Gigapixel GPU accelerated radio interferometric imager
ExCon can create images with a very wide field of view (more than billion pixels). It implements novel gridding and image weighting algorithms. It is well suited to make ultra deep radio interferometric images, minimizing aliasing artefacts and PSF variation. NVIDIA GPU acceleration is available. JAVA/SCALA support available.
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. In the end, it prints out the set of largest frequency tuples that were still found significant. The GPU computing is implemented through CUDA and brings a significant performance increase. It is still possible to run FreDec solely on CPU, if no suitable GPU device is available in the system. See the details of the underlying theory in Baluev 2013, MNRAS, V. 436, P. 807 The description of the algorithm itself can be found in arXiv:1309.0100. Please go to the project forum to report any bugs.

Gravitational Wave Detection Using Match-Filtering With Templates
Image stacking software for Unix/Linux, primarily for Astrophotography
Simple image stacking software for Unix/Linux, primarily for Astrophotography. Written in GTKMM (C++). Note: Currently being planned/implemented; not final working software yet.
Modelling galaxy disk shape aberration
Let suppose a galaxy to be just a disk of stars, mainly double. For each star we have an aberration -v/c which visually moves it to another position, so we view galaxy disk optically changed. This modelling allows to see which shapes we can see from different distances for disks tilted by a certain angle.

Experimental OpenGl night sky rendering by making full use of modern PCs hardware. Writing another planetarium is crazy? It's Glunatic!
Gravitation is an interactive program, which tries to simulate the dynamics of celestial objects in their mutual gravitational field.
GravitySim is an application written in C# using Microsofts Windows.Forms for the GUI. It allows the user to place point masses on a coordinate map, and given velocity, calculates the orbits of the masses, representing it graphically.
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.
GyVe (GalaxY ViEwer) is a visualization program for understanding the distribution of galaxies and clusters of galaxies.
Educational astrometry utility for plotting stars on a Hertzsprung-Russel diagram. Useful for learning about stellar spectra and properties and performing spectroscopic parallax calculations, as found in many high school physics courses.
