Using a rotating Mach–Zehnder interferometer comparing light propagation in atmospheric air and vacuum, we have reproduced the anomalous signal residuals reported in early Michelson–Morley experiments with gas in the optical pathways. Far lower in amplitude than classical predictions and usually dismissed as instrumental systematics, these small signals were nevertheless reproducible in our modern experiment. A hitherto unsuspected feature of the signals was their pulsatile nature, revealed by digital filtering of the raw data. This characteristic, found in historical records as well as in our present experiments, is inconsistent with any purely kinematic interpretation. Amid noise of thermal origin in the signal, Fourier analysis revealed a component phase-locked to the rotation of the interferometer. This signal exhibited daily and seasonal fluctuations consistent with a celestial source at RA 21.9 h, DEC + 46.1°, close to the vector of the predicted dark matter wind and clearly separated from the cosmic microwave background dipole vector. The phenomenon warrants further investigation in theory and experiment.
