Here is the research paper, “The DES view of the Eridanus supervoid and the CMB Cold Spot”. “DES” is the Dark Energy Survey, a collaborative astronomical project that uses a variety of observational techniques to map the distribution of mass and dark energy in a large region of the southern sky. The CMB cold spot is an anomalously cold region in the cosmic microwave background (CMB) radiation in a 5° patch of the southern sky.
