Interactive 3D Visualization for Theoretical Virtual Observatories
Tim Dykes, Amr Hassan, Claudio Gheller +2
Virtual Observatories (VOs) are online hubs of scientific knowledge. They encompass a collection of platforms dedicated to the storage and dissemination of astronomical data, from…
Real-time colouring and filtering with graphics shaders
Dany Vohl, Christopher J. Fluke, David G. Barnes +1
Despite the popularity of the Graphics Processing Unit (GPU) for general purpose computing, one should not forget about the practicality of the GPU for fast scientific visualisatio…
Sports stars: analyzing the performance of astronomers at visualization-based discovery
C. J. Fluke, L. Parrington, S. Hegarty +4
In this data-rich era of astronomy, there is a growing reliance on automated techniques to discover new knowledge. The role of the astronomer may change from being a discoverer to…
Collaborative visual analytics of radio surveys in the Big Data era
Dany Vohl, Christopher J. Fluke, Amr H. Hassan +2
Radio survey datasets comprise an increasing number of individual observations stored as sets of multidimensional data. In large survey projects, astronomers commonly face limitati…
An interactive, comparative and quantitative 3D visualization system for large-scale spectral-cube surveys using CAVE2
Dany Vohl, Christopher J. Fluke, Amr H. Hassan +1
As the quantity and resolution of spectral-cubes from optical/infrared and radio surveys increase, desktop-based visualization and analysis solutions must adapt and evolve. Novel i…
Large-scale comparative visualisation of sets of multidimensional data
Dany Vohl, David G. Barnes, Christopher J. Fluke +8
We present encube a qualitative, quantitative and comparative visualisation and analysis system, with application to high-resolution, immersive three-dimensional environments a…
The Theoretical Astrophysical Observatory: Cloud-Based Mock Galaxy Catalogues
Maksym Bernyk, Darren J. Croton, Chiara Tonini +7
We introduce the Theoretical Astrophysical Observatory (TAO), an online virtual laboratory that houses mock observations of galaxy survey data. Such mocks have become an integral p…
Tera-scale Astronomical Data Analysis and Visualization
A. H. Hassan, C. J. Fluke, D. G. Barnes +1
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. Usi…
A Distributed GPU-based Framework for real-time 3D Volume Rendering of Large Astronomical Data Cubes
A. H. Hassan, C. J. Fluke, D. G. Barnes
We present a framework to interactively volume-render three-dimensional data cubes using distributed ray-casting and volume bricking over a cluster of workstations powered by one o…
Unleashing the Power of Distributed CPU/GPU Architectures: Massive Astronomical Data Analysis and Visualization case study
A. H. Hassan, C. J. Fluke, D. G. Barnes
Upcoming and future astronomy research facilities will systematically generate terabyte-sized data sets moving astronomy into the Petascale data era. While such facilities will pro…
Scientific Visualization in Astronomy: Towards the Petascale Astronomy Era
Amr Hassan, Christopher J. Fluke
Astronomy is entering a new era of discovery, coincident with the establishment of new facilities for observation and simulation that will routinely generate petabytes of data. Whi…
Visualisation and Analysis Challenges for WALLABY
Christopher J. Fluke, David G. Barnes, Amr H. Hassan
Visualisation and analysis of terabyte-scale datacubes, as will be produced with the Australian Square Kilometre Array Pathfinder (ASKAP), will pose challenges for existing astrono…
Astrophysical Supercomputing with GPUs: Critical Decisions for Early Adopters
Christopher J. Fluke, David G. Barnes, Benjamin R. Barsdell +1
General purpose computing on graphics processing units (GPGPU) is dramatically changing the landscape of high performance computing in astronomy. In this paper, we identify and inv…
Interactive Visualization of the Largest Radioastronomy Cubes
A. H. Hassan, C. J. Fluke, D. G. Barnes
3D visualization is an important data analysis and knowledge discovery tool, however, interactive visualization of large 3D astronomical datasets poses a challenge for many existin…
GPU-Based Volume Rendering of Noisy Multi-Spectral Astronomical Data
Amr H. Hassan, Christopher J. Fluke, David G. Barnes
Traditional analysis techniques may not be sufficient for astronomers to make the best use of the data sets that current and future instruments, such as the Square Kilometre Array…
