Cooling functions for low-density astrophysical plasmas
The cooling functions for a plasma slab are investigated under equilibrium and nonequilibrium conditions, over a range of 10 4 -10 8.5 K and for a range of abundances. Radiative transfer and diffuse…
Theoretical Modeling of Starburst Galaxies
We have modeled a large sample of infrared starburst galaxies using both the PEGASE v2.0 and STARBURST99 codes to generate the spectral energy distribution (SED) of the young star clusters. PEGASE…
The MAPPINGS III Library of Fast Radiative Shock Models
We present a new library of fully-radiative shock models calculated with the MAPPINGS III shock and photoionization code. The library consists of grids of models with shock velocities in the range…
THEORETICAL EVOLUTION OF OPTICAL STRONG LINES ACROSS COSMIC TIME
We use the chemical evolution predictions of cosmological hydrodynamic simulations with our latest theoretical stellar population synthesis, photoionization, and shock models to predict the strong…
Spectral Signatures of Fast Shocks. I. Low-Density Model Grid
NEW STRONG-LINE ABUNDANCE DIAGNOSTICS FOR H II REGIONS: EFFECTS OF κ-DISTRIBUTED ELECTRON ENERGIES AND NEW ATOMIC DATA
Recently, Nicholls et al., inspired by in situ observations of solar system astrophysical plasmas, suggested that the electrons in H II regions are characterized by a κ-distribution of energies…
Spectral Signatures of Fast Shocks. II. Optical Diagnostic Diagrams
Chemical abundances in high-redshift galaxies: a powerful new emission line diagnostic
This Letter presents a new, remarkably simple diagnostic specifically designed to derive chemical abundances for high redshift galaxies. It uses only the Hα$\mathrm{H}\alpha$, [N ii] and [S ii]…
DUSTY, RADIATION PRESSURE-DOMINATED PHOTOIONIZATION. I. MODEL DESCRIPTION, STRUCTURE, AND GRIDS
M. D. acknowledges the support of the Australian National University and of the Australian Research Council through his ARC Australian Federation Fellowship, and M. D. and R. S. acknowledge…
A Theoretical Recalibration of the Extragalactic HII Region Sequence
We have theoretically recalibrated the extragalactic H II region sequence and defined the theoretical boundary between objects excited by stars, and those exited by active galactic nuclei. We used…
