An extreme-mass-ratio burst (EMRB) is a gravitational wave signal emitted when a compact object passes through periapsis on a highly eccentric orbit about a much more massive body, in our case a stellar mass object about the 4.31 \times 10^6 M_sol massive black hole (MBH) in the Galactic Centre. We investigate how EMRBs could constrain the parameters of the Galaxy's MBH. EMRBs should be detectable if the periapsis is r_p < 65 r_g for a \mu = 10 M_sol orbiting object, where r_g = GM/c^2 is the… Expand

Gravitational burst radiation from pulsars in the Galactic centre and stellar clusters
Pulsars (PSRs) orbiting intermediate or supermassive black holes at the centre of galaxies and globular clusters are known as Extreme Mass Ratio Binaries (EMRBs) and have been identified as precisionExpand

We discuss the properties of stellar mass black hole (BH) mergers induced by tidal encounters with a massive BH at galactic centres or potentially in dense star clusters. The tidal disruption ofExpand
Gravitational waves from extreme-mass-ratio inspirals in equatorially eccentric orbits
Based on the numerical frame which combines the effective one-body (EOB) dynamics with the frequency-domain Teukolsky equation, we calculate the waveforms from the extreme-mass-ratio inspiralsExpand
Gravitational wave energy emission and detection rates of Primordial Black Hole hyperbolic encounters.

Indirect (source-free) integration method. II. Self-force consistent radial fall
We apply our method of indirect integration, described in Part I, at fourth order, to the radial fall affected by the self-force. The Mode-Sum regularisation is performed in the Regge-Wheeler gaugeExpand
Relativistic astrophysics at GR20
We report the recent advances in Relativistic Astrophysics as presented at the GR20 meeting in Warsaw, Poland, in July 2013.
