Two neutrino events thought to be of atmospheric origin are consistent with one formation scenario for luminous fast blue optical transients, though follow-up searches are necessary to draw firm conclusions.

High-mass white dwarfs may attain magnetic fields through an existing dynamo, while relaxation of a magnetic field from interior to surface may explain the slow-to-appear fields of low-mass white dwarfs.

UV Ceti frequently flares at optical, ultraviolet, soft X-ray, and radio wavelengths, and researchers have now observed a 2-hour radio outburst in high spectral resolution, allowing them to assess its cause.

The new 0.7-meter robotic telescope, commissioned in 2018, will contribute to time-domain astronomy, in particular helping researchers make follow-up observations of gamma-ray burst sources.

Hidden no more: researchers have spectroscopically confirmed 204 quasars — extremely luminous galaxies powered by supermassive black holes — obscured by the galactic plane, with redshifts between 0.069 and 4.487.

Researchers report the discovery of the first millimeter-wavelength afterglow from a short gamma-ray burst and confirm the afterglow of another gamma-ray burst for which we have localized a position.
