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…

Gravitational Waves from Cosmic Dawn: Tracing Cosmic Black Hole Binaries with ET, LGWA, and LISA

Nazanin Davari, Rosa Valiante, Alessandro Trinca +8

Next-generation detectors, such as LISA, LGWA, and ET, will for the first time probe the high redshift Universe, offering unique insight into the birth, growth, and dynamics of the…

Even a precessing clock is right twice per orbit -- The super-periods of eRO-QPE2 and challenges for quasi-periodic eruption orbital models

R. Arcodia, G. Miniutti, J. Chakraborty +25

We present OC (``observed minus calculated'') timing analysis of the quasi-periodic eruption (QPE) source eRO-QPE2 with a multi-mission X-ray campaign, which includes 32 observe…

Two-body relaxation in the EMRI-TDE disk model for Quasi Periodic Eruptions

Chiara Maria Allievi, Luca Broggi, Alberto Sesana +1

Quasi Periodic Eruptions (QPEs) are luminous bursts of soft X-rays recently discovered in galactic nuclei. They repeat on timescales of hours to weeks, superimposed to an otherwise…

Spacetime in motion: an evolving relativistic binary black hole metric for GIZMO

Giacomo Fedrigo, Alessandro Lupi, Alessia Franchini +1

The last evolutionary stages of massive black hole binaries prior to coalescence is dominated by the emission of gravitational waves, which will be probed by the future Laser Inter…
