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 in the 0.1 mHz to 1 Hz frequency band which will enable the study of

Three-body encounters in black hole discs around a supermassive black hole: The disc velocity dispersion and the Keplerian tidal field determine the eccentricity and spin-orbit alignment of gravitational wave mergers

Autor: Trani, Alessandro Alberto, Quaini, Stefano, Colpi, Monica

Dynamical encounters of stellar-mass black holes (BHs) in a disc of compact objects around a supermassive BH (SMBH) can accelerate the formation and coalescence of BH binaries. It has been proposed that binary-single encounters among BHs in such disc

Identifying heavy stellar black holes at cosmological distances with next generation gravitational-wave observatories

Autor: Fairhurst, Stephen, Mills, Cameron, Colpi, Monica, Schneider, Raffaella, Sesana, Alberto, Trinca, Alessandro, Valiante, Rosa

We investigate the detectability of single-event coalescing black hole binaries with total mass of $100-600 M_{\odot}$ at cosmological distances ($5 \lesssim z \lesssim 20$) with the next generation of terrestrial gravitational wave observatories, sp

GRMHD simulations of accretion flows onto unequal-mass, precessing massive binary black hole mergers

Autor: Cattorini, Federico, Giacomazzo, Bruno, Colpi, Monica, Haardt, Francesco

In this work, we use general relativistic magnetohydrodynamics simulations to explore the effect of spin orientation on the dynamics of gas in the vicinity of merging black holes. We present a suite of eight simulations of unequal-mass, spinning blac

Massive Black Hole Binaries as LISA Precursors in the Roman High Latitude Time Domain Survey

Andrew, Charisi, Maria, Colpi, Monica, Davelaar, Jordy, De Rosa, Alessandra, D'Orazio, Daniel J., Futrowsky, Kate, Gandhi, Poshak, Graham, Alister W., Greene, Jenny E., Habouzit, Melanie, Haggard, Daryl, Holley-Bockelmann, Kelly, Liu, Xin, Mangiagli, Alberto, Mastrobuono-Battisti, Alessandra, McGee, Sean, Mingarelli, Chiara M.

With its capacity to observe $\sim 10^{5-6}$ faint active galactic nuclei (AGN) out to redshift $z\approx 6$, Roman is poised to reveal a population of $10^{4-6}\, {\rm M_\odot}$ black holes during an epoch of vigorous galaxy assembly. By measuring t
