Volcanic ‘activity’ in black holes blows monumental bubbles spanning hundreds of thousands of light years

An international team of researchers, which included astronomers from the Netherlands Institutes for Radio Astronomy (ASTRON) and Space Research (SRON) as well as Leiden University, observed the full extent of the evolution of hot gas produced by an active black hole for the first time.

Inheemse blik op de hemel in Leiden tentoongesteld

Op zaterdag 16 oktober opent de bijzondere tentoonstelling Onder onze hemel (origineel Shared Sky), een culturele blik op de sterrenhemel door Aboriginal Australische en Zuid-Afrikaanse artiesten, in de Oude Sterrewacht in Leiden.

Aurorae discovered on distant stars suggest hidden planets

Using the world’s most powerful radio telescope, LOFAR, scientists have discovered stars unexpectedly blasting out radio waves, possibly indicating the existence of hidden planets.

Periodic Fast Radio Burst found bare, unobscured by strong binary wind

By connecting two of the biggest radio telescopes in the world, astronomers have discovered that a simple binary wind cannot cause the puzzling periodicity of a Fast Radio Burst after all.

Most detailed-ever images of galaxies revealed using LOFAR

After almost a decade of work, an international team of astronomers has published the most detailed images yet seen of galaxies beyond our own, revealing their inner workings in unprecedented detail.

Vidi grant awarded to astronomer Harish Vedantham

Celebrating 'Darkrai', the LOFAR2.0 test subrack

LOFAR2.0 is the future system and will largely replace the current LOFAR system. In the LOFAR2.0 Station project we intend to create an updated station with more robustness against RFI and other strong signals, better performance and updated monitor and control software. This can only be achieved by a new system with many newly designed electronic components.

To meet the challenging requirements of LOFAR2.0, we have designed a completely new LOFAR subrack. And for the first time, we have now been able to integrate nearly all developed components and boards into a first functioning prototype subrack. The subrack contains the qualification models of all the new board designs for LOFAR2, among which the new Uniboard2C, the new RCU2 receivers for the low-band antenna, a new power distribution board and clock and control board. This test setup is called DTS-Lab-Lite, and nicknamed 'Darkrai' in the project; DTS is short for "Dwingeloo Test Station".

Our 'Darkrai' system does not have all the functionality of a full subrack. But it allows us to start measuring the efficiency of the cooling within the subrack, to further develop control and monitor functionality on nearly finished hardware and to set up a first (limited) signal chain. It is therefore a major step forward for the project and the team, and that achievement in itself is worthy of a celebration! On Tuesday, October 19th, we invited the team and the stakeholders to visit 'Darkrai' in the digital lab, and enjoy a piece of cake with each other. Especially the latter was nice, considering that we have not been able to do that in the last year and a half due to COVID restrictions. Gijs Schoonderbeek gave a wonderful tour of 'Darkrai' and left many people impressed by what has been built so far.

Congratulations to our head of Astronomy & Operations @MarkBentum for the best Bachelor Teacher Award 2021 @TUeindhoven! 🥳

We have developed technology that #Neways integrates into complex boards, which it manufactures for ASTRON. This way, we help each other forward.
