Multimessenger prospects of quasi-periodic eruptions
VojtÄch 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…
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…
The LISA Astrophysics "Disc-IMRI" Code Comparison Project: Intermediate-Mass-Ratio Binaries in AGN-Like Discs
Andrea Derdzinski, Alexander J. Dittmann, Alessia Franchini +16
Upcoming space-based gravitational wave detectors such as LISA, the Laser Interferometer Space Antenna, will be sensitive to extreme- and intermediate-mass-ratio inspirals (EMRIs a…
Tidal disruption events with SPH-EXA: resolving the return of the stream
Noah Kubli, Alessia Franchini, Eric R. Coughlin +4
In a tidal disruption event (TDE), a star is disrupted by the tidal field of a massive black hole, creating a debris stream that returns to the black hole, forms an accretion flow,…
Suppressed "lump" EM signature in radiation pressure dominated accreting massive black hole binaries
Fabiola Cocchiararo, Alessia Franchini, Alessandro Lupi +1
We investigate the impact of radiation pressure on electromagnetic signatures of accreting massive black hole binaries (MBHBs) at milli-parsec separations, using 3D hyper-Lagrangia…
Identifying massive black hole binaries via light curve variability in optical time-domain surveys
Alfredo Chiesa, David Izquierdo-Villalba, Alberto Sesana +5
Accreting massive black hole binaries (MBHBs) often display periodic variations in their emitted radiation, providing a distinctive signature for their identification. In this work…
