QPEs from Warped Disk Collisions with EMRIs: Brightness-Recurrence Diagram and Gravitational-Wave Follow-up
Bo-An Chen, Bei You, Giovanni Miniutti +11
Quasi-Periodic Eruptions (QPEs) display correlated long/short and strong/weak patterns that remain unexplained by existing flat-disk collision models. We propose that these feature…
X-ray Quasi-Periodic Oscillations in Active Galactic Nuclei and Their Implications for the Changing Look Phenomenon
Mouyuan Sun, Shuying Zhou, Jihong Liu +12
X-ray timing of active galactic nuclei (AGN) provides a unique probe of gas accretion onto supermassive black holes (SMBHs). Quasi-periodic oscillations (QPOs), which trace gas dyn…
Science Opportunities of Wet Extreme Mass-Ratio Inspirals
Zhenwei Lyu, Zhen Pan, Junjie Mao +2
Wet extreme mass-ratio inspirals (wet EMRIs), which arise from stellar-mass black holes inspiral into supermassive black holes (SMBHs) within the gas-rich environments of Active Ga…
Dynamical Measurement of Supermassive Black Hole Masses: QPE Timing Method
Cong Zhou, Zhen Pan, Ning Jiang +1
Quasi-periodic eruptions (QPEs) are intense repeating soft X-ray bursts with recurrence times about a few hours to a few weeks from galactic nuclei. More and more analyses show tha…
Embers of Active Galactic Nuclei: Tidal Disruption Events and Quasiperiodic Eruptions
Ning Jiang, Zhen Pan
Recent observations have confirmed the direct association between tidal disruption events (TDEs) and quasiperiodic eruptions (QPEs). In addition, TDE hosts and QPE hosts are statis…
