Can Planck constrain indirect detection of dark matter in our galaxy?
Timur Delahaye, C\'eline B{\oe}hm, Joseph Silk
TL;DR
This paper explores how Planck satellite data can be used to constrain dark matter properties by analyzing frequency-dependent synchrotron emission morphology, combining astrophysical models with Fermi data.
Contribution
It introduces a method to use Planck's multi-frequency observations to distinguish dark matter signals from astrophysical sources based on emission morphology.
Findings
Synchrotron emission morphology varies with frequency.
Comparison of LFI and HFI data can constrain dark matter particle mass.
Frequency-dependent analysis enhances dark matter detection prospects.
Abstract
We investigate the synchrotron emission (both intensity and morphology) associated with generic dark matter particles and make predictions for the PLANCK experiment using the FERMI data and a model for the astrophysical sources. Our results indicate that the morphology of the dark matter plus astrophysical source synchrotron emission is frequency-dependent. We show that a thorough comparison between LFI and HFI data can potentially provide a new tool for constraining the dark matter particle mass.
