ALMA Science Archive remote visualization with CARTA

The Atacama Large Millimeter/submillimeter Array (ALMA) is a large interferometer radio telescope in Chile, one of the largest astronomy projects in existence, at least until the Square Kilometre Array is built. The ALMA Science Archive (ASA) contains the public and proprietary data of all ALMA observations. Through the Archive Query Interface, the user can constrain …

CARTA – A New Astronomy Visualization Tool

The advent of very large telescopes, and their increasingly complex and voluminous data products, means digital astronomical data now needs special treatment to be understood. Simple two-dimensional graphs can no longer adequately portray the massive amounts of data pouring in from huge radio interferometers like ALMA, ASKAP, LOFAR, MeerKAT and soon the SKA, which perceive …

Virtual Reality and Immersive Collaborative Environments: the New Frontier for Big Data Visualisation

The IDIA Vislab team has published a paper on their immersive visualisation work. They describe a software package they are busy developing: The iDaVIE software suite currently under development reads from both “volumetric data cubes” and “sparse multi-dimensional catalogs”, rendering them in a room-scale immersive environment that allows the user to intuitively view, navigate around …

New paper on machine learning to characterise radio galaxies

Classification of radio galaxies is looking at their shape, their morphology. Studying the shapes of galaxies in one thing we use to learn more about the formation and evolution of those great megacities of hundreds of billions stars, black holes and other cosmic beasts. Radio galaxies are galaxies that have very interesting features that are …

IDIA Senior Researcher Wins Exceptional Young Researchers Award

For the first time in the institution’s history, the University of Pretoria (UP) held its annual Academic Achievers’ Awards virtually. By no means, however, was the significance of this prestigious event dampened by what Vice-Chancellor and Principal Professor Tawana Kupe deems to have been “extraordinary circumstances”. “We have been celebrating UP’s academic achievers for more …

MIGHTEE-HI: The HI emission project of the MeerKAT MIGHTEE survey

In this new paper, the observations of neutral hydrogen in the MIGHTEE survey conducted on the MeerKAT telescope are described. This particular project addresses 10 science questions, which shows the breadth of science that can be carried out thanks to the unique ability of MeerKAT to observe faint neutral hydrogen signals. Neutral Hydrogen, called HI …
