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…
A New Look at an Old Cluster: The Membership, Rotation, and Magnetic Activity of Low-Mass Stars in the 1.3-Gyr-Old Open Cluster NGC 752
Marcel Agüeros, Emily Bowsher, John Bochanski +8
The nearby open cluster NGC 752 presents a rare opportunity to study stellar properties at ages >1 Gyr. However, constructing a membership catalog for it is challenging; most surve…
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…
Fossil Group Origins VII. Galaxy substructures in fossil systems
S. Zarattini, M. Girardi, J. A. L. Aguerri +9
Fossil groups are expected to be the final product of galaxy merging within galaxy groups. In simulations, they are predicted to assemble their mass at high redshift. This early fo…
Fossil group origins V. The dependence of the luminosity function on the magnitude gap
S. Zarattini, J. A. L Aguerri, R. Sanchez-Janssen +11
In nature we observe galaxy aggregations that span a wide range of magnitude gaps between the two first-ranked galaxies of a system (). There are systems with gaps close t…
Fossil group origins - VI. Global X-ray scaling relations of fossil galaxy clusters
A. Kundert, F. Gastaldello, E. D'Onghia +11
We present the first pointed X-ray observations of 10 candidate fossil galaxy groups and clusters. With these Suzaku observations, we determine global temperatures and bolometric X…
The Factory and The Beehive II. Activity and Rotation in Praesepe and the Hyades
S. T. Douglas, M. A. Agüeros, K. R. Covey +9
Open clusters are collections of stars with a single, well-determined age, and can be used to investigate the connections between angular-momentum evolution and magnetic activity o…
