RFI detector and quality analysis for astronomical radio observations
The AOFlagger is a tool that can find and remove radio-frequency interference (RFI) in radio astronomical observations. The code has been highly optimized for speed and accuracy. It is used by default for the LOFAR radio telescope and thus is in productional stage. The software can run in a fully automated way, but a graphical interface is provided to analyse results and tweak the strategy. The preferred input file format is the Casa Measurement Set (MS) format. I believe that the AOFlagger is the best available flagger, both in terms of accuracy and speed. It has been succesfully used on several interferometric telescopes, including LOFAR, WSRT, VLA, GMRT, ATCA and MWA, and the single-dish telescopes Parkes and Arecibo 305m. Besides the flagger, the software consists of tools to efficiently visualize data in different ways, such as plotting time-frequency diagrams and power spectra. It provides the programs rficonsole, rfigui, aoqplot, aoquality and more.
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. All operations are performed on the CPU.
GALPROP update for accurate propagation calculation
The GALPROP program (http://galprop.stanford.edu) computes cosmic-ray propagation numerically. To obtain manifestly accurate solutions an explicit method is now available to replace the Crank-Nicolson operator-splitting method. This can be implemented in the public version of GALPROP with the update provided here. Instructions: replace the four files propel.cc, propel_diagnostics, Galdef.cc and Galdef.h and rebuild the executable. Add solution_method and solution_convergence to the galdef parameter file. A test GALDEF file with these parameters is galdef_54_reltest09; the diagnostics document the accuracy of the solution. A full explanation is given in the GALPROP Explanatory Supplement http://www.mpe.mpg.de/~aws/galprop_explanatory_supplement.pdf Thanks to Deepak Khurana for requesting and testing this update. Now replaced by this project: http://sourceforge.net/projects/galprop where further updates can be found.
C++/CUDA/OpenMP based Smoothed Particle Hydrodynamics (SPH) Solver
DualSPHysics is based on the Smoothed Particle Hydrodynamics method and can be downloaded from the official website (www.dual.sphysics.org).

Plot GALPROP output
Plot package for GALPROP https://sourceforge.net/projects/galprop Plots models and data for cosmic-ray spectra, secondary/primary ratios, gamma rays, synchrotron. Includes gamma-ray source population synthesis and corresponding plots. For gamma rays, convolves models with the Fermi-LAT response. This release is to assess interest. It requires many input data files (not included) which will be made available as required. With the data provided cosmic-ray spectra and ratios and source population synthesis will work.
