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).

Astrophotography Image Processing: Advanced Image Stretching with the rnc-color-stretch Algorithm http://www.clarkvision.com/articles/astrophotography-rnc-color-stretch/

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. ...

N-body implementation of two important algorithm : Tree-code (Barnes-Hut) and FMM (Fast multipole Method). We provide this two algorithm with a new data structure named compressed_octree.
