Remember the recent discovery of seven stars with unusual spectral energy distributions, initially identified as possible Dyson Spheres?

Now, we, a group of SETI astronomers at the University of Manchester (@OfficialUoM) propose an alternative: the strange characteristics of these stars may come from ‘hot DOGs’—rare, dust-rich galaxies located behind the stars, contaminating their light in the infrared.
