Velocities of PNe in NGC 4697
Listed in IVOA Registry (Virtual Observatory)
We describe the implementation of slitless radial velocity measurements of extragalactic planetary nebulae (PNs) with the 8.2m Subaru telescope and its Cassegrain imaging spectrograph, Faint Object Camera and Spectrograph (FOCAS).
Description
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, observed previously with the ESO VLT + FORS imaging spectrograph; 36 of these new 56 PNs are located at angular distances larger than 230 arcsec from the center of NGC 4697. We compare the new FOCAS velocities with the earlier FORS velocities, for 158 of the 162 reobserved sources, finding good agreement. We now have kinematic information extending out to five effective radii from the center.
