IDIA Highlights Brochure – June 2021

We have put together a short IDIA Highlights Brochure for June 2021. IDIA activities are multiple and diverse. In this brochure, we highlight just a few of them, in view of a more substantial activity report later in the year. In the meantime, grab yours here, and feel free to contact us at communications@idia.ac.za for …

CARTA v2.0 released

The CARTA development team is excited to announce that CARTA v2.0 is released today! The development team has tried hard to elevate CARTA to a higher level over the last six months by adding important new features. In addition to the feature development, we also spent a significant amount of time refactoring the codebase so …

New paper: The Global Magneto-Ionic Medium Survey: A Faraday Depth Survey of the Northern Sky Covering 1280-1750 MHz

The Galactic interstellar medium hosts a significant magnetic field, which can be probed through the synchrotron emission produced from its interaction with relativistic electrons. Linearly polarized synchrotron emission is generated throughout the Galaxy, and at longer wavelengths, modified along nearly every path by Faraday rotation in the intervening magneto-ionic medium. Full characterization of the polarized …

New paper: HELP: The Herschel Extragalactic Legacy Project

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 …

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 …

Cosmic beasts and where to find them

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 …
