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…
Systematics in Metallicity Gradient Measurements I : Angular Resolution, Signal-to-Noise and Annuli Binning
T. -T. Yuan, L. J. Kewley, J. Rich
With the rapid progress in metallicity gradient studies at high-redshift, it is imperative that we thoroughly understand the systematics in these measurements. This work investigat…
