Detection of Intracluster Planetary Nebulae in the Coma Cluster

Gerhard, Ortwin; Arnaboldi, Magda; Freeman, Kenneth; Kashikawa, Nobunari; Okamura, Sadanori; Yasuda, Naoki


[O III] X5007 emission lines of 16 intracluster planetary nebula (PN) candidates in the Coma Cluster were detected with a multislit imaging spectroscopy technique using the Faint Object Camera and Spectrograph on the Subaru telescope. The identification of these faint emission sources as PNs is supported by (1) their pointlike flux distribution in both space and wavelength, with tight limits on the continuum flux; (2) the identification of the second [O in] X4959 line in the only object at high...[Show more]
