A startling discovery in the latest paper from the Zoo
This morning the latest paper from Galaxy Zoo appeared on astro-ph — “Galaxy Zoo: an unusual new class of galaxy cluster”. Authored by two of the Galaxy Zoo team’s newest recruits, Marven F. Pedbost and Trillean Pomalgu, this four-page paper presents a remarkable new discovery, which may require us to revise our fundamental ideas about either our place in the universe or the occurrence of unlikely events. The abstract gives a concise summary:
We have identified a new class of galaxy cluster using data from the Galaxy Zoo project. These clusters are rare, and thus have apparently gone unnoticed before, despite their unusual properties. They appear especially anomalous when the morphological properties of their component galaxies are considered. Their identification therefore depends upon the visual inspection of large numbers of galaxies, a feat which has only recently been made possible by Galaxy Zoo, together with the Sloan Digital Sky Survey. We present the basic properties of our cluster sample, and discuss possible formation scenarios and implications for cosmology.
