Design of Dedicated Tilt-to-Length Calibration Maneuvers for LISA
Henry Wegener, Sarah Paczkowski, Marie-Sophie Hartig +3
Tilts of certain elements within a laser interferometer can undesirably couple into measurements as a form of noise, known as tilt-to-length (TTL) coupling. This TTL coupling is an…
Post-processing subtraction of tilt-to-length noise in LISA in the presence of gravitational wave signals
Marie-Sophie Hartig, Sarah Paczkowski, Martin Hewitson +2
The Laser Interferometer Space Antenna (LISA) will be the first space-based gravitational wave (GW) observatory. It will measure gravitational wave signals in the frequency regime…
Tilt-To-Length Coupling in LISA -- Uncertainty and Biases
Marie-Sophie Hartig, Joshua Marmor, Daniel George +2
The coupling of the angular jitter of the spacecraft and their sub-assemblies with the optical bench and the telescope into the interferometric length readout will be a major noise…
Tilt-to-length coupling in LISA Pathfinder: long-term stability
M Armano, H Audley, J Baird +75
The tilt-to-length coupling during the LISA Pathfinder mission has been numerically and analytically modeled for particular timespans. In this work, we investigate the long-term st…
Precision measurements of the magnetic parameters of LISA Pathfinder test masses
M Armano, H Audley, J Baird +76
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. Magneti…
Magnetic-induced force noise in LISA Pathfinder free-falling test masses
M Armano, H Audley, J Baird +76
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 sen…
NanoNewton electrostatic force actuators for femtoNewton-sensitive measurements: system performance test in the LISA Pathfinder mission
M Armano, H Audley, J Baird +87
Electrostatic force actuation is a key component of the system of geodesic reference test masses (TM) for the LISA orbiting gravitational wave observatory and in particular for per…
Tilt-to-length coupling in LISA Pathfinder: a data analysis
M Armano, H Audley, J Baird +76
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 unwan…
Tilt-to-length coupling in LISA Pathfinder: analytical modelling
Marie-Sophie Hartig, Gudrun Wanner
Tilt-to-length coupling was the limiting noise source in LISA Pathfinder between 20 and 200 mHz before subtraction in post-processing. To prevent the adding of sensing noise to the…
Charging of free-falling test masses in orbit due to cosmic rays: results from LISA Pathfinder
LISA Pathfinder Collaboration, M. Armano, H. Audley +72
A comprehensive summary of the measurements made to characterize test mass charging due to the space environment during the LISA Pathfinder mission is presented. Measurements of th…
Non-geometric tilt-to-length coupling in precision interferometry: mechanisms and analytical descriptions
Marie-Sophie Hartig, Sönke Schuster, Gerhard Heinzel +1
This paper is the second in a set of two investigating tilt-to-length (TTL) coupling. TTL describes the cross-coupling of angular or translational jitter into an interferometric ph…
Geometric tilt-to-length coupling in precision interferometry: mechanisms and analytical descriptions
Marie-Sophie Hartig, Sönke Schuster, Gudrun Wanner
Tilt-to-length coupling is a technical term for the cross-coupling of angular or lateral jitter into an interferometric phase signal. It is an important noise source in precision i…
LION :Laser Interferometer On the mooN
Pau Amaro-Seoane, Lea Bischof, Jonathan J. Carter +2
Gravitational wave astronomy has now left its infancy and has become an important tool for probing the most violent phenomena in our universe. The LIGO/Virgo-KAGRA collaboration op…
Spacecraft and interplanetary contributions to the magnetic environment on-board LISA Pathfinder
M. Armano, H. Audley, J. Baird +79
