 First polarized image of M87.
Our research group is focused on the study of black hole accretion and relativistic jet formation through very long baseline interferometric (VLBI) observations with mm-wave arrays, such as the Event Horizon Telescope (EHT), and orbiting antennas, such as the space VLBI mission RadioAstron. In particular our research group is playing a key role in the scientific exploitation of the Event Horizon Telescope (EHT).
Our group is part of the Instituto de Astrofísica de Andalucía (IAA-CSIC), in Granada, Spain, currently an EHT affiliated institution, one of the most important investigation centers of the country also distinguished with the “Severo Ochoa Center of Excellence Award”. The group is led by Dr. José L. Gómez who is also the Vice Chair of the EHT Science Council and one of the three coordinators of the EHT Imaging Working Group (WG).
Our research group has become one of the most relevant in the EHT, and played a key role in the analysis and imaging of the EHT observations of SgrA*, the supermassive black hole at the center of the Milky Way. The results are published in a special issue of The Astrophysical Journal Letters.
On 18th Jan 2024, the Event Horizon Telescope Collaboration, including members of our group, released new images of M87*, the supermassive black hole at the center of the galaxy Messier 87, using data from observations taken in April 2018. The paper published in Astronomy & Astrophysics presents new images from the 2018 data that reveal a familiar ring the same size as the one observed in 2017. This bright ring surrounds a deep central depression, “the shadow of the black hole,” as predicted by general relativity. Excitingly, the brightness peak of the ring has shifted by about 30° compared to the images from 2017, which is consistent with our theoretical understanding of variability from turbulent material around black holes.
20+ institutional press releases, 50+ newpapers and magazines in 10+ different languagues, and 100+ social media posts to cover the outreach of this result from the EHT. Members of our group were featured in all the media coverage for this publication.
