BEAGLE (for BayEsian Analysis of GaLaxy sEds) is a tool to model and interpret galaxy spectral energy distributions (SEDs) developed by (original designer; University of Oxford), (Institut d'Astrophysique de Paris) and (University of Hertfordshire). The tool was originally published in by Jacopo Chevallard and Stephane Charlot.
BEAGLE incorporates the consistent modelling of stellar radiation and its transfer through the interstellar and intergalactic media, allowing one to build mock galaxy catalogues as well as to interpret, in a Bayesian framework, any combination of photometric and spectroscopic galaxy observations. The current version of the tool includes, among other specifics: the emission from stars and H II regions; different parametrizations of the star formation and chemical enrichment histories of galaxies, including predictions from sophisticated galaxy formation models; the effect of changes in the α-element to iron abundance ratio on galaxy spectral properties; line emission from narrow-line emitting regions within active galactic nuclei; and the accounting, within a Bayesian framework, of different instrumental effects.
BEAGLE builds upon the modeling efforts deployed within the ERC-funded (NEw frOntiers in Galaxy spectrAl modeLing) project at the Institut d'Astrophysique de Paris. The BEAGLE tool is currently under active development and will be released as an open-source project. In the meantime, if you are interested in using BEAGLE, please , describing your needs, and we will be able to provide you with a user-friendly docker installation.
