Disk outflows from a newly formed black hole are shown to produce a bright signal that could power the first peak of certain double-peaked supernova light curves or another kind of transient altogether.
Researchers have performed in an in-depth study of two tidal disruption events that were selected via their radio emission and are visible at optical wavelengths, showing unprecedented intermediate-width spectral lines.
Simulations suggest that impacts between planetesimals can produce chondrules — round inclusions of once-melted silicates — similar to what is seen in meteorites.
The Vera C. Rubin Observatory will discover ~129 candidate near-Earth objects each night, necessitating careful consideration of which objects should be followed up on with other facilities.
A recent fast X-ray transient may have been due to a supernova that developed within a dense envelope of material, providing evidence that could link several types of high-energy transients.
A detailed census of 100 pulsars, including six millisecond pulsars, yields sensitive measurements of dispersion and rotation measures, polarization, timing solutions, and more.
