From nice friendly volcanoes — by which I mean deadly liquid mounds of moving rock — we now jump back out to the farther corners of the universe and look at the vast number of the galaxies between here and there. The Dark Energy Survey has released 29 new scientific papers from their collaboration of 400 scientists spread across 25 institutions in seven countries. This mound of papers looks at the distribution of 226 million galaxies, their morphologies, and the structures they combine to form throughout a seven billion light-year deep cone of the universe.
To be honest, with this many papers by this many authors, I’m not sure there is a galaxy-focused researcher who isn’t either on one of these papers or reviewed one of these papers.
Over the seven billion years observed in this survey, the distribution of galaxies became more and more clustered, with the degree of clustering reflecting the amount of dark ...
