A Measurement of the Contamination in [OIII] lambda 5007 Surveys of Intracluster Stars and the Surface Density of z=3.13 Ly-alpha Galaxies

Robin Ciardullo, John Feldmeier, Kara Krelove +2

We present two pieces of evidence supporting the hypothesis that the bright [OIII] lambda 5007 sources found in Virgo's intracluster space are intracluster planetary nebulae, rathe…
