An Eclipsing Black Widow Pulsar in NGC 6712
Zhen Yan, Zhi-chen Pan, Scott M. Ransom +9
We report the discovery of the first radio pulsar associated with NGC 6712, an eclipsing black widow (BW) pulsar, J18530842A, found by high-sensitivity searches using the Five-h…
A magnetic accretion disk-outflow model for state transition in X-ray binaries
Xinwu Cao, Bei You, Zhen Yan
The hard to soft state transition of the outbursts in X-ray binaries (XRBs) is triggered by the rising of the mass accretion rate due to the disk instability. In order to explain t…
FAST Globular Cluster Pulsar Survey: Twenty-Four Pulsars Discovered in Fifteen Globular Clusters
Zhichen Pan, Lei Qian, Xiaoyun Ma +8
We present the discovery of 24 pulsars in 15 Globular Clusters (GCs) using the Five-hundred-meter Aperture Spherical radio Telescope (FAST). These include the first pulsar discover…
Long-term and multi-wavelength evolution of a changing-look AGN Mrk 1018
Bing Lyu, Zhen Yan, Wenfei Yu +1
The physical mechanism for triggering the changing-look phenomenon in active galactic nuclei (AGNs) is still unclear. We explore this issue based on the multi-wavelength spectral a…
Simultaneous 2.25/8.60 GHz observations of the newly discovered magnetar -- Swift J1818.0-1607
Zhi-Peng Huang, Zhen Yan, Zhi-Qiang Shen +7
Swift J1818.0-1607 discovered in early 2020 is not only the fifth magnetar known with periodic radio pulsations but also the fastest rotating one. Simultaneous 2.25 and 8.60 GHz ob…
Detection of a low frequency quasi-periodic oscillation in the soft state of Cygnus X-1 with Insight-HXMT
Zhen Yan, Stefano Rapisarda, Wenfei Yu
We report the detection of a short-lived narrow quasi-periodic oscillation (QPO) at ~88 mHz in an Insight-HXMT observation during the soft state of the persistent black hole high m…
