The first observations by the Imaging X-ray Polarimetry Explorer of a weakly magnetized neutron star allowed researchers to place an upper limit on the object’s polarization and constrain its inclination.

A laboratory investigation of space weathering — chemical and physical processes that change the spectral properties of asteroids — suggests that the solar wind plays a dominant role in weathering.

Researchers have compiled a new catalog of 264 southern radio sources, a large portion of which have known optical and mid-infrared counterparts as well as redshift estimates.

Three-dimensional particle-in-cell simulations of a pulsar magnetosphere illuminate the pathways through which energy is dissipated as a function of the pulsar’s inclination angle, among other factors.

A new technique that can be used as a post-processing step in the analysis of astronomical images improves contrast by at least 10–20%, and further development of this technique should yield greater gains.

Ashish Kumar Meena et al 2023 ApJL 944 L6

Using JWST observations of a galaxy cluster, researchers may have glimpsed the second and third most distant individual stars ever seen, after the redshift 6.2 star Earendel discovered with Hubble.
