Astronomy Award presented to Event Horizon Telescope Collaboration

The Event Horizon Telescope (EHT) collaboration (which includes physicists from Goethe University) is pleased to have been granted by the Royal Astronomical Society (RAS) the 2021 Group Achievement Award (A).  The EHT is a global network of synchronised radio observatories that work in unison to observe radio sources associated with black holes.  In April 2019, the EHT team showed the world the first image of the shadow cast by the black hole in M87, made possible by the enormous baselines which give the EHT its exquisite angular resolution.

The RAS citation statement, made public on January 8th, 2021, reads: “this image has already inspired millions and will continue to do so. It represents an important milestone in human ingenuity and scientific endeavour, and is opening new doorways to study the physics of accretion around super-massive black holes in completely unprecedented ways.”  Furthermore, “the realisation of the EHT represented a formidable challenge and was made possible only by decades of hard work and commitment by thirteen stakeholder institutions, a variety of agencies, and more than three hundred forty researchers. This is one of the finest examples of an achievement resulting from close collaboration by researchers from around the World.”

The members of the EHT are honoured by this distinction that the RAS awards in order to recognize outstanding achievements by large consortia in any branch of astronomy.  Among the previous winners count the Planck Team in 2018 and the LIGO Team in 2017. For its unparalleled precise observations, the EHT combines the power of existing telescopes that can observe at millimetre wavelength around the world, including the ALMA interferometer in the Chilean Andes that is operated in a joint global collaboration.

“What a good way to start the New Year! A very important recognition of the power of teamwork, reminding us all that together we can reach even the hardest goals, just like we are trying to do with this pandemic”, says Prof. Luciano Rezzolla, the leader of the EHT group in Frankfurt and member of the EHT Board.
