We present lattice nonrelativistic QCD calculations of bottomonium correlation functions at temperatures T≃150-350 MeV. The correlation functions were computed using extended bottomonium operators and on background gauge-field configurations for 2+1-flavor QCD having physical kaon and nearly physical pion masses. We analyzed these correlation functions based on simple theoretically motivated parametrizations of the corresponding spectral functions. The results of our analyses are compatible with significant in-medium thermal broadening of the ground state S- and P-wave bottomonia.
