Astronomers Discover 18 New Pulsars Using Arecibo Telescope Data Discovery of 18 New Pulsars Astronomers from West Virginia University, in collaboration with other institutions, have identified 18 new pulsars through the Arecibo Observatory, as a part of the AO 327-MHz Drift Survey. These discoveries were outlined in a paper published on February 6. What Are Pulsars? Pulsars are rapidly rotating neutron stars with strong magnetic fields that emit beams of electromagnetic radiation. Typically identified through brief radio bursts, some pulsars are also observed in optical, X-ray and gamma-ray wavelengths. The AO327 Survey: Purpose and Scope The AO327 survey, conducted with the Arecibo telescope at 327 MHz, operated from 2010 to December 2020. Its objective was to systematically search the entire Arecibo-visible sky (declinations between-1 °  and 38° ) for pulsars and radio transients. Key Findings from the AO327 Survey By examining data from the AO327 survey, astronomers under the ...
