A census of baryons in the Universe from localized fast radio bursts
More than three-quarters of the baryonic content of the Universe resides in a highly diffuse
state that is difficult to detect, with only a small fraction directly observed in galaxies and …

Constraints on dark matter properties from observations of Milky Way satellite galaxies
We perform a comprehensive study of Milky Way (MW) satellite galaxies to constrain the
fundamental properties of dark matter (DM). This analysis fully incorporates inhomogeneities …

A single fast radio burst localized to a massive galaxy at cosmological distance
Fast radio bursts (FRBs) are brief radio emissions from distant astronomical sources. Some
are known to repeat, but most are single bursts. Nonrepeating FRB observations have had …
