Candidates for intracluster planetary nebulae in the virgo cluster based on the suprime-cam narrow-band imaging in [O III] and Hα

We have identified 38 candidates of intracluster planetary nebulae (ICPNe) in a 34′ 27′ field in the core of the Virgo cluster based on Suprime-Cam imaging through two narrow-band filters centered at redshifted wavelengths of the [O III] λ = 5007 Å and the Hα λ = 6563 Å lines. Broad-band images in the V and R bands are used to check for any emissions in the adjacent continuum. We describe the method briefly and present a list of the intracluster planetary nebula candidates, together with their finding charts. The ICPN candidates show a highly inhomogeneous distribution, which may suggest an association with the M 86-M 84 subcluster. The fraction of diffuse intracluster light with respect to the total light in galaxies is estimated to be about 10%, leading to an estimate of about 20% for the baryon fraction. A spectroscopic follow up and a wider survey are critical to reveal the nature of the intracluster stellar population.
