Today in ApJL: EHT collaboration published new results

The Event Horizon Telescope (EHT) collaboration has published new results that describe for the first time how light from the edge of the supermassive black hole M87* spirals as it escapes the black hole’s intense gravity, a signature known as circular polarization. The way light’s electric field prefers to rotate clockwise or counterclockwise as it travels carries information about the magnetic field and types of high-energy particles around the black hole. The new paper, published today in Astrophysical Journal Letters, supports earlier findings from the EHT that the magnetic field near the M87* black hole is strong enough to occasionally stop the black hole from swallowing up nearby matter.

New in Nature Astronomy: Space interferometry reveals helical filaments within a supermassive black hole's jet

The Institute of Astrophysics of Andalusia (IAA-CSIC) leads the observation at the highest angular resolution and sensitivity of the jet emerging from the core of the galaxy 3C 279 at nearly the speed of light. The image obtained reveals large helical filaments close to the central engine, the existence of which requires an alternative model to the one employed for four decades to explain the variability of these jets

Science features new paper with co-author Shivani Bhandari, researcher at ASTRON and JIVE


This artist’s impression (not to scale) illustrates the path of the fast radio burst FRB 20220610A, from the distant galaxy where it originated all the way to Earth, in one of the Milky Way’s spiral arms. The source galaxy of FRB 20220610A, pinned down thanks to ESO’s Very Large Telescope, appears to be located within a small group of interacting galaxies.

The "20 MAGIC years" conference (4-7 Oct) and the enigmatic Fast Radio Bursts

A peek inside the conference "20 MAGIC Years" in La Palma, Spain (4-7 Oct). JIVE support scientist, Benito Marcote, gave an insightful talk on Fast Radio Bursts and the successful synergy of the European VLBI Network (EVN) and the MAGIC telescopes in unveiling the regions where they occur.
