The PDF says they used the data from the WISE all-sky infrared survey to find the 100,000 galaxies, of which a "significant population" had a redshift z of over 2. https://arxiv.org/pdf/1504.03418.pdf Depending on the Hubble constant, a z of 2 is more than 8000 mpc, 27 billion light years. That's a big search volume, and they didn't find anything obviously artificial.
