Entire light spectrum of black hole M87’s jet recorded

In April 2019, scientists – among them astrophysicists from Goethe University Frankfurt –  released the first image of a black hole in the galaxy M87 using the Event Horizon Telescope (EHT). Now, 19 observatories collected light from across the spectrum that is emitted by the particle jet prduced by the supermassive black hole in the center of galaxy M87. This is the largest simultaneous observing campaign ever undertaken on a supermassive black hole with jets. The data 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.

​The vaccination formula: rapid vaccination could avoid lockdown even with rising infection numbers

Despite rising infection numbers, contact restrictions could be avoided if the vaccination rate were fast enough. Professor Claudius Gros from Goethe University Frankfurt and Dr Daniel Gros from the Center for European Policies Studies in Brussels have developed a simple mathematical relation which allows to estimate  the  rate of vaccination necessary to maintain control of the pandemic without a lockdown and while avoiding overwhelming the health system and a spike in death rates. The study has been vetted and is forthcoming in Covid Economics.

​Astronomers Image Magnetic Fields at the Edge of M87’s Black Hole

Scientists of the Event Horizon Telescope (EHT) collaboration – among them astrophysicist Luciano Rezzolla and his team from Goethe University Frankfurt – have revealed today a new view of the massive object at the centre of the M87 galaxy: how it looks in polarised light. This is the first time astronomers have been able to measure polarisation, a signature of magnetic fields, this close to the edge of a black hole. The observations are key to explaining how the M87 galaxy, located 55 million light-years away, is able to launch energetic jets from its core – jets, that are about one million light years large.

Goethe University: New, cutting-edge research projects on trust in conflict, neutron stars and disease mechanisms

Neutron stars are the focus of the cluster project ELEMENTS (speaker Prof. Dr. Rezzolla). Neutron stars are the relics of enormous stellar explosions (supernovae) and among the most extreme objects in the Universe: Matter in their core is so densely compressed that, according to calculations, it could even exist in the form of a quark-gluon plasma – a mixture in which matter is broken up into its most elementary particles, as it was in the Universe soon after the Big Bang. Neutron stars – like black holes – cause space-time distortions, and when two neutron stars merge, they produce heavy chemical elements and gravitational waves that can be measured on Earth. In terms of research strategy, ELEMENTS is a continuation of the close collaboration between Goethe University and the Technical University of Darmstadt in the framework of the Rhine-Main Universities alliance. ELEMENTS will receive €7.9 million from the Federal State of Hessen and €8 million as the own contribution of Goethe University and the co-applicants.

​ 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.

CERN-Detektor als Legomodell nachbauen – Einladung an Schüler:innen und Studierende

Das deutsche Netzwerk der ALICE-Kollaboration am CERN lädt Jugendliche ab 16 Jahren und Studierende der ersten Semester ein, den Teilchendetektor ALICE mit Lego nachzubauen. Physiker:innen der Goethe-Universität Frankfurt und der Westfälischen Wilhelms-Universität Münster begleiten das Projekt. Vom 18. Januar an entwerfen die Teilnehmer:innen zunächst das Modell mit Konstruktionsprogrammen, im Juni soll der Lego-Detektor voraussichtlich in Frankfurt zusammengebaut werden. Mitmachen können junge Interessierte aus dem ganzen Bundesgebiet, da die Veranstaltungen online angeboten werden.
