    WSClean

    WSClean is a fast widefield interferometric imager

    WSClean (w-stacking clean) is a fast generic widefield imager. It uses the w-stacking algorithm and can make use of the w-snapshot algorithm. As of Feb 2014, it is 2-12 times faster than CASA's w-projection, depending on the array configuration. It supports full-sky imaging and proper beam correction for homogeneous dipole arrays such as the MWA. WSClean allows Hogbom and Cotton-Schwab cleaning and has wideband, multiscale, compressed sensing and joined-polarization deconvolution modes. ...

    As of August 2018 Spheral++ has moved to Github -- please see the current repository at https://github.com/jmikeowen/spheral We are leaving a frozen version here on SourceForge for historical reasons. Spheral++ provides a steerable parallel environment for performing coupled hydrodynamical & gravitational numerical simulations. Hydrodynamics and gravity are modelled using particle based methods (SPH and N-Body).

    astronx

    simulation of objects in space with classical mechanics

    astronx simulates the motion of mass-centres in cartesian space. The mass-centres interact solely through gravity. astronx uses the Bulirsch-Stoer extrapolation algorithm with adaptive stepsize to integrate the newtonian equations of motion.

    FreDec

    Parallelized FREquency DEComposer algorithm

    This is a parallelized algorithm performing a decomposition of the time-series data into a number of sinusoidal components, disentangling them from the white Gaussian noise. The algorithm analyses all suspicious frequencies, including the ones that look like an alias at a glance, but may become preferable later. After selection of the initial frequency candidates, the algorithm passes through all their possible combinations and estimates their multi-frequency statistical significance. ...

    Clusterfit

    Show stellar evolution and open clusters in a color-magnitude diagram

    ...In addition, it can show the CMD of a large number of existing open clusters, based on scientific survey data, and overlay isochrones (the curve in a CMD from stars born at the same time) to determine the age, distance and interstellar reddening of the cluster. Determining these parameters can be done automatically with a global search algorithm (more specifically a genetic algorithm). This program requires the installation of the libfgen package, also available on SourceForge.
