LISA Test Mass Glitches: Maximum Likelihood Detection & Subtraction in TDI Data

LISA Pathfinder observed several unexpected test mass acceleration events during its flight.

LISA Pathfinder observed several unexpected test mass acceleration events during its flight. These “glitches” have been attributed to sudden releases of trapped gas from within the electrode housings. We examine the effect of similar glitches on LISA’s TDI outputs, and demonstrate a maximum likelihood technique for removing them in post-processing.
