Applied RF technology course
Mon 03 Apr 2023 - Thu 06 Apr 2023
The RF course is an excellent introduction for Digital / Analog engineers who are or will be involved in the development of RF systems.
Jason Hessels, Professor of Observational High-Energy Astrophysics at the University of Amsterdam and Chief Astronomer at ASTRON, has been awarded a €3.5 million ERC Advanced Grant to search for the origin of fast radio bursts. Among other things, the research money will be used to develop new hardware to set up a coordinated network of European radio telescopes to study repeating FRBs in more detail.
We have created an animation, which briefly explains the workings of our LOFAR radio telescope.
The 78th edition of the Nederlandse Astronomen Conferentie (NAC) will be held this year in the Westcord WTC hotel in Leeuwarden from 15 to 17 May.
Recently, the astronomy group within the A&O department of ASTRON went through a reformation: instead of several focus groups, it now consists of two groups: the LOFAR Science Group and the SKA Science Group. The LOFAR Science Group is led by André Offringa, the SKA Science Group by Joe Callingham.

Due to the great interest in solving this puzzle, enormous progress has been made in recent years. There are now hundreds of known FRB sources, dozens of which repeat, and some of which have been localised to their exact galactic neighbourhoods. The FRB sample continues to grow at a rapid pace of several new sources per day, thanks to new wide-field radio telescopes. Studying these sources with dedicated follow-up is challenging because they emit sporadically and are only visible for milliseconds or less. At the same time, by casting an even wider net we are likely to discover new types of FRB-like signals.
With EuroFlash, a recently awarded ERC Advanced grant, I will create a coordinated network of European radio telescopes operating over a broad range of radio frequencies, providing high sensitivity and observing cadence, and achieving the best-possible localisations. I will use this network to perform a world-leading, systematic study of repeating FRBs, to understand their progenitor(s) and their relation to the apparently one-off FRB sources. I will also make a novel exploration of the parameter space of short-duration radio transients by exploiting the large field-of-view of LOFAR2.0 and commensal observations to find new sources. In doing so, I aim to discover new types of astrophysical phenomena that probe the extremes of the Universe.
