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…
Probing the Physics of Narrow Line Regions in Active Galaxies IV: Full data release of The Siding Spring Southern Seyfert Spectroscopic Snapshot Survey (S7)
Adam D. Thomas, Michael A. Dopita, Prajval Shastri +15
We present the second and final data release of the Siding Spring Southern Seyfert Spectroscopic Snapshot Survey (S7). Data are presented for 63 new galaxies not included in the fi…
Dissecting Galaxies: Separating Star Formation, Shock Excitation and AGN Activity in the Central Region of NGC 613
Rebecca L. Davies, Brent Groves, Lisa J. Kewley +13
The most rapidly evolving regions of galaxies often display complex optical spectra with emission lines excited by massive stars, shocks and accretion onto supermassive black holes…
Centrifugally driven winds from protostellar accretion discs. I - Formulation and initial results
C. A. Nolan, R. Salmeron, C. Federrath +2
Protostellar discs play an important role in star formation, acting as the primary mass reservoir for accretion onto young stars and regulating the extent to which angular momentum…
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…
Effects of Pre-ionisation in Radiative Shocks II: Application to the Herbig-Haro Objects
Michael A. Dopita, Ralph S. Sutherland
In an earlier paper we treated the pre-ionisation problem in shocks over the velocity range km/s in a fully self-consistent manner. Here we investigate in de…
