Green light given for construction of world’s largest radio telescope arrays

At a historic meeting of its Council on 25 June 2021, the SKA Observatory (SKAO) saw its Member States give the green light for construction of the SKA telescopes in Australia and South Africa to commence. We spoke to Michiel van Haarlem, head of the Dutch SKA Office at ASTRON, about what this important milestone means.

ASTRON reveals life cycle of supermassive black hole

In a first time ever, astronomers have combined LOFAR and WSRT-Apertif to measure the life cycle of supermassive black holes emitting radio waves. This study, part of the LOFAR deep fields surveys, opens the possibility of timing this cycle for many objects in the sky and explore the impact it has on galaxy evolution.

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

Using LOFAR, an international team of astronomers has published the most sensitive images of the Universe ever taken at low radio frequencies. By observing the same regions of sky over and over again and combining the data to make a single very-long exposure image, the team has detected the faint radio glow of stars exploding as supernovae, in tens of thousands of galaxies out to the most distant parts of the Universe.

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 LOFAR. The map published in the journal Astronomy & Astrophysics reveals more than 25,000 active supermassive black holes in distant galaxies.
