IGMtransmission: A Java GUI to model the effects of the Intergalactic Medium on the colours of high redshift galaxies

arXiv:1105.6208

Abstract

IGMtransmission is a Java graphical user interface that implements Monte Carlo simulations to compute the corrections to colours of high-redshift galaxies due to intergalactic attenuation based on current models of the Intergalactic Medium. The effects of absorption due to neutral hydrogen are considered, with particular attention to the stochastic effects of Lyman Limit Systems. Attenuation curves are produced, as well as colours for a wide range of filter responses and model galaxy spectra. Alternative filter response curves and spectra may be readily uploaded. The code is freely available from http://code.google.com/p/igmtransmission. It is licensed under the GNU General Public License v.3.
