Fossil group origins IX. Probing the formation of fossil galaxy groups with stellar population gradients of their central galaxies
E. M. Corsini, L. Morelli, S. Zarattini +7
Fossil groups (FGs) are galaxy aggregates with an extended and luminous X-ray halo, which are dominated by a very massive early-type galaxy and lack of L* objects. FGs are indeed c…

Fossil group origins: VIII RXJ075243.6+455653 a transitionary fossil group
J. A. L. Aguerri, A. Longobardi, S. Zarattini +3
It is thought that fossil systems are relics of structure formation in the primitive Universe. They are galaxy aggregations that have assembled their mass at high redshift with few…

Are fossil groups early-forming galaxy systems?
A. Kundert, E. D'Onghia, J. A. L. Aguerri
Using the Illustris cosmological simulation, we investigate the origin of fossil groups in the mass regime. We examine the formation of the t…
