Here, we demonstrate that using this model we are also able to describe the excesses in gamma-ray flux from the galactic centre and the cosmic-ray spectra from AMS-02. This is achieved through Dark Matter (DM) annihilation via the singlet scalar. Of great interest is the flux of synchrotron emissions which results from annihilation of DM in Milky-Way satellites. We make predictions for MeerKAT observations of the nearby dwarf galaxy Reticulum~II and we demonstrate the power of this instrument as a new frontier in indirect dark matter searches.", "revisions": [ { "version": "v1", "updated": "2021-02-21T12:41:47.000Z" } ], "analyses": { "keywords": [ "connecting multi-lepton anomalies", "astrophysics", "meerkat/ska", "indirect dark matter searches", "higgs doublet model" ], "note": { "typesetting": "TeX", "pages": 8, "language": "en", "license": "arXiv", "status": "editable" } } }
