Abstract
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 characterization of this noise source in the LISA Pathfinder optical bench and propose a method to remove its contribution from the data. Our results show that temperature fluctuations are indeed limiting our measurement below one millihertz, and that their subtraction leads to a factor 5.6 (15 dB) reduction in the noise level at the lower end of the LISA measurement band (104 Hz), which increases to 20.2 (26 dB) at even lower frequencies, i.e., 1.5×105 Hz. The method presented here can be applied to the subtraction of other noise sources in gravitational-wave detectors in the general situation where multiple sensors are used to characterize the noise source.
