Classifying the generation and formation channels of individual LIGO-Virgo-KAGRA observations from dynamically formed binaries
Andrea Antonelli, Konstantinos Kritos, Ken K. Y. Ng +2
We address two important questions in gravitational-wave astronomy. What is the astrophysical formation scenario leading to black-hole binary mergers? Did some of the merging black…
Accurate waveform models for gravitational-wave astrophysics: synergetic approaches from analytical relativity
Andrea Antonelli
Gravitational-wave (GW) astrophysics is a field in full blossom. Since the landmark detection of GWs from a binary black hole on September 14th 2015, several compact-object binarie…
The impact of confusion noise on golden binary neutron-star events in next-generation terrestrial observatories
Luca Reali, Andrea Antonelli, Roberto Cotesta +4
Next-generation terrestrial gravitational-wave observatories will detect signals from compact binary coalescences every year. These signals can last for sever…
Constraining the evolution of Newton's constant with slow inspirals observed from spaceborne gravitational-wave detectors
R. Barbieri, S. Savastano, L. Speri +5
Spaceborne gravitational-wave (GW) detectors observing at milli-Hz and deci-Hz frequencies are expected to detect large numbers of quasi-monochromatic signals. The first and second…
Probing Accretion Physics with Gravitational Waves
Lorenzo Speri, Andrea Antonelli, Laura Sberna +4
Gravitational-wave observations of extreme mass ratio inspirals (EMRIs) offer the opportunity to probe the environments of active galactic nuclei (AGN) through the torques that acc…
A Fisher matrix for gravitational-wave population inference
Jonathan R. Gair, Andrea Antonelli, Riccardo Barbieri
We derive a Fisher matrix for the parameters characterising a population of gravitational-wave events. This provides a guide to the precision with which population parameters can b…
The impact of relativistic corrections on the detectability of dark-matter spikes with gravitational waves
Nicholas Speeney, Andrea Antonelli, Vishal Baibhav +1
Black holes located within a dark matter cloud can create overdensity regions known as dark matter spikes. The presence of spikes modifies the gravitational-wave signals from binar…
Noisy neighbours: inference biases from overlapping gravitational-wave signals
Andrea Antonelli, Ollie Burke, Jonathan R. Gair
Understanding and dealing with inference biases in gravitational-wave (GW) parameter estimation when a plethora of signals are present in the data is one of the key challenges for…
Gravitational spin-orbit and aligned spin-spin couplings through third-subleading post-Newtonian orders
Andrea Antonelli, Chris Kavanagh, Mohammed Khalil +2
The study of scattering encounters continues to provide new insights into the general relativistic two-body problem. The local-in-time conservative dynamics of an aligned-spin bina…
Gravitational spin-orbit coupling through third-subleading post-Newtonian order: from first-order self-force to arbitrary mass ratios
Andrea Antonelli, Chris Kavanagh, Mohammed Khalil +2
Exploiting simple yet remarkable properties of relativistic gravitational scattering, we use first-order self-force (linear-in-mass-ratio) results to obtain arbitrary-mass-ratio re…
Quasi-circular inspirals and plunges from non-spinning effective-one-body Hamiltonians with gravitational self-force information
Andrea Antonelli, Maarten van de Meent, Alessandra Buonanno +2
The self-force program aims at accurately modeling relativistic two-body systems with a small mass ratio (SMR). In the context of the effective-one-body (EOB) framework, current re…
Energetics of two-body Hamiltonians in post-Minkowskian gravity
Andrea Antonelli, Alessandra Buonanno, Jan Steinhoff +2
Advanced methods for computing perturbative, quantum-gravitational scattering amplitudes show great promise for improving our knowledge of classical gravitational dynamics. This is…
