The focus of this Chapter is on describing the prospective sources of the gravitational wave universe accessible to present and future observations, from kHz, to mHz down to nano-Hz frequencies. The multi-frequency gravitational wave universe gives a deep view into the cosmos, inaccessible otherwise. It has as main actors core-collapsing massive stars, neutron stars, coalescing compact object binaries of different flavours and stellar origin, coalescing massive black hole binaries, extreme mass… 

Black holes, gravitational waves and fundamental physics: a roadmap

The grand challenges of contemporary fundamental physics—dark matter, dark energy, vacuum energy, inflation and early universe cosmology, singularities and the hierarchy problem—all involve gravity

The n-Hz amplitude of the stochastic gravitational wave background confronting galaxy formation models

We estimate the amplitude of the nano-Hz stochastic gravitational wave background (GWB) resulting from an unresolved population of inspiralling massive black hole binaries (MBHBs). To this aim, we

This review will summarize the current state of research of the stochastic background, from the sources of these gravitational waves to the current methods used to observe them.

Gravitational wave emission from unstable accretion discs in tidal disruption events

Gravitational waves can be emitted by accretion discs if they undergo instabilities that generate a time varying mass quadrupole. In this work we investigate the gravitational signal generated by a

Massive black hole evolution models confronting the n-Hz amplitude of the stochastic gravitational wave background

We estimate the amplitude of the nano-Hz stochastic gravitational wave background (GWB) resulting from an unresolved population of inspiralling massive black hole binaries (MBHBs). To this aim, we

The existence of black holes in the intermediate mass interval between one hundred and ten thousand solar masses, filling the gap between the stellar and the supermassive black holes is a key

Lecture notes on black hole binary astrophysics

We describe some key astrophysical processes driving the formation and evolution of black hole binaries of different nature, from stellar-mass to supermassive systems. In the first part, we focus on

Observable gravitational waves from tidal disruption events and their electromagnetic counterpart

We estimate the rate of tidal disruption events (TDEs) that will be detectable with future gra vitational wa ve detectors as well as the most probable properties of these events and their possible

Hierarchical mergers of stellar-mass black holes and their gravitational-wave signatures

We review theoretical findings, astrophysical modeling, and current gravitational-wave evidence of hierarchical stellar-mass black-hole mergers. While most of the compact binary mergers detected by

Quasinormal modes of slowly-rotating black holes in dynamical Chern-Simons gravity

The detection of gravitational waves from compact binary mergers by the LIGO/Virgo collaboration has, for the first time, allowed us to test relativistic gravity in its strong, dynamical and nonlinear



Low-frequency gravitational-wave science with eLISA/NGO

We review the expected science performance of the New Gravitational-Wave Observatory (NGO, a.k.a. eLISA), a mission under study by the European Space Agency for launch in the early 2020s. eLISA will

Gravitational waves from cosmological phase transitions

First order phase transitions in the early universe can give rise to a stochastic background of gravitational waves. A hypothetical first order electroweak phase transition is particularly

We review the ensemble of anticipated gravitational-wave (GW) emission processes in stellar core collapse and postbounce core-collapse supernova evolution. We discuss recent progress in the modeling

Observing Supermassive Black Holes Across Cosmic Time: From Phenomenology to Physics

In the last decade, a combination of high sensitivity and spatial resolution observations and of coordinated multi-wavelength surveys has revolutionized our view of extra-galactic black hole (BH)

Gravitational Radiation from Post-Newtonian Sources and Inspiralling Compact Binaries

The current state of the art on post-Newtonian methods as applied to the dynamics and gravitational radiation of general matter sources (including the radiation reaction back onto the source) and inspiralling compact binaries is presented.

The first gravitational-wave source from the isolated evolution of two stars in the 40–100 solar mass range

High-precision numerical simulations of the formation of binary black holes via the evolution of isolated binary stars are reported, providing a framework within which to interpret the first gravitational-wave source, GW150914, and to predict the properties of subsequent binary-black-hole gravitational- wave events.

Testing General Relativity with Low-Frequency, Space-Based Gravitational-Wave Detectors

These are the tests of general relativity that will become possible with space-based gravitational-wave detectors operating in the ∼ 10−5 − 1 Hz low-frequency band and the remarkable richness of astrophysics, astronomy, and cosmology in the low- frequencies make the case even stronger.
