The extended Planetary Nebula Spectrograph (ePN.S) early-type galaxy survey. The kinematic diversity of stellar halos and the relation between halo transition scale and stellar mass
C. Pulsoni, O. Gerhard, M. Arnaboldi +14
In the hierarchical two-phase formation scenario, the extended halos of early type galaxies (ETGs) are expected to have different physical properties from those of the galaxies' ce…
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…
The halo of M49 and its environment as traced by planetary nebulae
J. Hartke, M. Arnaboldi, A. Longobardi +4
The galaxy M49 (NGC 4472) is the brightest early-type galaxy in the Virgo Cluster. It is located in Subcluster B and has an unusually blue, metal-poor outer halo. Planetary nebulae…
