PNe and HII regions plasma diagnostics
We carry out plasma diagnostic analyses for 123 planetary nebulae (PNe) and 42 HII regions using the NII and OII optical recombination lines (ORLs). New effective recombination... -
Binarity in planetary nebula central stars
We still do not know what causes aspherical planetary nebula (PN) morphologies. A plausible hypothesis is that they are due to the presence of a close stellar or substellar... -
Kinematics of NGC 2768 from planetary nebulae
There are only a few tracers available to probe the kinematics of individual early-type galaxies beyond one effective radius. Here we directly compare a sample of planetary... -
Deep spectroscopy of NGC 7009
We present very deep CCD spectrum of the bright, medium-excitation planetary nebula NGC 7009, with a wavelength coverage from 3040 to 11000{AA}. Traditional emission line... -
PN towards Galactic bulge. [OIII] fluxes
We present [OIII]{lambda}5007 fluxes and angular diametres for 435 Planetary Nebulae (PNe) in the central 10{deg}x10{deg} region towards the Galactic bulge. Our sample is taken... -
MASH PNe detected in large-scale radio surveys
We present an updated and newly compiled radio-continuum data base for Macquarie/AAO/Strasbourg H{alpha} (MASH) planetary nebulae (PNe) detected in the extant large-scale... -
Galactic planetary nebulae at 24{mu}m
We have obtained 24{mu}m imaging, profiles and fluxes for 224 planetary nebulae (PNe) lying within the limits of the Galactic survey undertaken with the Multiband Imaging... -
Spectrosocopy of NGC 7009
NGC 7009 is a fascinating example of a high-excitation, elliptical planetary nebula (PN) containing circumnebular rings, and FLIERs and jets along the major axis. We present... -
LMC PNe [OIII] 5007{AA} and H{beta} flux
Our previous identification and spectroscopic confirmation of 431 faint, new planetary nebulae (PNe) in the central 25deg^2^ region of the Large Magellanic Cloud (LMC) permit us... -
Infrared photometry of Galactic and MC PN
We present mid-infrared (MIR) photometry for 367 Galactic disc, bulge and Large Magellanic Cloud (LMC) planetary nebulae (PNe), determined using data acquired with the Spitzer... -
IR colours of MASH planetary nebulae
We have analysed the near-infrared (NIR) and far-infrared (FIR) colours of MASH I and MASH II (the Macquarie/AAO/Strasbourg surveys, Cat. ) planetary nebulae (PNe), using data... -
New PNe in 6 early-type galaxies
We present new planetary nebulae (PNe) positions, radial velocities and magnitudes for six early-type galaxies obtained with the Planetary Nebulae Spectrograph (PNS), along with... -
Planetary nebulae of NGC 4494
We present new Planetary Nebula Spectrograph observations of the ordinary elliptical galaxy NGC 4494, resulting in positions and velocities of 255 planetary nebulae out to seven... -
Velocities of NGC 1023 planetary nebulae
We investigate the manner in which lenticular galaxies are formed by studying their stellar kinematics: an S0 formed from a fading spiral galaxy should display similar cold... -
Complete catalog of planetary nebulae in LMC
This paper presents accurate homogeneous positions, velocities and other pertinent properties for 460 newly discovered and 169 previously known planetary nebulae (PNe) in the... -
M31 planetary nebulae velocities
We present radial velocities for a sample of 721 planetary nebulae in the disc and bulge of M31, measured using the WYFFOS fibre spectrograph on the William Herschel Telescope.... -
Kinematic survey of planetary nebulae in M31
We present a catalogue of positions, magnitudes and velocities for 3300 emission-line objects found by the Planetary Nebula Spectrograph in a survey of the Andromeda galaxy,... -
Chemical abundances for Hf 2-2
We present high-quality optical spectroscopic observations of the planetary nebula (PN) Hf 2-2. The spectrum exhibits many prominent optical recombination lines (ORLs) from... -
2MASS photometry of galactic planetary nebulae
The recently published 2MASS all-sky infrared survey () includes JHKs photometry of over 300 million sources. It also provides sizes and aspect ratios for the ~0.55 per cent of... -
Distances of planetary nebula
The distances of planetary nebulae (PNe) are still quite uncertain. Although observational estimates are available for a small proportion of PNe, based on statistical parallax...
