Interferometer observations of pulse pairs in an interstellar communication experiment

TL;DR

This study reports interferometer observations of anomalous 3.7 Hz pulses near Rigel, supporting a celestial origin hypothesis through 123 days of phase measurements and noise analysis.

Contribution

It provides new interferometric phase measurement data and analysis to support the celestial source hypothesis of the anomalous pulses.

Findings

123 days of phase measurements support celestial origin

Simultaneous noise measurements conducted across multiple bandwidths

Evidence consistent with a celestial source of the pulse pairs

Abstract

Synchronized radio telescope-based experiments conducted since 2017, together with subsequent interferometer experiments, provide evidence of an anomalous source of 3.7 Hz bandwidth pulses, sourced from near the direction of the star Rigel. The current experiment, reported here, uses a two-element phase-measuring interferometer to monitor the hypothetical pulse source across azimuths within the beam-widths of the elements of a south-facing interferometer. 123 days of phase measurements of 3.7 Hz bandwidth pulse pairs, adds to the prior evidence that the pulsing signal source has celestial origin. Associated measurements of noise power in 954 Hz and 50 MHz bandwidths, made simultaneous with the 0.27 second duration pulse pair measurements, are presented. Measurement results are presented to aid in the development of independent experimental replication, and alternate and auxiliary explanatory hypotheses.
