Beyond-eikonal diffraction integral in gravitational lensing
Emma Bruyère, Giulia Cusin, Cyril Pitrou
We revisit the derivation of the diffraction integral, which is an approximate evaluation of the Kirchhoff integral, widely used in the literature for phenomenological applications…
The Science of the Einstein Telescope
Adrian Abac, Raul Abramo, Simone Albanesi +485
Einstein Telescope (ET) is the European project for a gravitational-wave (GW) observatory of third-generation. In this paper we present a comprehensive discussion of its science ob…
Measurement of the Cross-Correlation Angular Power Spectrum Between the Stochastic Gravitational Wave Background and Galaxy Over-Density
Kate Z. Yang, Jishnu Suresh, Giulia Cusin +5
We study the cross-correlation between the stochastic gravitational-wave background (SGWB) generated by binary black hole (BBH) mergers across the universe and the distribution of…
Science with the Einstein Telescope: a comparison of different designs
Marica Branchesi, Michele Maggiore, David Alonso +73
The Einstein Telescope (ET), the European project for a third-generation gravitational-wave detector, has a reference configuration based on a triangular shape consisting of three…
Aberration of gravitational waveforms by peculiar velocity
Camille Bonvin, Giulia Cusin, Cyril Pitrou +3
One key prediction of General Relativity is that gravitational waves are emitted with a pure spin-2 polarisation. Any extra polarisation mode, spin-1 or spin-0, is consequently con…
New Horizons for Fundamental Physics with LISA
K. G. Arun, Enis Belgacem, Robert Benkel +138
The Laser Interferometer Space Antenna (LISA) has the potential to reveal wonders about the fundamental theory of nature at play in the extreme gravity regime, where the gravitatio…
Observing GW190521-like binary black holes and their environment with LISA
Laura Sberna, Stanislav Babak, Sylvain Marsat +8
Binaries of relatively massive black holes like GW190521 have been proposed to form in dense gas environments, such as the disks of Active Galactic Nuclei (AGNs), and they might be…
Detection of Early-Universe Gravitational Wave Signatures and Fundamental Physics
Robert Caldwell, Yanou Cui, Huai-Ke Guo +34
Detection of a gravitational-wave signal of non-astrophysical origin would be a landmark discovery, potentially providing a significant clue to some of our most basic, big-picture…
The Next Generation Global Gravitational Wave Observatory: The Science Book
Vicky Kalogera, B. S. Sathyaprakash, Matthew Bailes +88
The next generation of ground-based gravitational-wave detectors will observe coalescences of black holes and neutron stars throughout the cosmos, thousands of them with exceptiona…
Polarization distortions of lensed gravitational waves
Charles Dalang, Giulia Cusin, Macarena Lagos
In general relativity (GR), gravitational waves (GWs) propagate the well-known plus and cross polarization modes which are the signature of a massless spin-2 field. However, diffra…
Prospects for Fundamental Physics with LISA
Enrico Barausse, Emanuele Berti, Thomas Hertog +318
In this paper, which is of programmatic rather than quantitative nature, we aim to further delineate and sharpen the future potential of the LISA mission in the area of fundamental…
Gravitational wave propagation beyond geometric optics
Giulia Cusin, Macarena Lagos
It is standard practice to study the lensing of gravitational waves (GW) using the geometric optics regime. However, in many astrophysical configurations this regime breaks down as…
Tensor instabilities at the end of the LCDM universe
Giulia Cusin, Filipe de O. Salles, Ilya L. Shapiro
The unphysical spin-2 massive degrees of freedom in higher derivative gravity may be either massive unphysical ghosts or tachyonic ghosts. In the last case there is no Planck-scale…
