First polarized image of the black hole at the centre of the M87 galaxy.  First image of Sagittarius A* the black hole at the centre of our galaxy Milky way.
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”.
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 SgrA* image is a long-anticipated look at the massive object that sits at the very centre of our galaxy. Scientists had previously seen stars orbiting around something invisible, compact, and very massive at the centre of the Milky Way. This strongly suggested that this object — known as Sagittarius A* (Sgr A*, pronounced “sadge-ay-star”) — is a black hole, and today’s image provides the first direct visual evidence of it. The results are published in a special issue of The Astrophysical Journal Letters.
