Étale motivic spectra and Voevodsky’s convergence conjecture

We prove a new convergence result for the slice spectral sequence, following work by Levine and Voevodsky. This verifies a derived variant of Voevodsky's conjecture on convergence of the slice spectral sequence. This is, in turn, a necessary ingredient for our main theorem: a Thomason-style \'etale descent result for the Bott-inverted motivic sphere spectrum, which generalizes and extends previous \'etale descent results for special examples of motivic cohomology theories. Combined with first author's \'etale rigidity results, we obtain a complete structural description of the \'etale motivic stable category.
