Modulation-assisted time-delay interferometric ranging for LISA
Jean-Baptiste Bayle, Martin Staab, Samuel P. Francis +3
Laser Interferometer Space Antenna LISA represents the next frontier in gravitationalwave GW astronomy targeting the detection of millihertz gravitational signals Central to LISAs…
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…
Clock synchronization and light-travel-time estimation for space-based gravitational-wave detectors
Jan Niklas Reinhardt, Olaf Hartwig, Gerhard Heinzel
Space-based gravitational-wave detectors, such as LISA, record interferometric measurements on widely separated satellites. Their clocks are not synced actively. Instead, clock syn…
Time-delay interferometry with onboard optical delays
Jan Niklas Reinhardt, Philipp Euringer, Olaf Hartwig +3
Time-delay interferometry (TDI) is a data processing technique for space-based gravitational-wave detectors to create laser-noise-free equal-optical-path-length interferometers vir…
Ranging Sensor Fusion in LISA Data Processing: Treatment of Ambiguities, Noise, and On-Board Delays in LISA Ranging Observables
Jan Niklas Reinhardt, Martin Staab, Kohei Yamamoto +6
Interspacecraft ranging is crucial for the suppression of laser frequency noise via time-delay interferometry (TDI). So far, the effects of on-board delays and ambiguities on the L…
The influence of laser relative intensity noise in the Laser Interferometer Space Antenna
Lennart Wissel, Olaf Hartwig, Jean-Baptiste Bayle +4
LISA is an upcoming ESA mission that will detect gravitational waves in space by interferometrically measuring the separation between free-falling test masses at picometer precisio…
