A tale of two tails and an off-centered envelope: diffuse light around the cD galaxy NGC 3311 in the Hydra I cluster
Magda Arnaboldi, Giulia Ventimiglia, Enrica Iodice +2
The formation of intracluster light and of the extended halos around brightest cluster galaxies is closely related to morphological transformation, tidal stripping, and disruption…
Stellar population and the origin of intra-cluster stars around brightest cluster galaxies: the case of NGC 3311
L. Coccato, O. Gerhard, M. Arnaboldi +1
Context. We investigate the stellar population and the origin of diffuse light around brightest cluster galaxies. Aims. We study the stellar population of the dynamically hot stell…
The unmixed kinematics and origins of diffuse stellar light in the core of the Hydra I cluster (Abell 1060)
G. Ventimiglia, M. Arnaboldi, O. Gerhard
Diffuse intracluster light (ICL) and cD galaxy halos are believed to originate from galaxy evolution and disruption. We present a kinematic study of the ICL in the Hydra I cluster…
A survey for Ly alpha galaxies at z~3.1
G. Ventimiglia, M. Arnaboldi, O. Gerhard
We describe the results of a deep survey for Ly alpha emission line galaxies at z~3.1, carried out with the multislit imaging spectroscopy (MSIS) technique, with the FORS2 spectrog…
The dynamically hot stellar halo around NGC 3311: a small cluster-dominated central galaxy
G. Ventimiglia, O. Gerhard, M. Arnaboldi +1
An important open question is the relation between intracluster light and the halos of central galaxies in galaxy clusters. Here we report results from an on going project with the…
Kinematics and line strength indices in the halos of the Coma Brightest Cluster Galaxies NGC 4874 and NGC 4889
L. Coccato, M. Arnaboldi, O. Gerhard +3
We investigate the stellar kinematics and line strength indices in the outer halos of brightest cluster galaxies (BCGs) in the Coma cluster to obtain the outer halo V_rot and sigma…
Intracluster Planetary Nebulae in the Hydra I cluster
Giulia Ventimiglia, Magda Arnaboldi, Ortwin Gerhard
Using the Multislit Imaging Spectroscopy (MSIS) technique at the FORS2 spectrograph on VLT-UT1, we have identified 60 Intracluster Planetary Nebula (ICPN) candidates associated wit…
