We introduce a new galaxy image decomposition tool, galphat (GALaxy PHotometric ATtributes), which is a front-end application of the Bayesian Inference Engine (bie), a parallel Markov chain Monte Carl...

The results of a study of the Large Magellanic Cloud based on near-infrared 2MASS photometry are presented. From near-infrared color-magnitude diagram, stellar populations of the LMC are identified an...
