Obituary for Prof. Jesús Gómez González, Pioneer of Spanish Radio Astronomy

09/01/2024

With great sadness, we mourn the loss of Prof. Jesús Gómez González, a founding figure of Spanish radio astronomy.

"Prof. Gómez-González had the vision to create a group of skilled astronomers and engineers in Yebes, who would conduct first-class research and instrumentation in radio astronomy. Today the infrastructures at Yebes, telescopes and laboratories, have well achieved that vision, being also partners in VLBI networks such as the EVN/JIVE, GMVA and IVS", says Francisco Colomer, former director of JIVE ERIC, who worked with him for almost 20 years.

A computer simulation of a disk of plasma around the supermassive black hole at the center of the M87 galaxy. A new analysis of the circularly polarized, or spiraling light, in EHT observations shows that magnetic fields near the black hole are strong. These magnetic fields push back on infalling matter and help launch jets of matter at velocities near the speed of light out. Image credit: George Wong

Today in ApJL: EHT collaboration published new results

08/11/2023
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

26/10/2023
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
