Title: An ALMA View on Hot Dust Obscured Galaxies and the Most Luminous 
Galaxy Known


ABSTRACT:
Hot Dust-Obscured Galaxies (Hot DOGs) are a new galaxy population of 
extremely obscured quasars discovered by the WISE mission. An ALMA pilot 
survey of the fine-structure [CII] line at 158um in a small sample of 
Hot DOGs at z ~ 3-4.6 reveal a diversity of morphologies and complex 
kinematics, likely reflecting the disturbed dynamical state of these 
systems, which are thought to be at a key stage of their evolution. ALMA 
has also provided us with a closer look to WISE 2246-0526, the most 
luminous galaxy known, where recent, deep observations of its 
far-infrared dust continuum emission show multiple galaxy companions 
and, for the first time, resolved filamentary structures connecting the 
neighbors to the central object.
