NEW CONSTRAINTS ON CONTINUOUS GRAVITATIONAL WAVES FROM NEUTRON STARS

25 Dec 2020 — Our collaborations report new constraints from two searches for continuous gravitational waves emitted by neutron stars. In a first paper, the LIGO and Virgo collaborations present results from an all-sky search for continuous gravitational waves from unknown neutron stars in binary systems. In a second paper, which is the first using the full data set from the third observing run (O3), our colleagues from the KAGRA collaboration have now officially joined forces with LIGO and Virgo scientists in looking for potential signals from the enigmatic X-ray pulsar J0537-6910. This second analysis also relied on precise timing data from NASA’s X-ray telescope NICER on board the International Space Station. Read more about both works in the science summaries here and here.
