  "abstract": "We report recent results obtained with the Belle detector using a 23.6 fb^{-1} data sample collected on the Y(5S) resonance at the KEKB asymmetric energy e^+ e^- collider. Inclusive semileptonic B_s^0 -> X^+ l^- \\nu decays are studied for the first time and the branching fraction is measured. Combining the electron and muon channels, we obtain Bf(B_s^0 -> X^+ l^- \\nu) = (10.2 \\pm 0.8 \\pm 0.9)%. Also, the radiative penguin decay B_s^0 -> \\phi \\gamma is observed for the first time, and an improved upper limit for the decay B_s^0 \\to \\gamma \\gamma is obtained.",
