Abstract
An evolutionary link between submillimeter-bright galaxies (SMGs) and quasars at the peak epoch of star formation has been proposed in light of recent observations, suggesting massive galaxies transition from a short-lived star-burst phase to an unobscured quasar phase as they evolve. I will discuss the key findings in our recent paper (Leung & Riechers 2016), placing an unusually bright type-2 quasar host SMG – SMMJ0939+8315 – in the context of the aforementioned paradigm. I will conclude with our newly obtained observations of the CO(J=1-0) line emission toward SMMJ0939+8315, making it only the second type-2 quasar with direct constraints on the cold molecular gas content and dynamics and allowing us to make inroads into addressing the question of how the different galaxy populations are related and responsible for the build-up of stellar mass and supermassive black hole in the universe, free from excitation biases.
Coffee and tea will be served 20 minutes prior to the seminar.
