
