“Two Separate Outflows in the Dual Supermassive Black Hole System NGC 6240” (Müller-Sánchez+) has been published in Nature. In this paper we use optical and near-infrared observations to separate the outflowing gas the center of the NGC 6240 galaxy merger into portions driven by star formation and portions driven by the actively accreting supermassive black holes. A preprint is also available.
