Reclusive neutron star may have been found in famous supernova
What remains of the star that exploded just outside our galaxy in 1987? Debris has obscured scientists' view, but two of NASA's X-ray telescopes have revealed new clues.

Using NASA's NuSTAR and Swift space observatories, Indian astronomers have inspected an X-ray pulsar known as XTE J1858+034 during its outburst and identified a low-frequency quasi-periodic oscillation (QPO) from this source. ...
Astronomers report the finding of a new candidate redback millisecond pulsar (MSP) binary associated with a gamma-ray source known as 4FGL J0940.3–7610. The newly found object is a short-period compact binary exhibiting ...
A new study, led by a theoretical physicist at the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab), suggests that never-before-observed particles called axions may be the source of unexplained, ...

Using the Arecibo 305-m radio telescope, an international team of astronomers has investigated eight binary millisecond pulsars (MSPs). Results of this study, presented in a paper published December 30 on the arXiv pre-print ...
Using the Five-hundred-meter Aperture Spherical radio Telescope (FAST), astronomers from the Chinese Academy of Sciences (CAS) and elsewhere have conducted single-pulse observations of a pulsar known as PSR B1929+10. Results ...
A combination of astrophysical measurements has allowed researchers to put new constraints on the radius of a typical neutron star and provide a novel calculation of the Hubble constant that indicates the rate at which the ...

Using the Parkes radio telescope, astronomers have investigated a radio-loud magnetar known as Swift J1818.0−1607. Results of these observations, providing more insights into the properties of this magnetar, unveiling its ...
An international team of astronomers has conducted simultaneous radio and X-ray observations of the magnetar 1E 1547.0–5408 during its period of enhanced activity. In result, new X-ray and radio bursts were detected from ...
