Resonant dynamics of extreme mass-ratio inspirals in a perturbed Kerr spacetime
Zhen Pan, Huan Yang, Laura Bernard +1
Extreme mass-ratio inspirals (EMRI) are one of the most sensitive probes of black hole spacetimes with gravitational wave measurements. In this work, we systematically analyze the…

Zhen Pan, Huan Yang
One of the primary targets of third-generation (3G) ground-based gravitational wave (GW) detectors is detecting the stochastic GW background (SGWB) from early universe processes. T…
X-ray view of a merging supermassive black hole binary candidate SDSSJ1430+2303: Results from the first ~200 days of observations
Liming Dou, Ning Jiang, Tinggui Wang +7
Recently we discovered an unprecedented supermassive black hole binary (SMBHB) candidate in the nearby Seyfert galaxy SDSS J1430+2303, which is predicted to merge within three year…
Repeating Fast Radio Bursts from Neutron Star Binaries: Multi-band and Multi-messenger Opportunities
Zhen Pan, Huan Yang, Kent Yagi
Recent observations indicate that magnetars may commonly reside in merging compact binaries and at least part of fast radio bursts (FRBs) are sourced by magnetar activities. It is…
Dynamical Instability of Self-Gravitating Membranes
Huan Yang, Beatrice Bonga, Zhen Pan
We show that a generic relativistic membrane with in-plane pressure and surface density having the same sign is unstable with respect to a series of warping mode instabilities with…
VLBI imaging of the pre-coalescence SMBHB candidate SDSS J143016.05+230344.4

Context. Recently, SDSS J143016.05+230344.4 (J1430+2303) was reported to be a supermassive black hole binary (SMBHB) in the final coalescence phase. It is probably the first SMBHB…
Tick-Tock: The Imminent Merger of a Supermassive Black Hole Binary
Ning Jiang, Huan Yang, Tinggui Wang +9
Supermassive black hole binaries (SMBHs) are a fascinating byproduct of galaxy mergers in the hierarchical universe. In the last stage of their orbital evolution, gravitational wav…
Science Potential for Stellar-mass Black Holes as Neighbors of Sgr A*
Shammi Tahura, Zhen Pan, Huan Yang
It has been suggested that there is possibly a class of stellar-mass black holes (BHs) residing near (distance ) the galactic center massive black hole, Sgr A*. Possibl…
Mass-gap extreme mass ratio inspirals
Zhen Pan, Zhenwei Lyu, Huan Yang
In this work, we propose a new subclass of extreme-mass-ratio-inspirals (EMRIs): mass-gap EMRIs, consisting of a compact object in the lower mass gap and a m…
Supercritical accretion of stellar-mass compact objects in active galactic nuclei
Zhen Pan, Huan Yang
Accretion disks of active galactic nuclei (AGN) have been proposed as promising sites for producing both (stellar-mass) compact object mergers and extreme mass ratio inspirals. Alo…
Wet Extreme Mass Ratio Inspirals May Be More Common For Spaceborne Gravitational Wave Detection
Zhen Pan, Zhenwei Lyu, Huan Yang
Extreme Mass Ratio Inspirals (EMRIs) can be classified as dry EMRIs and wet EMRIs based on their formation mechanisms. Dry (or the "loss-cone") EMRIs, previously considered as the…
Formation Rate of Extreme Mass Ratio Inspirals in Active Galactic Nuclei
Zhen Pan, Huan Yang
Extreme Mass Ratio Inspirals (EMRIs) are important sources for space-borne gravitational wave detectors, such as LISA (Laser Interferometer Space Antenna) and TianQin. Previous EMR…
