Abstract
Abstract With a new multi-slit imaging spectroscopy (MSIS) technique pioneered at the 8.2 m Subaru telescope and the Faint Object Camera and Spectrograph, we detect and measure the line-of-sight velocities of 40 intracluster planetary nebula candidates associated with the diffuse intracluster population of stars in the Coma cluster core, at nearly 100 Mpc distance. We describe the method for extracting the single two-dimensional spectra from the MSIS image, discuss the criteria for the identification of the emission line objects, and describe the procedure to compute their $\alpha, \delta$ (J2000) coordinates. We present the catalog of the intracluster planetary nebula candidates, their spatial location in the surveyed field, and their distribution in the velocity–magnitude plane. Finally, we comment on possible population effects and the use of these planetary nebulae to confirm the distance to the Coma cluster.
