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…
The Advanced X-ray Imaging Satellite (AXIS) Community Science Book
Michael Koss, Nafisa Aftab, Steven W. Allen +395
The AXIS Community Science Book represents the collective effort of 592 scientists worldwide to define the transformative science enabled by the Advanced X-ray Imaging Satellite (A…
Eccentricity distribution of extreme mass ratio inspirals
Davide Mancieri, Luca Broggi, Morgan Vinciguerra +2
We present realistic eccentricity distributions for extreme mass ratio inspirals (EMRIs) forming via the two-body relaxation channel in nuclear star clusters, tracking their evolut…
Prospects for EMRI/MBH parameter estimation using Quasi-Periodic Eruption timings: short-timescale analysis
Joheen Chakraborty, Lisa V. Drummond, Matteo Bonetti +11
Quasi-Periodic Eruptions (QPEs) are luminous, recurring X-ray outbursts from galactic nuclei, with timescales of hours to days. While their origin remains uncertain, leading models…
Can a time evolving, asymmetric broad line region mimic a massive black hole binary?
Erika Sottocorno, Mary Ogborn, Lorenzo Bertassi +3
Gas within the influence sphere of accreting massive black holes is responsible for the emission of the broad lines observed in optical-UV spectra of unobscured active galactic nuc…
The fate of EMRI-IMRI pairs in AGN accretion disks: hydrodynamic and three body simulations
Peng Peng, Alessia Franchini, Matteo Bonetti +2
Extreme-mass-ratio inspirals (EMRIs) and intermediate-mass-ratio inspirals (IMRIs) are important gravitational wave (GW) sources for the Laser Interferometer Space Antenna (LISA).…
Eppur si muove: Evidence of disc precession or a sub-milliparsec SMBH binary in the QPE-emitting galaxy GSN 069
Giovanni Miniutti, Alessia Franchini, Matteo Bonetti +8
X-ray quasi-periodic eruptions (QPEs) are intense soft X-ray bursts from the nuclei of nearby low-mass galaxies typically lasting about one hour and repeating every few. Their phys…
Gas-induced perturbations on the gravitational wave in-spiral of live post-Newtonian LISA massive black hole binaries
Mudit Garg, Alessia Franchini, Alessandro Lupi +2
We investigate the effect of dynamically coupling gas torques with gravitational wave (GW) emission during the orbital evolution of an equal-mass massive black hole binary (MBHB).…
Fragments of harmony amid apparent chaos: a closer look at the X-ray quasi-periodic eruptions of the galaxy RX J1301.9+2747
Margherita Giustini, Giovanni Miniutti, Riccardo Arcodia +17
Quasi-periodic eruptions (QPEs) are an extreme X-ray variability phenomenon associated with low-mass supermassive black holes. First discovered in the nucleus of the galaxy GSN 069…
