Topological Hochschild homology of twisted group algebras

We show the topological Hochschild homology spectrum of a twisted group algebra $\text{THH}(A^{\tau }[G])$ is the Thom spectrum associated to a parametrized orthogonal spectrum $E(A,G)$. We then analyze the structure of the parametrized orthogonal spectrum $E(A,G)$ and show that it is locally trivial.
