Hydrodynamical simulations tackle the problem of neutron-star glitches, which are presumed to originate at the star’s crust before transferring momentum to the star’s core.
In February 2024, the Einstein Probe spotted an X-ray flare that was later linked to a gamma-ray burst that had been observed by the Fermi Gamma-ray Burst Monitor but did not trigger an alert.
A new spectral model identified more than 4,800 possible double-lined spectroscopic binaries: binary star systems in which spectral lines from both members are visible.
Analysis of the third gravitational-wave transient catalog suggests that the purported 10–12-solar-mass gap in the masses of observed black holes does not exist.
Assessment of Vera C. Rubin Observatory survey strategies suggests that longer-duration and larger-parallax gravitational microlensing events will be discovered and characterized more efficiently.
Multi-wavelength observations of a molecular cloud reveal various star-forming structures in a range of star-formation stages, including regions where massive stars are ionizing their surroundings.
