  "abstract": "We explain how to reconstruct the category of Artin-Tate R-motivic spectra as a deformation of the purely topological C 2 -equivariant stable category.The special fiber of this deformation is algebraic, and equivalent to an appropriate category of C 2 -equivariant sheaves on the moduli stack of formal groups.As such, our results directly generalize the cofiber of philosophy of Gheorghe, Isaksen, Wang and Xu.A key observation is that the Artin-Tate subcategory of R-motivic spectra is easier to understand than the previously studied cellular subcategory.In particular, the Artin-Tate category contains a variant of the map, which is a feature conspicuously absent from the cellular category.1.
