The open-access journal Living Reviews in Relativity has published two new review articles in July/August 2023:

Auclair, P., Bacon, D., Baker, T. et al. [The LISA Cosmology WG]
Cosmology with the Laser Interferometer Space Antenna.
Living Rev Relativ 26, 5 (2023).

Abstract: The Laser Interferometer Space Antenna (LISA) has two scientific objectives of cosmological focus: to probe the expansion rate of the universe, and to understand stochastic gravitational-wave backgrounds and their implications for early universe and particle physics, from the MeV to the Planck scale. However, the range of potential cosmological applications of gravitational-wave observations extends well beyond these two objectives. This publication presents a summary of the state of the art in LISA cosmology, theory and methods, and identifies new opportunities to use gravitational-wave observations by LISA to probe the universe.

Note: This article is part of a joint Topical Collection between Living Reviews and the journal General Relativity and Gravitation (

Solvable models of quantum black holes: a review on Jackiw-Teitelboim gravity.
Living Rev Relativ 26, 4 (2023).

Abstract: We review recent developments in Jackiw-Teitelboim gravity. This is a simple solvable model of quantum gravity in two dimensions (that arises e.g. from the s-wave sector of higher dimensional gravity systems with spherical symmetry). Due to its solvability, it has proven to be a fruitful toy model to analyze important questions such as the relation between black holes and chaos, the role of wormholes in black hole physics and holography, and the way in which information that falls into a black hole can be recovered.
