Using the MeerKAT radio telescope, an international team of astronomers has detected 13 new pulsars in the globular cluster NGC 1851. Twelve of them turned out to be millisecond pulsars (MSPs). The discovery was reported ...
A new study by Jonathan Katz of Washington University in St. Louis suggests that a recently discovered periodic radio transient source, designated GLEAM-X J162759.5−523504.3, may be a rare white dwarf pulsar. The finding ...
Astronomers have performed a comprehensive study of a peculiar "black widow" millisecond pulsar known as PSR J0610−2100. Results of this research, published March 11 on the arXiv pre-print repository, deliver essential ...
Astronomers have imaged a beam of matter and antimatter that is 40 trillion miles long with NASA's Chandra X-ray Observatory. The record-breaking beam is powered by a pulsar, a rapidly rotating collapsed star with a strong ...

An international team of astronomers has performed timing observations of an eccentric millisecond pulsar known as PSR J0955−6150. Results of the observational campaign, published March 1 on the arXiv pre-print server, ...
Astronomers discovered the first exoplanets in 1992. They found a pair of them orbiting the pulsar PSR B1257+12 about 2,300 light-years from the Sun. Two years later they discovered the third planet in the system.

Turkish astronomers have inspected GLEAM-XJ162759.5–523504.3—a recently discovered pulsar with a relatively long spin period. Results of the study, published February 14 on the arXiv pre-print repository, deliver important ...
An international team of astronomers reports the detection of a new millisecond pulsar (MSP) using the Green Bank Telescope (GBT). The newfound pulsar, designated PSR J1555−2908, turns out to be one of the so-called "black ...
Using the Five-hundred-meter Aperture Spherical radio Telescope (FAST), Chinese astronomers have investigated a peculiar emission phenomena exhibited by a pulsar known as PSR B1859+07. Results of the study, published January ...
