Arecibo Observatory scientist Dr. Benetge Perera lead a recent publication detailing the second data release of the International Pulsar Timing Array in the Monthly Notices of the Royal Astronomical Society. The release included high precision timing data of 65 millisecond pulsars, reported improvements to their timing precision, and created the most up-to-date public data release that facilitates searches for low-frequency gravitational waves and other pulsar science. Gravitational waves produced from inspiraling supermassive black hole binaries and other low frequency (nanoHz to microHz) signals affect the timing of pulsars in a correlated manner.

In a recent publication in the Journal of Geophysical Research: Planets, AO planetary lead Dr. Anne Virkki and Dr. Sriram S. Bhiravarasu of the Lunar and Planetary Institute analyzed radar images of the moon obtained by the Mini-RF instrument on-board the Lunar Reconnaissance Orbiter (LRO) to better understand anomalous radar scattering observed in some lunar craters.
