Astronomers have investigated an ultraslow radio pulsar known as PSR J0901-4046, finding that it has an extremely high magnetic field—at a level of 30 quadrillion Gauss. The discovery, published April 7 in Physical Review ...
After upgrading the radio telescope array at Westerbork, The Netherlands, astronomers have found five new fast radio bursts. The telescope images, much sharper than previously possible, revealed that multiple bursts had pierced ...

By analyzing the data from the Hubble Space Telescope (HST), astronomers from the University of Bologna in Italy and elsewhere have found that the millisecond pulsar PSR J1835−3259B has a young white dwarf companion. The ...
When neutron stars collide they produce an explosion that is, contrary to what was believed until recently, shaped like a perfect sphere. Although how this is possible is still a mystery, the discovery may provide a new key ...

Using NASA's Swift spacecraft and ESA's XMM-Newton satellite, astronomers have observed NGC 5907 ULX1—the most luminous ultra-luminous X-ray pulsar known to date. Results of the observational campaign, published February ...
Using the Australia Telescope Compact Array (ATCA), astronomers from Hong Kong and Australia have performed radio observations of a nearby pulsar wind nebula (PWN) powered by the pulsar PSR B1706−44. Results of the study, ...
Using various space telescopes, astronomers have performed X-ray observations of a radio pulsar known as PSR J1420−6048. Results of the observational campaign, published January 27 on the arXiv pre-print server, shed more ...
Researchers using MeerKAT in South Africa have discovered nine millisecond pulsars, most of them in rare and sometimes unusual binary systems, as the first result of a targeted survey. An international team with significant ...
