Free-flight experiments in LISA Pathfinder
M. Armano, H. Audley, G. Auger +89
The LISA Pathfinder mission will demonstrate the technology of drag-free test masses for use as inertial references in future space-based gravitational wave detectors. To accomplis…
Data series subtraction with unknown and unmodeled background noise
Stefano Vitale, Giuseppe Congedo, Rita Dolesi +20
LISA Pathfinder (LPF), ESA's precursor mission to a gravitational wave observatory, will measure the degree to which two test-masses can be put into free-fall, aiming to demonstrat…
Bayesian Model Selection for LISA Pathfinder
Nikolaos Karnesis, Miquel Nofrarias, Carlos F. Sopuerta +11
The main goal of the LISA Pathfinder (LPF) mission is to fully characterize the acceleration noise models and to test key technologies for future space-based gravitational-wave obs…
Subtraction of temperature induced phase noise in the LISA frequency band
M. Nofrarias, F. Gibert, N. Karnesis +4
Temperature fluctuations are expected to be one of the limiting factors for gravitational wave detectors in the very low frequency range. Here we report the characterisation of thi…
State-space modelling for heater induced thermal effects on LISA Pathfinder's Test Masses
Ferran Gibert, Miquel Nofrarias, Marc Diaz-Aguiló +7
The OSE (Offline Simulations Environment) simulator of the LPF (LISA Pathfinder) mission is intended to simulate the different experiments to be carried out in flight. Amongst thes…
Analysis of the residual force noise for the LISA Technology Package
Luigi Ferraioli, Michele Armano, Giuseppe Congedo +10
The analysis of the noise sources perturbing a test mass (TM) geodesic motion is the main scientific objective of the LISA Technology Package experiment (LTP) on board of the LISA…
Quantitative Analysis of LISA Pathfinder Test Mass Noise
Luigi Ferraioli, Martin Hewitson, Giuseppe Congedo +4
In this paper we discuss two main problems associated with the analysis of the data from LISA Pathfinder (LPF): i) Excess noise detection and ii) Noise parameter identification. Th…
Parameter estimation in LISA Pathfinder operational exercises
M. Nofrarias, L. Ferraioli, G. Congedo +6
The LISA Pathfinder data analysis team has been developing in the last years the infrastructure and methods required to run the mission during flight operations. These are gathered…
From laboratory experiments to LISA Pathfinder: achieving LISA geodesic motion
F Antonucci, M Armano, H Audley +98
This paper presents a quantitative assessment of the performance of the upcoming LISA Pathfinder geodesic explorer mission. The findings are based on the results of extensive groun…
The LISA PathFinder DMU and Radiation Monitor
Priscilla Canizares, Aleix Conchillo, Marc Diaz--Aguilo +11
The LISA PathFinder DMU (Data Management Unit) flight model was formally accepted by ESA and ASD on 11 February 2010, after all hardware and software tests had been successfully co…
Bayesian parameter estimation in the second LISA Pathfinder Mock Data Challenge
M. Nofrarias, C. Röver, M. Hewitson +6
A main scientific output of the LISA Pathfinder mission is to provide a noise model that can be extended to the future gravitational wave observatory, LISA. The success of the miss…
Calibrating spectral estimation for the LISA Technology Package with multichannel synthetic noise generation
Luigi Ferraioli, Gerhard Heinzel, Martin Hewitson +4
The scientific objectives of the Lisa Technology Package (LTP) experiment, on board of the LISA Pathfinder mission, demand for an accurate calibration and validation of the data an…
The diagnostics subsystem on board LISA PathFinder and LISA
P Canizares, A Conchillo, E Garcia-Berro +9
The Data and Diagnostics Subsystem of the LTP hardware and software are at present essentially ready for delivery. In this presentation we intend to describe the scientific and tec…
Thermal diagnostic of the Optical Window on board LISA Pathfinder
M. Nofrarias, A. F. Garcia Marin, A. Lobo +4
Vacuum conditions inside the LTP Gravitational Reference Sensor must comply with rather demanding requirements. The Optical Window (OW) is an interface which seals the vacuum enclo…
In-flight Diagnostics in LISA Pathfinder
Alberto Lobo, Miquel Nofrarias, Juan Ramos-Castro +14
LISA PathFinder (LPF) will be flown with the objective to test in space key technologies for LISA. However its sensitivity goals are, for good reason, one order of magnitude less t…
LISA and LISA PathFinder, the endeavour to detect low frequency GWs
Henrique Araujo, Cesar Boatella, Mokhtar Chmeissani +13
This is a review about LISA and its technology demonstrator, LISA PathFinder. We first describe the conceptual problems which need to be overcome in order to set up a working inter…
On-ground tests of LISA PathFinder thermal diagnostics system
Alberto Lobo, Miquel Nofrarias, Juan Ramos-Castro +1
Thermal conditions in the LTP, the LISA Technology Package, are required to be very stable, and in such environment precision temperature measurements are also required for various…
