A summary of searches for heavy resonances decaying to a pair of bosons is presented, using pp collision data at $\sqrt{s} =$ 13 TeV collected by the CMS detector at the LHC during 2016. A striking feature common to most of these analyses is their boosted topology, in which the decay products of the considered bosons (both electroweak W and Z bosons and the Higgs boson) are expected to be highly energetic and close in angle, requiring a non-trivial identification of the final-state particles. The exploitation of jet substructure techniques allows an increase of the sensitivity of the searches where at least one boson decays hadronically. Various background estimation techniques are utilized, either based on hybrid data-simulation approaches or only relying on control regions in data. The data are found to be consistent with the background expectations, and the results are interpreted in the context of the bulk graviton and heavy vector triplet models.
