Energy loss gives unexpected insights in evolution of quasar jets

An international team of astrophysicists observed for the first time that the jet of a quasar is less powerful on long radio wavelengths than earlier predicted. This discovery gives new insights in the evolution of quasar jets. They made this observation using the international Low Frequency Array (LOFAR) telescope, that produced high resolution radio images of quasar 4C+19.44 located over 5 billion light-years from Earth.Read more

Founding Members sign SKA Observatory treaty

Rome, Italy, Tuesday 12th of March 2019 - Countries involved in the Square Kilometre Array (SKA) Project have come together in Rome for the signature of the international treaty establishing the intergovernmental organisation that will oversee the delivery of the worlds' largest radio telescope.Read more

New sky map detects hundreds of thousands of unknown galaxies

An international team of more than 200 astronomers from 18 countries has published the first phase of a major new radio sky survey at unprecedented sensitivity using the Low Frequency Array (LOFAR) telescope. The survey reveals hundreds of thousands of previously undetected galaxies, shedding new light on many research areas including the physics of black holes and how clusters of galaxies evolve. A special issue of the scientific journal Astronomy & Astrophysics is dedicated to the first twenty-six research papers describing the survey and its first results. Read more

COBALT2.0 sets the stage for a fully multitasking LOFAR

On Monday 11 February, we acquired the new state of the art 'brains' for the Low Frequency Array (LOFAR). We are now the proud owners of the COBALT2.0 GPU cluster. COBALT2.0 will execute the next generation correlator and beam forming application of LOFAR. Bossers & Cnossen supplied the cluster in partnership with Dell Technologies. COBALT2.0 is a state-of-the-art cluster and its design is future proof. COBALT2.0 is amongst the most energy efficient (greenest) HPC correlators. Read more

International Central Signal Processor consortium concludes design work

The international Central Signal Processor (CSP) consortium has concluded its design work on the SKA, marking the end of five years' work comprised of 11 signatory members from 8 countries with more than 10 additional participating organisations.Read more

The Netherlands is going to monitor eruptions on the sun

ASTRON (Netherlands Institute for Radio Astronomy) and S[&]T (Science [&] Technology) are starting the construction of a solar radio telescope that directly detects eruptions on the sun. The reason for the construction is a request from the Ministry of Defense. The KNMI (Royal Netherlands Meteorological Institute) is also participating in this project. The first phase of the project DISTURB (Disturbance detection by Intelligent Solar radio Telescope or (Un)perturbed Radiofrequency Bands) in which the design of the radio telescope is developed started on 30 January.Read more

The Netherlands will partner to build the largest radio telescope in the world

ASTRON, the Netherlands Institute for Radio Astronomy, is excited that the Netherlands will partner in the construction and management of the largest radio telescope in the world, the Square Kilometre Array (SKA). This ambitious project will lead to major discoveries about the nature of our Universe and answer longstanding questions. The Dutch Council of Ministers has decided that the Netherlands will sign the treaty to establish the international SKA observatory. ASTRON coordinates the Dutch participation in the SKA.Read more

ASTRON has new institute advisory board

ASTRON's new Institute Advisory board (“instituutsadviesraad” or IAR) met for the first time on 17 December 2018. This Board, chaired by Jozias van Aartsen, is an important non-scientific panel able to guide ASTRON’s relationships with key national stakeholders. Read more

Proceedings third LOFAR Data Processing School published

As part of their Astrophysics and Space Science Library series, Springer has published the volume 'Low Frequency Astronomy and the LOFAR observatory'. The book is based on material from the Third LOFAR Data Processing School, which took place at ASTRON in November 2014. The school featured nineteen lectures by experts in the field and with LOFAR in particular; five tutorial sessions; two evening lectures; and a tour of the LOFAR core area near Exloo. Fifty participants attended the event. Read more

First Dutch team involved in a moon landing

The Chinese space agency will be launching the Chang’e 4 moon lander on Friday 7 December, hoping to make China the first country to land on the far side of the moon. Dutch astronomers are also looking forward to the launch as they are collaborating with Chinese scientists on this mission. A satellite containing a Dutch radio instrument has already been launched to the far side of the moon, ready to be switched on once the moon lander touches down. Read more
