SMART (Spectral energy distributions Markov chain Analysis with Radiative Transfer models) is a publicly available open-source spectral energy distribution (SED) fitting code. Implementing a Bayesian Markov chain Monte Carlo method, SMART fits the ultraviolet to millimetre SEDs of galaxies exclusively with radiative transfer models that currently constitute four types of pre-computed libraries, which describe the starburst, active galactic nucleus torus, host galaxy and polar dust components.
SMART promises to be a useful tool for studying galaxy evolution in the JWST era. The code is developed in PYTHON and is available on the Astrophysics Source Code Library or on GitHub. According to Oxford University Press, the article describing SMART is amongst the most-read recent articles in Monthly Notices of the Royal Astronomical Society.
