A DECADE of Giants: A catalog of 42,000 optically identified galaxy clusters from 13,000 of the sky

D. Anbajagane, C. To, M. Gaido +44

Galaxy clusters are sensitive to a rich variety of physics spanning a wide dynamic range, from microphysical to cosmological scales. Optical datasets are efficient at identifying c…
