KINEMATICS OF PLANETARY NEBULAE IN THE OUTSKIRTS OF THE ELLIPTICAL GALAXY NGC 4697
We describe the implementation of slitless radial velocity measurements of extragalactic planetary nebulae (PNs) with the 8.2 m Subaru telescope and its Cassegrain imaging spectrograph, Faint Object Camera and Spectrograph (FOCAS). As a first application, we have extended a previous search for PNs in NGC 4697 to larger angular distances from its center. A total of 218 PNs were detected, and their radial velocities were measured. We have added 56 new PN detections to the existing sample of 535,doi:10.1088/0004-637x/691/1/228 fatcat:czldvaoiynattnikkl5paarbtu
