The Cosmic Savannah

In this special episode of The Cosmic Savannah, we celebrate the 10th anniversary of IDIA(Inter-University Institute for Data Intensive Astronomy) with three very special guests: the new director Professor Roger Deane, astronomy support specialist Walter Silima, and head of outreach and development Associate Professor Sally McFarlane.

In this episode of the Cosmic Savannah, Dan and Francois sit down with Dr Nick Erasmus to discuss the ATLAS digital assistant and the use of Artificial Intelligence and Machine Learning in Astronomy and how this technology is shaping the new astronomy landscape, and what the role of the astronomer will be in this new age.

with Prof Matt Jarvis, Dr Imogen Whittam and Dr Anastasia PonomarevaIn this episode, Jacinta takes us back to Oxford to catch up with researchers leading one of the biggest astronomy projects with South Africa’s MeerKAT radio telescope — the MIGHTEE Survey!We hear from Prof. Matt Jarvis, Dr. Imogen Whittam, and Dr. Anastasia Ponomareva at the University of Oxford, who explain how astronomers use MeerKAT to study how galaxies have changed over the history of the Universe – a process called galaxy evolution. MIGHTEE looks at both the raw gas that fuels new stars (neutral hydrogen, or HI) and the powerful black holes at galaxy centres that can regulate star formation with their giant radio jets. The survey also brings together more than a hundred scientists worldwide and provides unique opportunities for South African students to lead exciting discoveries.The team talk us through how they map hydrogen gas in 3D using the famous 21-cm signal, why puzzling results suggest galaxies have kept the same supply of gas even as their star formation has slowed, and how new data challenges the textbook picture of how black holes are fuelled. They also describe the practical challenges of handling thousands of radio sources and how international collaborations of around 100 astronomers make it all possible.This episode follows on from our last, where Jacinta’s RADHIANCE students shared their Oxford adventures — now we dive into the cutting-edge science itself!

We are back with the second half of season 6!In this episode, we are joined by Kevin Govender, Chair of the National Organising Committee and Director of the Office of Astronomy for Development (OAD). With a background in Nuclear Physics, Kevin first became involved in astronomy in 2006 when he managed the Collateral Benefits Programme at the South African Astronomical Observatory (SAAO). This work ultimately led to his appointment as the inaugural Director of the OAD in 2011.

In this episode of The Cosmic Savannah, hosts Dr. Tshiamiso Makwela, Dr. Jacinta Delhaize, and Dr. Daniel Cunnama speak with Dr. Eli Kasai from the University of Namibia. Dr. Kasai shares his inspiring journey of establishing the astronomy department at the University of Namibia, and his work on blazars using SALT and the Cherenkov Telescope Array. He also discusses the exciting African Millimetre Telescope project and Namibia's active role in the global astrophysics community, along with efforts to engage the public through the mobile planetarium.
