“Growing supermassive black holes in the late stages of galaxy mergers are heavily obscured” (Ricci et al.) has been accepted for publication in the Monthly Notices of the Royal Astronomical Society. In this paper we use NuSTAR hard X-ray observations to show that late-stage mergers are more heavily obscured by gas and dust than early stage mergers or isolated galaxies. A preprint is available on astro-ph.
Update (11 May): The paper is now available from MNRAS.
