Multimessenger prospects of quasi-periodic eruptions
Vojtěch Witzany, Alessia Franchini, Matteo Bonetti +1
Quasi-Periodic Eruptions (QPEs) are recurring soft X-ray transients that may be generated by inspirals of stellar-mass objects spiraling into supermassive black holes, known as ext…
Repeating Nuclear Transients as Candidate Electromagnetic Counterparts of LISA Extreme Mass Ratio Inspirals
Shubham Kejriwal, Vojtech Witzany, Michal Zajacek +2
Extreme-mass-ratio inspirals (EMRIs) are one of the primary targets for the recently adopted millihertz gravitational-wave (GW) observatory LISA. Some previous studies have argued…
A Case for a Binary Black Hole System Revealed via Quasi-Periodic Outflows
Dheeraj R. Pasham, Francesco Tombesi, Petra Sukova +33
Binaries containing a compact object orbiting a supermassive black hole are thought to be precursors of gravitational wave events, but their identification has been extremely chall…
Alive but Barely Kicking: News from 3+ years of Swift and XMM-Newton X-ray Monitoring of Quasi-Periodic Eruptions from eRO-QPE1
Dheeraj R. Pasham, Eric R. Coughlin, Michal Zajacek +11
Quasi-periodic Eruptions (QPEs) represent a novel class of extragalactic X-ray transients that are known to repeat at roughly regular intervals of a few hours to days. Their underl…
X-ray eruptions every 22 days from the nucleus of a nearby galaxy
Muryel Guolo, Dheeraj R. Pasham, Michal Zajaček +15
Galactic nuclei showing recurrent phases of activity and quiescence have recently been discovered, with recurrence times as short as a few hours to a day -- known as quasi-periodic…
Science with a small two-band UV-photometry mission III: Active Galactic Nuclei and nuclear transients
M. Zajaček, B. Czerny, V. K. Jaiswal +14
In this review (the third in the series focused on a small two-band UV-photometry mission), we assess possibilities for a small UV two-band photometry mission in studying accreting…
