High-cadence GW astrometry in the Hz gap
Giorgio Mentasti, Carlo Contaldi
We forecast the sensitivity of a dedicated, fast-spinning astrometric survey to a stochastic gravitational-wave background (SGWB) in the microhertz gap between pulsar timing arrays…
An explicit and differentiable Wilson-Daubechies-Meyer transform for gravitational-wave data analysis
Avi Vajpeyi, Giorgio Mentasti, Quentin Baghi +2
The Wilson-Daubechies-Meyer (WDM) time-frequency transform has been widely used in gravitational-wave astronomy, yet a self-contained, mathematically explicit reference for practit…
Sachs-Wolfe effect as a smoking gun for cosmological gravitational wave backgrounds
Giorgio Mentasti, Leon Vidal, Quentin Baghi +1
The Sachs-Wolfe (SW) effect, arising from large-scale structures in the universe, modifies the frequencies of gravitational waves (GWs) sourced by a cosmological background. We sho…
Cross-correlating Astrometric and Timing Residuals to Constrain Stochastic Gravitational-Wave Backgrounds
Elias Fink, Carlo Contaldi, Giorgio Mentasti
We investigate the cross-correlation between astrometric and timing-residual observables for distant sources, such as pulsars and galaxies, and equivalent observables for nearby so…
Searching for Gravitational Waves with Gaia and its Cross-Correlation with PTA: Absolute vs Relative Astrometry
Massimo Vaglio, Mikel Falxa, Giorgio Mentasti +5
Astrometric missions like Gaia provide exceptionally precise measurements of stellar positions and proper motions. Gravitational waves traveling between the observer and distant st…
Covariant diffusion and drift of the stochastic GW background with LISA
Giorgio Mentasti, Arad Nasiri
We study the covariant diffusion and drift of massless particles on the light cone within the context of quantum gravity phenomenology. Unlike modified dispersion relations that vi…
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…
Probing the galactic and extragalactic gravitational wave backgrounds with space-based interferometers
Giorgio Mentasti, Carlo R. Contaldi, Marco Peloso
We employ the formalism developed in \cite{Mentasti:2023gmg} and \cite{Bartolo_2022} to study the prospect of detecting an anisotropic Stochastic Gravitational Wave Background (SGW…
Observing gravitational waves with solar system astrometry
Giorgio Mentasti, Carlo R. Contaldi
The subtle influence of gravitational waves on the apparent positioning of celestial bodies offers novel observational windows. We calculate the expected astrometric signal induced…
Prospects for detecting anisotropies and polarization of the stochastic gravitational wave background with ground-based detectors
Giorgio Mentasti, Carlo Contaldi, Marco Peloso
We build an analytical framework to study the observability of anisotropies and a net chiral polarization of the Stochastic Gravitational Wave Background (SGWB) with a generic netw…
Intrinsic limits on the detection of the anisotropies of the Stochastic Gravitational Wave Background
Giorgio Mentasti, Carlo R. Contaldi, Marco Peloso
For any given network of detectors, and for any given integration time, even in the idealized limit of negligible instrumental noise, the intrinsic time variation of the isotropic…
