Description
The latest observational status of the candidate dark matter decay signal at 3.5 keV will be presented. This unidentified X-ray line is observed in multiple galaxies and galaxy clusters. Instrumental effects or plasma emission are disfavoured while the observations are consistent with a decaying dark matter interpretation. In addition to a review of the existing work, the latest developments will be discussed.
