TL;DR

This paper provides a comprehensive set of extinction curves for various simple galactic geometries, calculated across a broad parameter space to aid in modeling dust effects in galaxy spectra.

Contribution

It offers an extensive, finely-gridded database of galactic extinction curves using the Hyperion radiative transfer code, expanding on previous work.

Findings

Extinction curves tabulated over a broad range of parameters

Results available as an accessible HDF5 dataset

Enhanced utility for synthetic galaxy surveys

Abstract

We calculate the net extinction of galactic light as a function of wavelength, inclination, central optical depth, and morphology for simple galactic geometries using the Hyperion radiative transfer code. Compared to previous, similar works we tabulate extinction over a much broader range of galactic properties, and using a much finer grid in the model parameters. We expect these results to be useful for constructing dust-extinguished spectra and luminosities of model galaxies and, therefore, for synthetic survey building.
