Title: Towards a robust exploration of the Dark Sector with Euclid and Stage-IV surveys Abstract: The next generation of galaxy surveys—Euclid, LSST, DESI, Nancy Roman, SKAO—will deliver unprecedented precision in mapping the large-scale structure (LSS) of the Universe. These datasets will probe the expansion rate, non-linear structure growth, and the cosmic matter-energy budget, providing new insights into […]

Title: Synergies between numerical relativity and an effective-one-body gravitational wave model for eccentric binary black hole systems Abstract: Orbital eccentricity in compact binaries is considered to be a key tracer of their astrophysical origin, and can be inferred from gravitational-wave observations due to its imprint on the emitted signal. For a robust measurement, accurate waveform models are […]
