Astronomers report the discovery of two new highly scattered pulsars as part of the Australian SKA Pathfinder (ASKAP) Variables and Slow Transients (VAST) survey. The findings are detailed in a research paper published September ...
Astronomers from Curtin University in Australia and elsewhere have performed radio observations of a tidal disruption event known as AT2019azh. Results of the new study, published September 22 on the arXiv preprint server, ...
Interference from human activity has always been a sticking point in astronomical observations. Radio astronomy is notoriously sensitive to unintentional interference—hence why there are "radio silent" zones near telescopes ...
