The Line-of-Sight Velocity Distributions of Intracluster Planetary Nebulae in the Virgo Cluster Core
Radial velocities of 40 intracluster planetary nebulae (ICPNs) in the Virgo Cluster were obtained with the new multifiber FLAMES spectrograph on UT2 at the Very Large Telescope. For the first time, the λ4959 line of the [O III] doublet is seen in a large fraction (50%) of ICPNs spectra, and a large fraction of the photometric candidates with m(5007
