A Note on QPE Timing: False Alarms in O-C
Cong Zhou, Zirui Zhang, Zhen Pan +1
O-C timing analysis is a useful diagnostic tool for quasi-periodic eruptions (QPEs), but their interpretation depends sensitively on the integer cycle number assigned to each erupt…
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…
A Formation Crisis of Repeating Partial Tidal Disruption Events
Zhen Pan, Dong Lai
A number of candidate repeating partial tidal disruption events (rpTDEs) have been reported in recent years. If these events are confirmed, the high fraction of observed rpTDEs amo…
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…
Probing the Strong Gravity Region of Black Holes with eXTP
Qingcui Bu, Cosimo Bambi, Lijun Gou +42
We present the novel capabilities of the enhanced X-ray Timing and Polarimetry (eXTP) mission to study the strong gravity region around stellar-mass black holes in X-ray binary sys…
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…
