Planetary Nebulae and their parent stellar populations. Tracing the mass assembly of M87 and Intracluster light in the Virgo cluster core
Magda Arnaboldi, Alessia Longobardi, Ortwin Gerhard
The diffuse extended outer regions of galaxies are hard to study because they are faint, with typical surface brightness of 1% of the dark night sky. We can tackle this problem by…
The build-up of the cD halo of M87 - evidence for accretion in the last Gyr
A. Longobardi, M. Arnaboldi, O. Gerhard +1
We present kinematic and photometric evidence for an accretion event in the halo of the cD galaxy M87 in the last Gyr. Using velocities for ~300 planetary nebulas (PNs) in the M87…
The outer regions of the giant Virgo galaxy M87. Kinematic separation of stellar halo and intracluster light
Alessia Longobardi, Magda Arnaboldi, Ortwin Gerhard +1
We present a spectroscopic study of 287 Planetary Nebulas (PNs) in a total area of ~0.4 deg^2 around the BCG M87 in Virgo A. With these data we can distinguish the stellar halo fro…
