Research Interests

Our research group, which includes Drs. Gómez, Zhao, and Lico, as well as PhD student Fuentes, is focused on the study of black hole accretion and relativistic jet formation through very long baseline interferometric observations (VLBI) with mm-wave arrays, such as the Event Horizon Telescope (EHT), orbiting antennas, such as the space VLBI mission RadioAstron, and long-term monitoring programs such as MOJAVE and VLBA-BU-BLAZAR.

The Event Horizon Telescope captures the first image of a black hole shadow

On April 10th 2019 the Event Horizon Telescope (EHT) Collaboration revealed the first image of a black hole. The image (above) shows an asymmetric bright emission ring, which encompasses a central depression in brightness, known as the “shadow” of the black hole, produced by the photon capture within the event horizon of the black hole. Overall, the size, circularity, asymmetry, and brightness contrast of the observed image are consistent with the shadow of a Kerr black hole as predicted by GR and provide one the strongest evidence to date of the existence of supermassive black holes in the nuclei of galaxies. With this image the EHT has opened a completely new window to study gravity, bringing into focus not only the persistent strong-field gravity features predicted by general relativity, but also the fine details of black hole accretion and relativistic jet launching.

The Event Horizon Telescope has been awarded with the 2020 Breakthrough Prize in Fundamental Physics for obtaining “the first image of a supermassive black hole, taken by means of an Earth-sized alliance of telescopes.”
