Detection and characterization of instrumental transients in LISA Pathfinder and their projection to LISA
Baghi, Quentin; Korsakova, Natalia; Slutsky, Jacob +3 more
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 the measurement of the relative acceleration of two free-falling cubic test mas…
Transient acceleration events in LISA Pathfinder data: Properties and possible physical origin
Mendes, L.; Russano, G.; Nofrarias, M. +79 more
We present an in depth analysis of the transient events, or glitches, detected at a rate of about one per day in the differential acceleration data of LISA Pathfinder. We show that these glitches fall in two rather distinct categories: fast transients in the interferometric motion readout on one side, and true force transient events on the other. …
Sensor noise in LISA Pathfinder: An extensive in-flight review of the angular and longitudinal interferometric measurement system
Mendes, L.; Russano, G.; Sanjuan, J. +84 more
In a previous article [1], we have reported on the first subpicometer interferometer flown in space as part of ESA's LISA Pathfinder mission, and have shown the residual sensor noise to be on the level of 32.0-1.7+2.4 fm /√{Hz } . This review provides a deeper and more complete overview of the full system and its interferomet…
Bridging the gap between Monte Carlo simulations and measurements of the LISA Pathfinder test-mass charging for LISA
Cesarini, A.; Grimani, C.; Fabi, M. +2 more
Context. Cubic gold-platinum free-falling test masses (TMs) constitute the mirrors of future LISA and LISA-like interferometers for low-frequency gravitational wave detection in space. High-energy particles of Galactic and solar origin charge the TMs and thus induce spurious electrostatic and magnetic forces that limit the sensitivity of these int…
Figures of merit for a stochastic gravitational-wave background measurement by LISA: Implications of LISA Pathfinder noise correlations
Christensen, Nelson; Meyer, Renate; Boileau, Guillaume
An important goal of the Laser Interferometer Space Antenna (LISA) is to observe a stochastic gravitational-wave background (SGWB). A study of possible correlated noise in LISA is relevant to establish limits for this future measurement. To test noise investigation methods under somewhat realistic conditions, we use the data of LISA Pathfinder. We…
Interplanetarymedium monitoring with LISA: Lessons from LISA Pathfinder
Cesarini, A.; Grimani, C.; Telloni, D. +4 more
The Laser Interferometer Space Antenna (LISA) of the European Space Agency (ESA) will be the first low-frequency gravitational-wave observatory orbiting the Sun at 1 AU. The LISA Pathfinder (LPF) mission, aiming at testing the instruments to be located on board the LISA spacecraft (S/C), hosted, among the others, fluxgate magnetometers and a parti…
The past decade of ZERODUR glass-ceramics in space applications
Krieg, Janina; Carré, Antoine; Döhring, Thorsten +4 more
For the past four decades, ZERODUR® glass ceramics has flown on many satellites including the prominent space missions METEOSAT, Hubble Space Telescope, CHANDRA, and LISA pathfinder. Firstly, this unique material is chosen as mirror substrate for high precision optics due to its extreme thermal stability. Its near-zero thermal expansion over a wid…
