The brightest cluster galaxy (BCG) in the core of the rich, cluster CL0910+41 (z=0.44) is among the most infrared-luminous galaxies known. It possesses an type II quasar (the closest one to us) together with an active starburst and a radio jet. These properties make it a truly unique laboratory for probing the AGN-starburst connection. We propose to obtain GMOS long-slit spectra to help us (1) constrain the starburst history of the BCG, and (2) in combination with our GMRT data, determine the chronology of the starburst/radio jet activation. Together, the radio and optical data will help us construct a detailed snapshot of this system, including the black hole mass accretion rate, which can then be used to constrain models that seek to explain the details of the AGN/Starburst interaction. Owing to the obscuration of the central source and its close proximity to us, this system also presents a rare opportunity to examine the stellar populations around such an active region.
