Black holes have been described by Einsten's Theory of General Relativity already more than 100 years ago. In the late 60-ties astronomers discovered that real black holes could exist in the center of galaxies, including our own Galaxy. After many years of observations and research on black holes, in 2017 an Event Horizon Telescope has been constructed out of existing sub-millimeter telescopes to form an Earth size virtual observatory capable of resolving black hole shadow in the center of the our galaxy and in the center of galaxy M87. On April 10, 2019 we presented the first results from EHT, the first images of plasma emission produced near event horizon shadow around supermassvie in M87 galaxy (one of the images is shown above, image credit: EHT Collaboration.).

Polarimetric images of black holes

The first ever photograph of the black hole shadow in the very center of M87 galaxy was published in April 2019 by the Event Horizon Telescope. This figure shows the polarized image of M87 black hole, published on March 24, 2021.

As a member of the Event Horizon Telescope Collaboration , I co-lead first efforts to measure polarization of M87 ring. The figure above shows the polarized version of M87 photo. The new results have been published on March 24, 2021 (see official press release).

So far, EHTC has published a lot of its data in addition to the above. Please see my publication list for full overview or EHT press release webpage. I am activly participating in the collaboration managment, EHT data analysis and interpretation.
