IDIA - Inter-University Institute for Data Intensive Astronomy

What IDIA - Inter-University Institute for Data Intensive Astronomy does

IDIA (Inter-University Institute for Data Intensive Astronomy) is a Cape Town-based, non-profit research consortium established in 2015 as a partnership between the University of the Western Cape, the University of Cape Town, and the University of Pretoria, operating in close collaboration with the South African Radio Astronomy Observatory (SARAO). The institute's mandate is to build and operate the data, software, and skills infrastructure required to extract science from MeerKAT and the Square Kilometre Array (SKA). IDIA runs the ilifu Research Cloud (14PB storage, 4000+ processor cores, 99% uptime) and co-develops two internationally adopted visualisation tools: CARTA, a cube rendering and analysis tool built with ASIAA, NRAO and AusSRC, and iDaVIE, a 3D volumetric VR explorer. It also maintains the IDIA Pipeline (processMeerKAT), an automated CASA/MPICASA-based calibration pipeline, and operates the IDIA Visualisation Laboratory at UCT and the Iziko Planetarium.

The institute's "customer base" is academic: 122+ institutions across 32 countries access ilifu, with 600+ active users on its visualisation stack and over 500 postgraduate students supported through training, hackathons, and outreach. IDIA enables more than 25% of MeerKAT-based published papers and supports flagship projects including MIGHTEE, ThunderKAT, superMIGHTEE, MeerLICHT, HIPPO, and the WISE Extended Source Catalogue. Funding flows from the National Research Foundation, the Department of Science and Innovation, SARAO, the three partner universities, and joint fellowship programmes with NRAO, ASIAA, AusSRC, ICRAR, INAF, ASTRON and others; IDIA does not charge end users and has no equity, VC, or public ownership.

IDIA's go-to-market is community-led rather than commercial: access is provisioned through institutional partnerships and MeerKAT project calls, and the institute extends its reach via hackathons, schools (e.g., DARA Big Data Africa), the IDIA quarterly newsletter, social channels, scientific publications, and conferences such as ADASS, IAU meetings, RADIOMAP, and SPARCS. Recent strategic activity includes the CARTA v5.0 release (July 2025), the iDaVIE v1.0 public release (October 2024), BRICS Astronomy Working Group participation on the BITDN flagship, and ilifu federation with the EGI Foundation; the institute also won the NSTF-South32 Special Award (2023/2024) and was named a finalist in 2025/2026 for CARTA.

Direct peers

• International Centre for Radio Astronomy Research (ICRAR): Australian research centre focused on SKA science, data intensive astronomy and engineering. Collaborates with IDIA on CARTA and SKA Regional Centre interface specifications, providing an almost mirror-image peer in the Australian SKA ecosystem.
• Academia Sinica Institute of Astronomy and Astrophysics (ASIAA): Taiwanese institute developing radio astronomy instrumentation, software and data tools. Core partner in the CARTA consortium with IDIA, providing a close peer on visualisation tooling for radio astronomy datasets.
• ASTRON (Netherlands Institute for Radio Astronomy): Operates leading radio astronomy facilities (LOFAR, Westerbork) and develops data/compute infrastructure similar to IDIA's ilifu, with collaboration on software, cloud computing and science data centre work. Highly comparable as a national radio astronomy data infrastructure provider.
• CIRADA (Canadian Initiative for Radio Astronomy Data Analysis): Canadian consortium producing radio astronomy data products and services, including for SKA pathfinders. Collaborates with IDIA on software, infrastructure and visualisation, making it a close functional peer in North America.
• National Radio Astronomy Observatory (NRAO): US national radio astronomy observatory operating VLA, ALMA and the VLBA, with major investments in data processing and visualisation. Direct collaboration with IDIA on CARTA development and joint postdoctoral programmes, making it a tightly coupled peer.
• SKA Observatory (SKAO): The intergovernmental observatory building and operating the Square Kilometre Array, which IDIA's infrastructure directly supports. IDIA is functionally a regional node serving SKA science, making SKAO the most direct counterpart organisation.
• INAF (Istituto Nazionale di Astrofisica): Italian national astrophysics institute operating radio telescopes (e.g. Sardinia Radio Telescope) and developing visualisation (iDaVIE collaboration) and data infrastructure. Comparable as a national-scale radio astronomy data and visualisation peer.
• JIVE (Joint Institute for VLBI ERIC): European institute operating the VLBI global data correlator and providing radio interferometry data products. Collaborates with IDIA on infrastructure and visualisation, and serves a similar scientific community with comparable data-intensive demands.

Others

• EGI Foundation: Federation of research computing and data resources across Europe. Federates IDIA's ilifu resources and supports radio astronomy applications deployment, making it an enabling infrastructure peer rather than direct competitor.

Broad incumbents

• CSIRO (Australia's national science agency, ATNF): Operates the Australia Telescope National Facility including ASKAP and the ATNF data archive. Comparable as a much larger, well-funded national radio astronomy observatory with established data products serving global users.
