A group of astrophysicists has notched a pair of corrections for papers on galaxy clusters, thanks to an error that affected several figures in the papers, but not the overall conclusions.
The errors came in the catalog of “mock” galaxies that first author Fabio Zandanel, a postdoc at the University of Amsterdam, created to model features that are found in clusters of galaxies. Two mistakes canceled each other out “almost perfectly,” says Zandanel, making the changes that resulted from them subtle.
Zandanel explained the errors to us:
