(Phys.org)—Astronomers have found six new extended ionized gas clouds (EIGs) in the galaxy cluster Abell 1367 (also known as the Leo Cluster). The discovery expands the current list of the cluster’s known EIGs to 11 and provides new clues about the evolution of this group of galaxies. The researchers detailed their findings in a paper published Mar. 30 on arXiv.org.
