Combining astrometry with pulsar timing: the first joint analysis of very low frequency gravitational waves
Lorenzo Filipello, William Beordo, Volodymyr Akhmetov +2
The pHz to sub-nHz GW regime remains largely unexplored but is crucial for mapping the early inspiral stage of SMBHBs and probing early-Universe physics. Astrometry and pulsar timi…

Low-Frequency Stochastic Gravitational-Wave Background in Gaia DR3 catalog
V. Akhmetov, L. Filipello, M. Crosta +4
We investigate the potential to detect low-frequency gravitational waves (GWs) through their imprints on the proper motions of distant quasars observed by the Gaia mission. Using a…
