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.

Colloquium: Of Bubbles, Filaments, Echoes and Eruptions: First Results from eROSITA on SRG

© CC-BY-SA-NC

The next generation of wide-area, sensitive X-ray surveys designed to map the hot and energetic Universe has arrived, thanks to eROSITA (extended ROentgen Survey with an Imaging Telescope Array), the core instrument on the Russian-German Spektrum-Roentgen-Gamma (SRG) mission.

eROSITA high sensitivity, large field of view, high spatial resolution and survey efficiency is bound to revolutionize X-ray astronomy and deliver large legacy samples for many classes of astronomical objects in the energy range 0.2-8 keV.

I will present an overview of the instrument capabilities, the current status of the mission, a few selected early science results and the expectations for the survey program, which has completed last December the second of its eight planned charts of the whole sky.
