Open Source Astronomy Software

The Universe Simulator project's goal is to provide a set of libraries for simulating all known and understood physical phenomena.

EXTREMA is an interactive program with publication quality graphics and mathematical analysis capabilities. EXTREMA can be GUI and/or command driven. The command language includes conditional branching, looping and subroutine calling constructs.

FABS is a program designed to run a fluorescence/absorption spectrometer on Windows. The program analyzes spectra and provides graphs and data files. Users may choose to input video files from cell phones or other cameras, still images, or even live streams of video from webcams. FABS can perform any necessary calibration and image preprocessing. Experienced users have a number of more advanced options such as background subtraction, adjustments for nonlinearities in detector response, and graph smoothing. FABS was designed with students in mind, as a way to help high schoolers and undergraduates learn about spectroscopy without paying for expensive equipment and software. Accompanying this software is a hardware design, which can be used as a bare-bones spectrometer that will provide quantitative absorption and fluorescence emission spectra at an extremely low cost. It uses only materials that many people can find around their home.

Java program for computations with values expressed in terms of physical or other units. Supports complicated mathematical expressions and user-defined functions. Invoked from scripts, line command, or as GUI. Extensive units data base.

Gridder is a group of portlets that simplify the use and administration of grid services. Especially for job submission management. Gridder also extends and documents the functionality of the OGCE Bundle. It is plenty of useful documentation.
