Secular Evolution of Quasiperiodic Eruptions: eRO-QPE2
Zirui Zhang, Cong Zhou, Zhen Pan
Quasi-periodic eruptions (QPEs) are recurrent soft X-ray flares from galactic nuclei. In this work, we analyze both the quiescent and eruption emission of eRO-QPE2, using 11 XMM-Ne…

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…
