In an issue packed with retrospectives and news from UWC’s 60th Anniversary year in 2020, IDIA’s language project with the UWC Xhosa department to translate Astronomy resources into isiXhosa get an honourable mention. We also congratulate our Senior research Prof. Mario Santos for his NRF A-rating, a great achievement. Finally, there is also mention of our colleagues from Bioinformatics, and … Read More
The Herschel Extragalactic Legacy Project (HELP) collates, curates, homogenises, and creates derived data products for most of the premium multi-wavelength extragalactic data sets. This is not an easy task, as each telescope used to collect data uses different resolutions, different types of light – wavelengths – and observes different types of objects. Some are point-like sources of light, others are … Read More
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 their search using various observational … Read More
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 signals in higher spatial and … Read More
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 and interact with features in … Read More
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 visible in radio wavelengths. Those … Read More
Gigantic galaxies discovered with the MeerKAT telescope. Cover image: The two giant radio galaxies found with the MeerKAT telescope. In the background is the sky as seen in optical light. Overlaid in red is the radio light from the enormous radio galaxies, as seen by MeerKAT. Left: MGTC J095959.63+024608.6. Right: MGTC J100016.84+015133.0. Credit: I. Heywood (Oxford/Rhodes/SARAO).
