IFU spectroscopy of southern PN VI: The extraordinary chemo-dynamics of Hen 2-111
M. A. Dopita, A. Ali, A. I. Karakas +3
In this paper we present integral field spectroscopy of the extraordinary Type I bipolar planetary nebula Hen 2-111. In the lobes we map fast moving knots of material with [N II]$λ…
IFU spectroscopy of Southern Planetary Nebulae IV: A Physical Model for IC 418
M. A. Dopita, A. Ali, R. S. Sutherland +2
We describe high spectral resolution, high dynamic range integral field spectroscopy of IC418 covering the spectral range 3300-8950Å and compare with earlier data. We determine lin…
IFU spectroscopy of southern PNe: III
A. Ali, M. A. Dopita, H. M. Basurah +3
In this paper we describe integral field spectroscopic observations of four southern Galactic Planetary Nebulae (PNe), M3-4, M3-6, Hen2-29 and Hen2-37 covering the spectral range,…
Problems for the WELS classification of planetary nebulae central stars: Self-consistent nebular modelling of four candidates
Hassan M. Basurah, Alaa Ali, Michael A. Dopita +3
We present integral field unit (IFU) spectroscopy and self-consistent photoionisation modelling for a sample of four southern Galactic planetary nebulae (PNe) with supposed weak em…
The physics and kinematics of the evolved, interacting planetary nebula PN G342.0-01.7
Alaa Ali, Morsi A. Amer, M. A. Dopita +2
Here we aim to study the physical and kinematical characteristics of the unstudied old planetary nebula (PN) PN G342.0-01.7, which shows evidence of interaction with its surroundin…
Galaxy emission line classification using 3D line ratio diagrams
Frédéric P. A. Vogt, Michael A. Dopita, Lisa J. Kewley +5
Two-dimensional (2D) line ratio diagnostic diagrams have become a key tool in understanding the excitation mechanisms of galaxies. The curves used to separate the different regions…
