Book excerpt: Debye screening of inter-quark potentials leading to suppression of heavy quarkonia has long been a studied signature of the onset of partonic deconfinement. We report on the production of [Upsilon](1S+2S+3S) mesons at [squareroot]s(NN) = 200 GeV in p + p, d + Au, and Au + Au collisions as measured by the Solenoidal Tracker At RHIC. We compare our measured yield in p + p collisions to those in d + Au and Au + Au collisions to obtain nuclear modification factors and quantify suppression effects from both hot and cold nuclear matter. We separate our Au + Au measurements into three centrality classes. We obtain a nu- clear modification factor for [Upsilon](1S+2S+3S) in the rapidity range [vertical line]y[vertical line]
