Visualizing Astronomical Data with Blender

Astronomical data take on a multitude of forms – catalogs, data cubes, images, and simulations. The availability of software for rendering high-quality three-dimensional graphics lends itself to the paradigm of exploring the incredible parameter space afforded by the astronomical sciences. The software program Blender gives astronomers a useful tool for displaying data in a manner used by three...

Tera-scale Astronomical Data Analysis and Visualization

We present a high-performance, graphics processing unit (GPU)-based framework for the efficient analysis and visualization of (nearly) terabyte (TB)-sized 3-dimensional images. Using a cluster of 96 GPUs, we demonstrate for a 0.5 TB image: (1) volume rendering using an arbitrary transfer function at 7–10 frames per second; (2) computation of basic global image statistics such as the mean intens...

A safe data analysis environment for astronomical data centres

The volume of data available to astronomers via the Internet is doubling every twelve months or so. This is due both to the increase in the number of data sources (astronomy is an active field, while archives of old observations retain scientific value) and in the size of individual data sources (multi-TB datasets are the norm in the current generation of sky surveys). The new sky surveys are g...
