Revisiting the fossil group candidates UGC 842 and NGC 6034
Raimundo Lopes de Oliveira, Eleazar Rodrigo Carrasco, Claudia Mendes de Oliveira +4
We present a new insight on NGC 6034 and UGC 842, two groups of galaxies previously reported in the literature as being fossil groups. The study is based on optical photometry and…
Cluster and cluster galaxy evolution history from IR to X-ray observations of the young cluster RX J1257.2+4738 at z=0.866
M. P. Ulmer, C. Adami, G. B. Lima Neto +8
The cosmic time around the z~1 redshift range appears crucial in the cluster and galaxy evolution, since it is probably the epoch of the first mature galaxy clusters. Our knowledge…
An optical and X-ray study of the fossil group RX J1340.6+4018
Claudia L. Mendes de Oliveira, Eduardo S. Cypriano, Renato A. Dupke +1
Fossil groups are systems with one single central elliptical galaxy and an unusual lack of luminous galaxies in the inner regions. The standard explanation for the formation of the…
