Query: Bernstein center of supercuspidal blocks   Let $\bf{ G}$ be a tamely ramified connected reductive group defined over a
non-archimedean local field $k$. We show that the Bernstein center of a tame
supercuspidal block of $\bf{ G}(k)$ is isomorphic to the Bernstein center of a
depth zero supercuspidal block of $\bf{ G}^{0}(k)$ for some twisted Levi
subgroup of $\bf{ G}^{0}$ of $\bf{ G}$.
