3937 20190128130759.0 POSTER-2019-0040 Bertrand, Bruno A Model of Massive Electromagnetism for the Detection of Topological Dark Matter through the GNSS networks 2018 2018-07-09 We formulate a new theoretical model which paves the way for methods of detection of particular types of dark matter using GNSS networks. Our model consists in a (topologically) massive version of Maxwell theory in a medium which admits topological defect solutions. Hence it describes hypothetical dark matter consisting in Earth-sized structures like monopoles, vortices or domain walls which could induce disturbances in the GNSS networks. In the future our model will then be constrained by GNSS measurements.
