Using NASA's Fermi space telescope, Chinese astronomers have investigated a newly discovered millisecond pulsar known as PSR J1835−3259B. As a result, they identified gamma-ray pulsations from this source. The finding is ...
To solve a long-standing puzzle about how long a neutron can "live" outside an atomic nucleus, physicists entertained a wild but testable theory positing the existence of a right-handed version of our left-handed universe. ...

An international team of astronomers reports the discovery of a new millisecond pulsar in the globular cluster NGC 6652. The newly found pulsar received designation PSR J1835−3259B. The study detailing the finding and disclosing ...
European astronomers have conducted a detailed, long-term X-ray monitoring campaign of a magnetar known as SGR J1935+2154, since it entered its active phase, experiencing numerous X-ray outbursts. Results of the study, published ...
