Simultaneous optical and radio observations of Perseids

From today (August 11th) up until Friday the yearly Perseids meteor shower will have its peak. This phenomenon is not only interesting for amateur astronomers, professional astronomers will be observing them as well.

Humans of ASTRON: Jorrit Siebenga

In Humans 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? In this second part of the series, we’ll be sharing the story of Jorrit Siebenga, who joined ASTRON in 2017 as research instrument maker.

Women Astronomers Day

Throughout the history of astronomy, women have played essential roles towards astronomical breakthroughs. In this article we highlight but a few of these women identified in history from 1600 to the modern era.

NAC 2026 3rd poster prize for Dirk Kuiper, Sylvain Ranguin & Lars Zwaan

One of the traditions at the annual Nederlandse Astronomen Conferentie (NAC; Netherlands Astronomy Conference) is the poster competition. This year, University of Amsterdam & ASTRON PhD candidates Dirk Kuiper, Sylvain Ranguin and Lars Zwaan won 3rd prize for their combined poster "EuroFlash: A 24/7 commensal search machine for (not-so) fast radio transients". The prize committee emphasised both the scientific quality of the work and the creative approach of combining three poster submissions in one mega-poster, which underlines the importance of collaboration and teamwork in science.

Dirk, Sylvain, and Lars are advised by Cees Bassa, Jason Hessels, Ziggy Pleunis, and Antonia Rowlinson at UvA/ASTRON, and they're working closely with ASTRON postdocs Reshma Anna-Thomas and Inés Pastor-Marazuela on LOFAR transient searches. With the new EuroFlash system on LOFAR2.0 we will be able to perform these searches in real-time, which enables rapid multi-wavelength follow-up to understand the astrophysics of newly discovered sources.
