Telescope quartet reveals surprising statistics of cosmic flashes

Scientists led by Chalmers astronomer Franz Kirsten have studied a famous source of repeating fast radio bursts – a still unexplained cosmic phenomenon. Comparing with earlier measurements, the scientists draw a conclusion with far-reaching consequences: any source of fast radio bursts will repeat, if watched long enough and carefully enough. The research team, a unique collaboration between professional and amateur radio astronomers, used four telescopes in northern Europe, amongst which ASTRON’s Westerbork Synthesis Radio Telescope.

Pulsar clocks open new window on gravitational waves

An international collaboration of European astronomers, together with Indian and Japanese colleagues, have seen evidence for ultra-low-frequency gravitational waves, which is expected to originate from pairs of supermassive black holes found in the centres of merging galaxies. This is the result of more than 25 years of observations with the most sensitive radio telescopes in Europe and India, including the Westerbork Synthesis Radio Telescope (WSRT). In doing so, they have opened a new window on gravitational wave research. These gravitational waves contain information about the Universe’s best-kept secrets. The research has been published in a series of articles in the professional journal Astronomy & Astrophysics.

Astronomers discover Fast Radio Bursts that skewer nearby Galaxy

Astronomers have found five new Fast Radio Bursts with the upgraded Westerbork radio telescope array. The telescope images revealed that multiple bursts had pierced our neighbouring Triangulum Galaxy. This allowed the astronomers to determine the maximum number of otherwise invisible atoms in this galaxy for the first time.

Westerbork and the future of GigaHertz astronomy

The Westerbork Synthesis Radio Telescope (WSRT) has been a powerhouse of science since it began operations in 1968, making more than 50 years of discoveries in radio astronomy happen. Looking forward, we will strengthen our activities in Westerbork on VLBI, GNSS, data releases of the Apertif surveys, and developing next-generation technology for our instruments.

Periodic Fast Radio Burst found bare, unobscured by strong binary wind

By connecting two of the biggest radio telescopes in the world, astronomers have discovered that a simple binary wind cannot cause the puzzling periodicity of a Fast Radio Burst after all.
