Spaxel Analysis: Probing the Physics of Star Formation in Ultraluminous Infrared Galaxies
Michael A. Dopita, Jeffrey Rich, Frédéric P. A. Vogt +5
This paper presents a detailed spectral pixel (spaxel) analysis of the ten Luminous Infrared Galaxies (LIRGs) previously observed with the Wide Field Spectrograph (WiFeS), an integ…
Nebular metallicities in two isolated Local Void dwarf galaxies
David C. Nicholls, Helmut Jerjen, Michael A. Dopita +1
Isolated dwarf galaxies, especially those situated in voids, may provide insight into primordial conditions in the Universe and the physical processes that govern star formation in…
New Strong Line Abundance Diagnostics for \HII Regions: Effects of -Distributed Electron Energies and New Atomic Data
Michael A. Dopita, Ralph S. Sutherland, David C. Nicholls +2
Recently, \citet{Nicholls12}, inspired by \emph{in situ} observations of solar system astrophysical plasmas, suggested that the electrons in \HII regions are characterised by a …
The Cosmic BPT Diagram: Confronting Theory with Observations
Lisa J. Kewley, Christian Maier, Kiyoto Yabe +4
We compare a large sample of galaxies between 0.5<z<2.6 with theoretical predictions for how the optical diagnostic line ratios in galaxy ensembles change as a function of cosmic t…
Theoretical Evolution of Optical Strong Lines across Cosmic Time
Lisa J. Kewley, Michael A. Dopita, Claus Leitherer +5
We use the chemical evolution predictions of cosmological hydrodynamic simulations with our latest theoretical stellar population synthesis, photoionization and shock models to pre…
Measuring nebular temperatures: the effect of new collision strengths with equilibrium and kappa-distributed electron energies
David C. Nicholls, Michael A. Dopita, Ralph S. Sutherland +2
In this paper we develop tools for observers to use when analysing nebular spectra for temperatures and metallicities, with two goals: to present a new, simple method to calculate…
