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…
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…
Heater induced thermal effects on the LTP dynamics
Ferran Gibert, Miquel Nofrarias, Alberto Lobo +7
The STOC (Science and Technology Operations Centre) simulator of the LPF (LISA PathFinder) mission is intended to provide a validation tool for the mission operations tele-commandi…
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…
Theoretical foundations for on-ground tests of LISA PathFinder thermal diagnostics
Alberto Lobo, Miquel Nofrarias, Juan Ramos-Castro +1
This paper reports on the methods and results of a theoretical analysis to design an insulator which must provide a thermally quiet environment to test on ground delicate temperatu…
Thermo-elastic induced phase noise in the LISA Pathfinder spacecraft
Ferran Gibert, Miquel Nofrarias, Nikolaos Karnesis +17
During the On-Station Thermal Test campaign of the LISA Pathfinder the data and diagnostics subsystem was tested in nearly space conditions for the first time after integration in…
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…
Inflight magnetic characterization of the test masses onboard LISA Pathfinder
Marc Diaz-Aguiló, Enrique GarcÃa-Berro, Alberto Lobo
LISA Pathfinder is a science and technology demonstrator of the European Space Agency within the framework of its LISA mission, the latter aiming to be the first space-borne gravit…
Low-frequency gravitational-wave science with eLISA/NGO
Pau Amaro-Seoane, Sofiane Aoudia, Stanislav Babak +27
We review the expected science performance of the New Gravitational-Wave Observatory (NGO, a.k.a. eLISA), a mission under study by the European Space Agency for launch in the early…
Closed loop simulations of the thermal experiments in LISA Pathfinder
Ferran Gibert, Miquel Nofrarias, Nikolaos Karnesis +6
The thermal experiments to be carried out onboard LISA Pathfinder (LPF) will provide essential information of the dependences of the instrument with respect to temperature variatio…
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…
Fake signals caused by heavy mass motions near a sensitive spherical gravitational wave antenna
Alberto Lobo, Massimo Cerdonio, Alvaro Montero
This paper analyses in quantitative detail the effect caused by a moving mass on a spherical gravitational wave detector. This applies to situations where heavy traffic or similar…
LISA Pathfinder
Michele Armano, Heather Audley, Jonathon Baird +75
Since the 2017 Nobel Prize in Physics was awarded for the observation of gravitational waves, it is fair to say that the epoch of gravitational wave astronomy (GWs) has begun. Howe…
Neural network interpolation of the magnetic field for the LISA Pathfinder Diagnostics Subsystem
Marc Diaz-Aguilo, Alberto Lobo, Enrique GarcÃa-Berro
LISA Pathfinder is a science and technology demonstrator of the European Space Agency within the framework of its LISA mission, which aims to be the first space-borne gravitational…
LISA Pathfinder Platform Stability and Drag-free Performance
Michele Armano, Heather Audley, Jonathon Baird +75
The science operations of the LISA Pathfinder mission has demonstrated the feasibility of sub-femto-g free-fall of macroscopic test masses necessary to build a LISA-like gravitatio…
eLISA: Astrophysics and cosmology in the millihertz regime
Pau Amaro-Seoane, Sofiane Aoudia, Stanislav Babak +27
This document introduces the exciting and fundamentally new science and astronomy that the European New Gravitational Wave Observatory (NGO) mission (derived from the previous LISA…
Non-Linear gravitational growth of large scale structures inside and outside standard Cosmology
Enrique Gaztanaga, Alberto Lobo
We reconsider the problem of gravitational structure formation inside and outside General Relativity (GR), both in the weakly and strongly non-linear regime. We show how these regi…
Design of the magnetic diagnostics unit onboard LISA Pathfinder
Marc Diaz-Aguiló, Ignacio Mateos, Juan Ramos-Castro +2
LISA (Laser Interferometer Space Antenna) is a joint mission of ESA and NASA which aims to be the first space-borne gravita- tional wave observatory. Due to the high complexity and…
