Instituto Galego de Física de Altas Enerxías (Igfae), de la Universidade de Santiago de Compostela (USC), participa en la primera detección de dos raros eventos hasta ahora nunca observados, ocurridos en apenas 10 días de diferencia en enero de 2020: la colisión entre un
agujero negro y una estrella de neutrones.

This illustration provided by Carl Knox depicts a black hole, center, swallowing a neutron star, upper left. The blue lines are gravitational waves, ripples in time and space, which is how astronomers detected the merger, and orange and red areas indicate parts of the neutron star being stripped away. In a report released on Tuesday, June 29, 2021, astronomers say they have witnessed a black hole swallowing a neutron star, the most dense object in the universe, all in a split-second gulp.
HANFORD, Wash. Stargazers have observed space above us for centuries, but never before have scientists confirmed a collision between a black hole and a neutron star. That changed recently when the Laser Interferometer Gravitational-Wave Observatory (LIGO) in Hanford and its twin observatory in Livingston, Louisiana detected two of these instances in January 2020.

While Sukanya Chakrabarti, an Indian origin researcher has pointed out the best places to host big black hole merging at the edges of spiral galaxies like Milky Way, another group of researchers from Australian National University (ANU) and Swinburne University of Technology has discovered the most ancient spiral galaxy in the universe.

EHT Collaboration
Cambridge, MA – In April 2019, scientists released the first image of a black hole in galaxy M87 using the Event Horizon Telescope (EHT). However, that remarkable achievement was just the beginning of the science story to be told.
Data from 19 observatories released today promise to give unparalleled insight into this black hole and the system it powers, and to improve tests of Einstein’s General Theory of Relativity.
“We knew that the first direct image of a black hole would be groundbreaking,” says Kazuhiro Hada of the National Astronomical Observatory of Japan, a co-author of a new study published in The Astrophysical Journal Letters that describes the large set of data. “But to get the most out of this remarkable image, we need to know everything we can about the black hole’s behavior at that time by observing over the entire electromagnetic spectrum.”
