Precision spectral estimation at sub-Hz frequencies: closed-form posteriors and Bayesian noise projection
Lorenzo Sala, Stefano Vitale
We consider the problem of estimating cross-spectral quantities in the low-frequency regime, where long observation times limit averaging over large ensembles of periodograms, ther…

Estimate of force noise from electrostatic patch potentials in LISA Pathfinder
Stefano Vitale, Lorenzo Sala, Valerio Ferroni +1
This paper discusses force noise in LISA and LISA Pathfinder arising from the interaction of patch potentials on the test mass and surrounding electrode housing surfaces with their…
