"General Relativity and Quantum Cosmology"

Notes on Gravitational Physics

These notes are self-contained, with the first six chapters used for a one-semester course with recommended texts by Wald, Misner, Thorne, and Wheeler (MTW), and, particularly for gravitational waves, by Schutz and by Thorne and Blandford. In its …

Lectures on Gravitational Wave Signatures of Primordial Black Holes

We provide a pedagogical approach to gravitational waves in cosmology with focus on gravitational wave signals related to primordial black holes. These lectures notes contain more details than one is able to present in the two two-hour lectures they …

A Survey of Gravitational Waves

We review the state of the field of gravitational wave astrophysics, framing the challenges, current observations, and future prospects within the context of the predictions of Einstein's theory of general relativity.

Observational Evidence for Primordial Black Holes: A Positivist Perspective

We review numerous arguments for primordial black holes (PBHs) based on observational evidence from a variety of lensing, dynamical, accretion and gravitational-wave effects. This represents a shift from the usual emphasis on PBH constraints and …

Searches for Continuous Gravitational Waves from Neutron Stars: A Twenty-Year Retrospective

Seven years after the first direct detection of gravitational waves, from the collision of two black holes, the field of gravitational wave astronomy is firmly established. A first detection of continuous gravitational waves from rapidly-spinning …

Dark Stars and Gravitational Waves: Topical Review

Motivated by recent observations of compact binary gravitational wave events reported by LIGO/Virgo/KAGRA, we review the basics of dark and hybrid stars and examine their probabilities as mimickers for black holes and neutron stars. This review aims …

The Physics of Gravitational Waves

These lecture notes collect the material that I have been using over the years for various short courses on the physics of gravitational waves, first at the Institut d'Astrophysique de Paris (France), and then at SISSA (Italy) and various …

Gravitational Waves from the Early Universe

These lecture notes are based on the course \"Gravitational waves from the early universe\" given at the 27th W.E. Heraeus \"Saalburg\" Summer School 2021 by Valerie Domcke. Ongoing and future collaborations will probe different frequency ranges of …

Gravitational Wave Astronomy: Astrophysical and Cosmological Inferences

We briefly discuss the most prominent results and specific sources detected by gravitational-wave observatories LIGO-Virgo during first three O1-O3 runs, as well as possible astrophysical and cosmological channels of their formation. We show that it …

Primordial Black Holes

We review aspect of primordial black holes, i.e., black holes which have been formed in the early Universe. Special emphasis is put on their formation, their rôle as dark matter candidates and their manifold signatures, particularly through …
