Detection and characterization of instrumental transients in <i>LISA Pathfinder</i> and their projection to LISA

The LISA Pathfinder (LPF) mission succeeded outstandingly in demonstrating key technological aspects of future space-borne gravitational-wave detectors, such as the Laser Interferometer Space Antenna (LISA). Specifically, LPF demonstrated with unprecedented sensitivity measurement relative acceleration two free-falling cubic test masses. Although most disruptive non-gravitational forces have been identified and their effects mitigated through a series calibration processes, some faint transient signals yet unexplained origin remain measurements. If they appear data, these perturbations (also called glitches) could skew characterization sources or even be confused bursts. For first time, we provide comprehensive census events. Our analysis is based on phenomenological shapelet model allowing us to derive simple statistics about physical features glitch population. We then implement generator synthetic glitches designed used for subsequent studies, perform preliminary evaluation effect data analyses.
