abstract

  • Abstract: Since galaxy clusters sit at the high-end of the mass function, the number of galaxy clusters both massive and concentrated enough to yield particularly large Einstein radii poses useful constraints on cosmological and structure formation models. To date, less than a handful of clusters are known to have Einstein radii exceeding $\sim40 $"(for a source at $ z_ {s}\simeq2 $, nominally). Here, we report an addition to that list of the Sunyaev-Zel'dovich (SZ) selected cluster, PLCK G287. 0+ 32.9 ($ z= 0.38$), the second-highest SZ-mass …
