No evidence for a supermassive black hole binary in GSN 069
Yuhe Zeng, Zhen Pan, Bin Liu +1
Quasi-periodic eruptions (QPEs) are recurrent soft X-ray flares from galactic nuclei and provide a new time-domain probe of stellar-mass objects (SMOs) orbiting supermassive black…
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…
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…
Secular evolution of quasi-periodic eruptions
Cong Zhou, Yuhe Zeng, Zhen Pan
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…
