Computing time for simulations...

... for more accurate models of merging double star systems

FIAS Senior Fellow Prof. Luciano Rezzolla will receive 102 million CPU hours next year at the supercomputer superMUC of the Leibniz Computing Center in Garching near Munich, which he will use for the simulation of neutron star double systems at Goethe University Frankfurt.

Surprising network activity in the immature brain: Developing brain networks act locally to build globally

Even before the first eye opening, local circuits can cause global effects

One of the outstanding mysteries of the cerebral cortex is how individual neurons develop the proper synaptic connections to form large-scale, distributed networks. Now, an international team of scientists has gained novel insights from spontaneously generated patterns of activity by local networks in the early developing visual cortex. Apparently these form the basis for long-range neural connections that are established through brain activity over the course of cortical development. The scientists report their findings in the journal Nature Neuroscience.

Elucidating cuttlefish camouflage

Computational image analysis of behaving cuttlefish reveals principles of control and development of a biological invisibility cloak

The unique ability of cuttlefish, squid and octopuses to hide by imitating the colors and texture of their environment has fascinated natural scientists since the time of Aristotle. Uniquely among all animals, these mollusks control their appearance by the direct action of neurons onto expandable pixels, numbered in millions, located in their skin. Scientists at the Max Planck Institute for Brain Research (MPI Brain Research), and the Frankfurt Institute for Advanced Studies (FIAS) and Goethe University (GU) used this neuron-pixel correspondence to peer into the brain of cuttlefish, inferring the putative structure of control networks through analysis of skin pattern dynamics. The scientists report their findings in the journal Nature.

The Logistics of Neuronal Function

Giersch International Symposium brings internationally renowned scientists to Frankfurt

The human brain consists of a highly complex network of about 85 billion nerve cells (neurons) that constantly exchange information. To function, all these cells have to organise the production, transport, storage and recycling of countless different molecules such as neurotransmitters, mRNA and proteins - a gigantic logistical challenge at the molecular level. So how do they organize these processes to be both robust and efficient? How do problems in solving these logistical challenges relate to brain diseases such as Alzheimer's or Parkinson's disease? To discuss these questions, neuroscientists from all over the world will meet from 28 August for the 3rd Giersch International Symposium at the Frankfurt Institute for Advanced Studies (FIAS).

Frankfurt physicists set limits on size of neutron stars

Comparison of theoretical models with gravitational waves results in the answer to an old riddle

How large is a neutron star? Previous estimates varied from eight to sixteen kilometres. Astrophysicists at the Goethe University Frankfurt and the FIAS have now succeeded in determining the size of neutron stars to within 1.5 kilometres by using an elaborate statistical approach supported by data from the measurement of gravitational waves. The researchers’ report appears in the current issue of Physical Review Letters.

The Art of Theoretical Biology

Professor from Frankfurt shows the beauty of theoretical biology

In an exhibition of a different kind, Frankfurt bioinformatician Prof. Franziska Matthäus and the Frankfurt Institute for Advanced Studies (FIAS) show that basic theoretical research does not only consist of series of numbers and formulae, but can also be beautiful. For the "Night of Science" on Friday, June 8. 2018, large-format works of art will decorate some buildings on the Riedberg campus of Goethe University.

Black Holes from an Exacomputer

Scientists develop simulation code for new generation of supercomputers

FRANKFURT. Even after the direct measurement of their gravitational waves, there are still mysteries surrounding black holes. What happens when two black holes merge, or when stars collide with a black hole? This has now been simulated by researchers from Goethe University Frankfurt and the Frankfurt Institute for Advanced Studies (FIAS) using a novel numerical method. The simulation code "ExaHyPE" is designed in such a way that it will be able to calculate gravitational waves on the future generation of “exascale” supercomputers.

Kick-Off Meeting SPP2041

The members of the DFG Priority Programme "Computational Connectomics" met in Frankfurt

On 2 and 3 May 2018, the FIAS hosted the kick-off meeting of the DFG priority programme "SPP 2041 - Computational Connectomics". The goal of SPP 2041 is to better understand the interconnection and function of our brain and nervous system. Under the term "computational connectomics", the scientists involved use computer science and mathematics methods to better understand the structure of the connections between individual nerve cells or entire brain regions.

The FIAS foundation board member passed away on 5 March 2018 at the age of 90.

Born in 1927, the former General Director of Nestlé and holder of the Federal Cross of Merit, he has been committed for years to science and FIAS in particular. Since the founding days of FIAS, he has been a member of the Presidium of the Board of Trustees and was its first chairman. Helmut Maucher has accompanied and shaped the development of our institute with prudence and an eye for the essentials.

What's a quark-gluon-plasma?

Hannah Petersen explains it in the new podcast of Welt der Physik

"What came after the Big Bang is still a big question. We don't know exactly what happened there. But we know that the universe was probably filled with a quark-gluon plasma millions of seconds after the Big Bang. The big difference to today's universe was that it was extremely hot and extremely dense," FIAS Fellow Hannah Petersen explains in the podcast of Welt der Physik.

Deep Learning as a tool for Heavy Ion Physics

A Group of FIAS-Scientists used deep learning techniques to develop a tool for better understanding heavy ion collisions.

The present study is a proof of principle study where Long-Gang Pang, Kai Zhou, Nan Su, Hannah Petersen, Horst Stöcker and Xin-Nian Wang (University of California in Berkeley, USA) used more than 20.000 pictures from relativistic hydrodynamic simulations of heavy ion collisions in a convolution neural network (CNN) to classify two regions in the phase diagram.

How massive can neutron stars be?

Astrophysicists at FIAS and Goethe University set a new upper limit on the mass of neutron stars: it cannot be larger than 2.16 solar masses

FRANKFURT. Since their discovery in the 60's, scientists have worked on answering a crucial question: How massive do neutron stars actually get? Differently from black holes, in fact, these stars cannot be arbitrarily massive; past a certain finite limit in mass, no physical force in nature can contrast their enormous gravitational forces. For the first time, astrophysicists at Goethe University Frankfurt have succeeded in calculating a stringent upper bound on the maximum mass of neutron stars.
