External Tool Collection
On this page we collect relevant contributions from the German astronomical community that can be considered VO-like. This includes links to archives with data for download, links to websites delivering services that may be of interest, or links to software for download. We will include international sites which we think will be of interest to the German community as well.We have only just started compiling this collection and we invite developers to provide us with short descriptions and links to their products. Please send mail to webmaster at g-vo.org if you like to have your contribution added here as well. Also suggestions for links to particular sites are welcome.
Archives & catalogues
- ROSAT archives at MPE
- Catalogues at the Hamburger Sternwarte
- Sloan Digital Sky Survey (SDSS) European mirror site at MPA
- 2MASS archive at IPAC
- MPA simulation archives
Services
-
VizieR
Catalogue query service at Centre de Donnees astronomiques de Strasbourg (CDS) - SkyQuery.net
SkyQuery is a prototype of a federated database application, implemented using a set of interoperating Web services. This is a good demo of how typical applications in the Virtual Observatory will look like.
Software Tools
- VO tools
-
Aladin
"Aladin is an interactive software sky atlas allowing the user to visualize digitized images of any part of the sky, to superimpose entries from astronomical catalogs ..." -
VOPlot
"VOPlot is a tool for visualizing astronomical data. VOPlot is developed in JAVA, and acts on data available in the VOTable format. VOPlot is available as a stand alone version, which is to be installed on the user's machine, or as a web-based version fully integrated with the VizieR database." -
TOPCAT
"TOPCAT is an interactive graphical viewer and editor for tabular data. It has been designed for use with astronomical tables such as object catalogues, but is not restricted to astronomical applications. It understands a number of different astronomically important formats (including FITS and VOTable) and more formats can be added." -
Specview
"Specview is a Java application for 1-D spectral visualization and analysis of astronomical spectrograms." -
Mirage
"Mirage is a Java-based software tool for exploratory analysis and visualization of images and multi-dimensional numerical data from an arbitrary domain of study."

- GADGET: GAlaxies with Dark matter and Gas intEracT
- Cactus:
Cactus is an open source problem solving environment designed for scientists and engineers. Its modular structure easily enables parallel computation across different architectures and collaborative code development between different groups. Cactus originated in the academic research community, where it was developed and used over many years by a large international collaboration of physicists and computational scientists. - NIRVANA: numerical tool for astrophysical fluid dynamics
NIRVANA is a robust numerical code for non-relativistic, compressible, time-dependent magnetohydrodynamics in two or three space dimensions on Cartesian grids. NIRVANA applies adaptive mesh refinement (AMR) techniques to handle multi-scale problems and implements a Poisson solver to deal with self-gravitational flows. the non-ideal effects of viscosity, magnetic diffusion, thermal conduction are included in a time-explicit fashion.
