The Planetary Nebulae Luminosity Function (PNLF): current perspectives

Roberto H. Mendez

This paper starts with a brief historical review about the PNLF and its use as a distance indicator. Then the PNLF distances are compared with Surface Brightness Fluctuations (SBF)…

The two central stars of NGC 1514: can they actually be related?

R. H. Mendez, R. P. Kudritzki, M. A. Urbaneja

The central star of the planetary nebula NGC 1514 is among the visually brightest central stars in the sky (V=9.5). It has long been known to show a composite spectrum, consisting…

Improved spectral descriptions of planetary nebulae central stars

Walter Weidmann, Roberto Mendez, Roberto Gamen

Context. At least 492 central stars of Galactic planetary nebulae (CSPNs) have been assigned spectral types. Since many CSPNs are faint, these classification efforts are frequently…

Using NMAGIC to probe the dark matter halo and orbital structure of the X-ray bright, massive elliptical galaxy, NGC 4649

Payel Das, Ortwin Gerhard, Roberto H. Mendez +2

We create dynamical models of the massive elliptical galaxy, NGC 4649, using the N-body made-to-measure code, NMAGIC, and kinematic constraints from long-slit and planetary nebula…

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…
