Much of the success of gravitational-wave astronomy rests on perturbation theory.
Historically, perturbative analysis of gravitational-wave sources has largely focused on post …

A numerical-relativity calculation yields in general a solution of the Einstein equations
including also a radiative part, which is in practice computed in a region of finite extent …

Accurate models of gravitational waves from merging black holes are necessary for
detectors to observe as many events as possible while extracting the maximum science …

We improve the accuracy of the effective-one-body (EOB) waveforms that were employed
during the first observing run of Advanced LIGO for binaries of spinning, nonprecessing …

In this paper we discuss the anatomy of frequency-domain gravitational-wave signals from
nonprecessing black-hole coalescences with the goal of constructing accurate …

The origin of black hole mergers discovered by the LIGO and Virgo gravitational-wave
observatories is currently unknown. GW190521, is the heaviest black hole merger detected …

We compare the science capabilities of different eLISA mission designs, including four-link
(two-arm) and six-link (three-arm) configurations with different arm lengths, low-frequency …

Advanced LIGO-Virgo have reported a short gravitational-wave signal (GW190521)
interpreted as a quasicircular merger of black holes, one at least populating the pair …

Numerical-relativity simulations for the merger of binary neutron stars are performed for a
variety of equations of state (EOSs) and for a plausible range of the neutron-star mass …

We present new (3+ 1) D numerical relativity simulations of the binary neutron star (BNS)
merger and postmerger phase. We focus on a previously inaccessible region of the binary …
