From S2 to LISA: Astrometric Bounds on Extreme-Mass-Ratio Inspirals and Bursts
Andrea Caputo, Valerie Domcke
Stellar orbits around the massive black hole at the center of our galaxy provide a unique local probe of the compact-object population in the Galactic Centre and, consequently, of…
Is S301 the Captured Companion of the Hypervelocity Star S5-HVS1?
Andrea Caputo, Giovanni Maria Tomaselli
Stellar binary disruptions through the Hills mechanism produce two fossils: a hypervelocity star (HVS), and a star tightly bound to the supermassive black hole. Among known galacti…
Evolution of Binaries Under Stochastic Perturbations
Andrea Caputo, Giovanni Maria Tomaselli, Chris Hamilton
We develop a general Fokker-Planck framework describing the dynamical evolution of Keplerian binaries subjected to stochastic perturbations. The formalism provides an algorithmic w…
Probing dense environments around Sgr A* with S-stars dynamics
Giovanni Maria Tomaselli, Andrea Caputo
The orbits of stars around Sgr A*, the Milky Way's supermassive black hole, provide a unique laboratory for testing its environment with unprecedented precision. In this work, we c…
