Results in $B_s$ physics and bottomonium spectroscopy using the Belle $\mathrm{{\rm Y}}(5\mathrm{S})$ data

The Belle experiment at KEK accumulated a $121.4{\mathrm{f}\mathrm{b}}^{-1}$ sample of $e^{+}{e}^{-}$ collisions at the $\mathrm{{\rm Y}}(5S)$ resonance. This sample provides ample opportunity for improving the understanding of both the properties of $B_s$ mesons and the spectroscopy of bottomonium states. In this article we describe the recent results obtained from the Belle $\mathrm{{\rm Y}}(5S)$ data.
