      Comunicació de congrés
      Accés restringit per política de l'editorial
      Results of heart rate variability analysis depend on the quality of the initial RR time series that is measured only in one lead of the ECG. This work shows that RR time series can subtly change from lead ...

      Accés obert
      The LISA PathfinderDMU(Data Management Unit) flight model was formally accepted by ESA andASDon 11 February 2010, after all hardware and software tests had been successfully completed. The diagnostics items are scheduled to ...

    • Tilt-to-length coupling in LISA Pathfinder: a data analysis 

      Armano, M.; Audley, H.; Baird, J.; Binetruy, P.; Born, M.; Bortoluzzi, D.; Castelli, Eleonora; Cavalleri, A.; Cesarini, A.; Cruise, M.; Danzmann, K.; de Deus Silva, Marcus; Diepholz, I; Dixon, G.; Dolesi, R; Ramos Castro, Juan José (American Physical Society, 2023-11-15)
      Article
      Accés obert
      We present a study of the tilt-to-length coupling noise during the LISA Pathfinder mission and how it depended on the system’s alignment. Tilt-to-length coupling noise is the unwanted coupling of angular and lateral ...

    • Transient acceleration events in LISA Pathfinder data: properties and possible physical origin 

      Armano, M.; Audley, H.; Baird, J.; Binetruy, P.; Born, M.; Bortoluzzi, D.; Castelli, Eleonora; Cavalleri, A.; Cesarini, A.; Chiavegato, Vittorio; Cruise, M.; Dal Bosco, Davide; Danzmann, K.; De Deus Silvia, Marcus; Diepholz, I; Ramos Castro, Juan José (American Physical Society, 2022-09-12)
      Article
      Accés obert
      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 ...
