Famous fast radio burst FRB20180916B just barely lets itself be captured

Two international teams of astronomers (with significant Dutch involvement) have published two scientific papers with new information about the famous fast radio burst FRB20180916B.

Ultra-sensitive radio images reveal thousands of star-forming galaxies in early Universe

An international team of astronomers has published the most sensitive images of the Universe ever taken at low radio frequencies, using the International Low Frequency Array (LOFAR).

Europe’s radio and optical astronomy communities team up in new EC-funded project

A new project has kicked off to enhance cooperation between European astronomy facilities and promote transnational access among them. ASTRON (Netherlands Institute for Radio Astronomy), ILT (International LOFAR Telescope), JIV-ERIC (Joint Institute for VLBI ERIC), and NOVA (Netherlands Research School for Astronomy) are partners based in the Netherlands.

A starry sky made of more than 25,000 supermassive black holes

An international team of astronomers has produced the largest and sharpest map of the sky at ultra-low radio frequencies, using the Low Frequency Array (LOFAR) radio telescope. The map published in the journal Astronomy & Astrophysics reveals more than 25,000 active supermassive black holes in distant galaxies.

People of ASTRON: Paula Fusiara

In People of ASTRON we share stories about the people at ASTRON. Who are the people behind the discoveries and innovations and also, who are the people that make sure that everything runs smoothly? Design engineer Paula Fusiara has been working at ASTRON since 2016.

In Memoriam: Tony Foley (1957 - 2021)

This week our long-time colleague Tony Foley died in Wales, surrounded by his family. He had been suffering from cancer for some time. After a thorough education in Cambridge and Manchester, he worked from 1985 as a WSRT System Scientist, with special responsibility for VLBI. In 2009, he was lured away to South Africa, to take the lead in commissioning the new MeerKat radio telescope.

Arnold van Ardenne: "Tony's early VLBI engagement in Westerbork was crucial in shifting from observing "experiments" towards regular high-quality scheduled observations. His kind and patient personality certainly engendered the spirit required for such instrumentally and socially complex observations".

Albert Jan Boonstra: "I remember Tony as a friendly and warm

colleague. During the Westerbork Upgrade in the 1990s, he was one of the people responsible for keeping the telescope operational while colleagues regularly hampered operations by replacing bits and pieces with new stuff. Tony always kept a positive spirit, and I particularly enjoyed the characteristic wide range of his voice when he expressed his views."

Mark Bentum: "Ik herinner mij Tony ook als een zeer vriendelijke collega, met een groot verantwoordelijkheids gevoel voor de WSRT. Altijd in de weer om het beste uit het instrument te halen, of het nu voor pulsar waarnemingen was, of voor VLBI, of die keer dat we voor de NASA een poging deden om de Mars Polar Lander te detecteren. Een waar gemis".

Zsolt Paragi: Here is a picture of Tony you may like, because it emphasizes the quality for which he is most fondly remembered. Needless to say that he is sorely missed, at multiple latitudes.
