Years after the collapse of the SETI) Institute, data from the observatory was utilised to uncover new details about pulsar signals. These dense neutron stars emit beams of radiation likened to "cosmic lighthouses," and their signals undergo distortions as they traverse the interstellar medium. Findings from this research were published in The Astrophysical Journal on November 26.

Pulsar Signals and Interstellar Scintillation 58c

The phenomena called diffractive interstellar scintillation (DISS). This phenomenon, which resembles the rippling patterns caused by light ing through water, is attributed to interactions between pulsar signals and charged particles in space.

Implications for Gravitational Wave Studies s2f5f

Reportedly, a better understanding of pulsar signal distortions could enhance projects like the North American Nanohertz Observatory for Gravitational Waves (NANOGrav), which employs pulsar timing arrays to detect space-time distortions caused by gravitational waves. The recent identification of the gravitational wave background, potentially originating from supermassive black hole mergers, underscores the relevance of such advancements.
