AstroFlash project to localise FRBs

The AstroFlash project will use the European VLBI Network to precisely localise the positions of Fast Radio Bursts.

The cosmic cow explained - radio signals point to an explosion and a newborn magnetar

Observations using 21 telescopes of the European VLBI Network (EVN) have revealed that a cosmic explosion, called AT2018cow most likely formed a neutron star with an extremely powerful magnetic field - known as a magnetar.

Celebrating milestones in space-borne high-resolution radio astronomy

The past decade has seen leaps forward in both the scientific and technical expertise needed to conduct high resolution radio astronomy observations from space. Future detailed studies of compact celestial radio sources, related technologies and recent breakthroughs in the field are highlighted in a special issue of Advances in Space Research, entitled “High Resolution Space-Bourne Radio Astronomy”.

Observing the most distant, yet powerful, engines of the Universe helps astronomers to understand its early formation

Radio astronomers have used a technique known as Very Long Baseline Interferometry (VLBI) to produce high resolution images of the most distant known blazar. The findings, reported in Nature Communications, cover the motion and emission of a jet originating from the heart of the blazar, to provide insights on how galaxies evolve.

A repeating Fast Radio Burst from a spiral galaxy deepens the mystery of where these signals originate from

Telescopes in the European VLBI Network (EVN) have observed a repeating Fast Radio Burst (FRB) in a spiral galaxy similar to our own. This FRB is the closest to Earth ever localised and was found in a radically different environment to previous studies. The discovery, once again, changes researchers’ assumptions on the origins of these mysterious extragalactic events.

Imaging a water maser superburst

In September 2017, during the IAU Symposium 336 "Astrophysical masers: Unlocking the mysteries of the Universe", reports surfaced of two water maser sources going "superburst". Maser Monitoring Organisation (M2O), a team of astronomers led by Ross Burns (a JIVE support scientist at the time), conducted a rapid follow up study to image the superburst in detail. Their findings clarify that the observed superburst was the result of a rare spatial alignment of two maser cloudlets.

Training the next generation of support scientists

The second edition of the ASTRON/JIVE “Traineeship in Science Operations with Massive Arrays” will soon be completed on 26 July 2019. The goal of the traineeship, which is sponsored by ASTRON and the JUMPING JIVE project, is to instruct young researchers in the operation of massive arrays as a preparation for next-generation astronomy facilities like the SKA. The course is 12 weeks long, of which the trainees spend one week at JIVE.

Astronomers observe the ‘smoking gun’ of an orphan gamma-ray burst afterglow

Astronomers have found the ‘smoking gun’ of an ‘orphan’ gamma-ray burst afterglow. Gamma-ray bursts are brief, intense flashes of gamma-rays that are difficult to detect. They are believed to be linked to cataclysmic events such as the collapse of a massive star, or the collision and merger of two neutron stars. Evidence of an ‘orphan’ gamma-ray burst afterglow provides astronomers with more possibilities to study, and ultimately understand, such phenomena.
