Projects

ROOT

The ROOT system provides a set of OO frameworks with all the functionality needed to handle and analyse large amounts of data in a very efficient way. Included are histograming methods in 1, 2 and 3 dimensions, curve fitting, function evaluation, minimisation, graphics and visualization classes to ... [More] allow the easy setup of an analysis system that can query and process the data interactively or in batch mode. Thanks to the builtin CINT C++ interpreter the command language, the scripting, or macro, language and the programming language are all C++. ROOT is widely used by researchers in the field of High Energy Physics and has been developed at CERN (www.cern.ch). [Less]

Gravit

Gravit is a gravity simulator which runs under Linux, Windows and Mac OS X. It's released under the GNU General Public License which makes it free. It uses Newtonian physics using the Barnes-Hut N-body algorithm. Although the main goal of Gravit is to be as accurate as possible, it also creates ... [More] beautiful looking gravity patterns. It records the history of each particle so it can animate and display a path of its travels. At any stage you can rotate your view in 3D and zoom in and out. Gravit uses OpenGL with Lua, SDL, SDL_ttf and SDL_image. [Less]

Einstein Toolkit

The Einstein Toolkit Consortium is developing and supporting open software for relativistic astrophysics. Our aim is to provide the core computational tools that can enable new science, broaden our community, facilitate interdisciplinary research and take advantage of emerging petascale computers and advanced cyberinfrastructure.

LORENE

LORENE is a set of C++ classes to solve various problems arising in numerical relativity, and more generally in computational astrophysics. It provides tools to solve partial differential equations by means of multi-domain spectral methods.

aicer

AICer is an IDL program for compounding astronomical images. This is a test program of IDL widget interface. Requires IDL version 6.0 or greater. Requires David Fanning's rd_tfile.pro routine (http://www.dfanning.com/). Requires the GSFC IDL astronomy user's library routines (The IDL ... [More] Astronomy User's Library). Some features may not work under all operating systems. The latest version is 0.2.5. Initially, this program is designed to overlay contour map and starcatalogue on a fits image. Now some new features have been added to it. Update 0.2.6 Image layer: fix a critical error in drawing RGB images. Note: this error may cause unexpected NaN values appearing in some part of the images. Setting: paper size is editable now, format as A4,B5,5*5,10*30,etc are accepted. 0.2.5 Complete the HELP in each window, thought faults in grammar may exist. Image layer: now can specify a color for the NaN values in the fits file. 0.2.4 Shape layer: ellipse and box can be plotted with correct size and angle at different DEC. NOTE: in this version, the size of ellipse has been changed from radius to diameter. 0.2.3 Image layer: nan pixals can be draw as the maximum/minmum color of the fits file Text layer: can use WCS as the position to draw text 0.2.2 New layer - shape layer: can draw shapes on the plot(beamsize, arrow, etc) Image layer: colorbar can be drawn 0.2.1 Contour layer: fix a widget display error in point part of CONTOUR widget Image layer: add scale choice to Pixal Distribution module for IMAGE widget, similar to DS9. A new function to calculate the ZScale value of a image were added, based on the algorithm in IRAF Misc: when there is a program error, display the possible problem [Less]

Astropy is a package intended to contain much of the core functionality and some common tools needed for performing astronomy and astrophysics with Python.

astronomyworks

AstronomyWorks is dedicated to providing reliable software tools to the astronomical community. We work to enhance existing tools and development new ones to support the work of astronomers around the world.

celeste

NOTE: New Download procedureTo facilitate version control, we have started uploading new versions and checking out the latest version with svn. To download the latest version of the code you can type: svn checkout http://celeste.googlecode.com/svn/trunk/celeste celeste from the directory where ... [More] you want the code to be. A new directory will be created from the directory you are in called celeste with the code inside. The old procedure for downloading the code still works. For now svn is experimental. More details in Installation If you use CELESTE3D, we request that you inform us and reference the papers listed belowOur work is done for Science and for the benefit of Humankind (without implying any intention of restricting access to benevolent aliens). So we only require that you give credit explicitly to the code Celeste3D and that you reference the three papers listed below, if you use in any way the codes provided here or the results of them for your publications. We ask also to be notified of any published material using the code (just so that we can reference it). If you require assistance in using the code, than it might become appropriate (and this will depend from case to case) to have a more formal collaboration, including co-authorship of the outcome of the collaboration.

Lapenta, Formulation of the relativistic moment implicit particle-in-cell method, Physics of Plasmas, 14, 042308 (2007) The research on the codes presented here has received funding from the European Community's Seventh Framework Programme (FP7/2007-2013) under the grant agreement n° 218816 (SOTERIA project, www.soteria-space.eu). Description of the code Celeste 3DKinetic plasma simulation typically requires to handle a multiplicity of space and time scales. The implicit moment particle in cell PIC method provides a possible route to address the presence of multiple scales effectively. Here, a new implementation of the implicit moment method is implemented in the code: CELESTE3D code, a fully electromagnetic and fully kinetic PIC code, based on the implicit moment method. The code has been in use for a number of years. A number of input files for different benchmarks of CELESTE3D are included to show the typical application. The Implicit Moment MethodA description of the numerical method in CELESTE3D is available on these published papers: on Journal of Computational Physics An implicit method for electromagnetic plasma simulation in two dimensions by Brackbill and Forslund on Physics of Plasmas Kinetic approach to microscopic-macroscopic coupling in space and laboratory plasmas by Lapenta, Brackbill, Ricci a recent writeup is freely available from arXiv: arXiv paper on the method used in CELESTE3D The Special Relativity Implicit Moment MethodThe implicit moment method has been extended also to plasmas treated with special relativity: K.
