Description
Clusters of galaxies are the largest known gravitationally bound
structures in the Universe, with masses around 1015 M⊙,
most of it in the form of dark matter. The ground-based Imaging
Atmospheric Cherenkov Telescope MAGIC made a deep survey of the Perseus
cluster of galaxies using almost 400 h of data recorded between 2009 and
2017. This is the deepest observational campaign so far on a cluster of
galaxies in the very high energy range. We search for gamma-ray signals
from dark matter particles in the mass range between 200 GeV and 200 TeV
decaying into standard model pairs. We apply an analysis optimized for
the spectral and morphological features expected from dark matter decays
and find no evidence of decaying dark matter. From this, we conclude
that dark matter particles have a decay lifetime longer than ∼
1026 s in all considered channels. Our results improve
previous lower limits found by MAGIC and represent the strongest limits
on decaying dark matter particles from ground-based gamma-ray
instruments.
