Test for LISA foreground Gaussianity and stationarity: extreme mass-ratio inspirals
Manuel Piarulli, Riccardo Buscicchio, Federico Pozzoli +3
Extreme Mass Ratio Inspirals (EMRIs) are key observational targets for the Laser Interferometer Space Antenna (LISA) mission. Unresolvable EMRI signals contribute to the formation…
Hanging on the cliff: Extreme mass ratio inspiral formation with local two-body relaxation and post-Newtonian dynamics
Davide Mancieri, Luca Broggi, Matteo Bonetti +1
Extreme mass ratio inspirals (EMRIs) are anticipated to be primary gravitational wave sources for LISA (Laser Interferometer Space Antenna). They form in dense nuclear clusters whe…
Resolving the nano-Hz gravitational wave sky: the detectability of eccentric binaries with PTA experiments
Riccardo J. Truant, David Izquierdo-Villalba, Alberto Sesana +2
Pulsar Timing Array (PTA) collaborations reported evidence of a nano-Hz stochastic gravitational wave background (sGWB) compatible with an adiabatically inspiraling population of m…
An effective model for the tidal disruption of satellites undergoing minor mergers with axisymmetric primaries
Ludovica Varisco, Massimo Dotti, Matteo Bonetti +2
According to the hierarchical formation paradigm, galaxies form through mergers of smaller entities and massive black holes (MBHs), if lurking at their centers, migrate to the nucl…
Repeating partial disruptions and two-body relaxation
Luca Broggi, Nicholas C. Stone, Taeho Ryu +4
Two-body relaxation may drive stars onto near-radial orbits around a massive black hole, resulting in a tidal disruption event (TDE). In some circumstances, stars are unlikely to u…
Testing EMRI models for Quasi-Periodic Eruptions with 3.5 years of monitoring eRO-QPE1
Joheen Chakraborty, Riccardo Arcodia, Erin Kara +13
Quasi-Periodic Eruptions (QPEs) are luminous X-ray outbursts recurring on hour timescales, observed from the nuclei of a growing handful of nearby low-mass galaxies. Their physical…
LISA Definition Study Report
Monica Colpi, Karsten Danzmann, Martin Hewitson +108
The Laser Interferometer Space Antenna (LISA) is the first scientific endeavour to detect and study gravitational waves from space. LISA will survey the sky for Gravitational Waves…
Connecting low-redshift LISA massive black hole mergers to the nHz stochastic gravitational wave background
David Izquierdo-Villalba, Alberto Sesana, Monica Colpi +4
Pulsar Timing Array (PTA) experiments worldwide recently reported evidence of a nHz stochastic gravitational wave background (sGWB) compatible with the existence of slowly inspiral…
Emission signatures from sub-pc Post-Newtonian binaries embedded in circumbinary discs
Alessia Franchini, Matteo Bonetti, Alessandro Lupi +1
We study the dynamical evolution of quasi-circular equal mass massive black hole binaries embedded in circumbinary discs from separations of down to the merger,…
