Precision measurements of the magnetic parameters of LISA Pathfinder test masses
Mendes, L.; Russano, G.; Nofrarias, M. +76 more
A precise characterization of the magnetic properties of LISA Pathfinder free falling test-masses is of special interest for future gravitational wave observatory in space. Magnetic forces have an important impact on the instrument sensitivity in the low frequency regime below the millihertz. In this paper we report on the magnetic injection exper…
Magnetic-Induced Force Noise in LISA Pathfinder Free-Falling Test Masses
Mendes, L.; Russano, G.; Nofrarias, M. +76 more
LISA Pathfinder was a mission designed to test key technologies required for gravitational wave detection in space. Magnetically driven forces play a key role in the instrument sensitivity in the low-frequency regime, which corresponds to the measurement band of interest for future space-borne gravitational wave observatories. Magnetically induced…
Analysis and interpretation of the in-flight dynamics of a critical space mechanism
Dalla Ricca, Edoardo; Bortoluzzi, Daniele; Vignotto, Davide
The study hereby presented develops a mechatronic model of a critical space mechanism for a comprehensive interpretation of its in-flight performance. The mechanism was operated in the LISA Pathfinder European Space Agency mission, which was flown to test key technologies developed for detecting gravitational waves from space. The mission accompli…
Improved bounds on collapse models from rotational noise of the Laser Interferometer Space Antenna Pathfinder mission
Carlesso, Matteo; Vinante, Andrea; Altamura, Davide Giordano Ario
We study spontaneous wave-function collapse models, which modify the Schrödinger equation with nonlinear and stochastic terms offering a solution to the quantum measurement problem. We find that constraints on the phenomenological parameters of the continuous spontaneous localization (CSL) model can be tightened using the recent analysis of the La…
Advanced charge control dynamics simulation for the LISA gravitational reference sensor
Kenyon, Samantha Parry; Apple, Stephen; Siu, John +2 more
A gravitational wave detector in space, the Laser Interferometer Space Antenna (LISA) will be able to detect gravitational waves in the frequency range of 0.1 mHz–1 Hz, adding to humanity's knowledge of the dark cosmos. The LISA gravitational reference sensor contains a test mass (TM) and is used to determine the local inertial reference frame and…
