Kinematics of planetary nebulae in the outskirts of the elliptical galaxy NGC 4697
R. H. Mendez, A. M. Teodorescu, R. -P. Kudritzki +1
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 spectrog…
A catalog of planetary nebulae in the elliptical galaxy NGC 4697
R. H. Mendez, A. M. Teodorescu, R. -P. Kudritzki
We present a catalog of 535 planetary nebulae discovered in the flattened elliptical galaxy NGC 4697, using the FORS1 Cassegrain spectrograph of the Very Large Telescope of the Eur…
Kinematic evidence for different Planetary Nebulae Populations in the elliptical galaxy NGC 4697
Niranjan Sambhus, Ortwin Gerhard, Roberto H. Mendez
We have analysed the magnitudes, kinematics and positions of a complete sample of 320 PNs in the elliptical galaxy NGC 4697. We show (i) that the PNs in NGC 4697 do not constitute…
Oxygen and neon abundances of planetary nebulae in the elliptical galaxy NGC 4697
R. H. Mendez, D. Thomas, R. P. Saglia +3
This paper presents deep spectra of 14 planetary nebulae (PNs) at a variety of angular distances from the center of the flattened elliptical galaxy NGC 4697. Both near the center a…
Intracluster Planetary Nebulae in the Virgo Cluster
K. C. Freeman, M. Arnaboldi, M. Capaccioli +8
We briefly describe the properties of the confirmed spectroscopic sample of intracluster planetary nebulae recently discovered in the Virgo cluster. We find 23 bonafide intracluste…
