Deepest look yet into the heart of a quasar
Deepest look yet into the heart of a quasar
International team observes innermost structure of quasar 3C 273 At the core of almost every galaxy is a supermassive black hole. But there are many different types. Quasars, for example, are one of the brightest and most active types of galaxy centres. An international group, including researchers from the Max Planck Institute for Radio Astronomy in Bonn, presents new observations of the first quasar ever identified.

Researchers discover an important clue as to what mechanism drives the solar wind Using observational data from the U.S. weather satellites GOES, a team of researchers led by the Max Planck Institute for Solar System Research (MPS) in Germany has taken an important step toward unlocking one of the Sun-s most persevering secrets: How does our star launch the particles constituting the solar wind into space? The data provide a unique view of a key region in the solar corona to which researchers have had little access so far.

International team observes the innermost structure of the jet of 3C 273 At the core of almost every galaxy is a supermassive black hole. But there are many different types. Quasars, for example, are one of the brightest and most active varieties of galactic centers. An international group, including researchers from the Max Planck Institute for Radio Astronomy in Bonn, Germany, presents new observations of the first quasar ever identified.

Elusive carbonic acid: it really exists!
Elusive carbonic acid: it really exists!
Neutrons from FRM II expose crystal structure of carbonic acid The existence of carbonic acid has long been the subject of debate: theoretically real, but practically impossible to detect. That is because the compound decomposes at the Earth's surface. A German-Chinese team of researchers working at the FRM II Research Neutron Source at the Technical University of Munich (TUM) has now made the crystalline structure of carbonic acid molecules visible for the first time.

Long-range information transport in antiferromagnets
Physicists at JGU discovered: Antiferromagnets are suitable for transporting spin waves over long distances Smaller, faster, more powerful: The demands on microelectronic devices are high and continue to rise. However, if chips, processors and the like are based on electric current, there are limits to miniaturization.

Researchers control individual light quanta at very high speed
A team of German and Spanish researchers from Valencia, Münster, Augsburg, Berlin and Munich have succeeded in controlling individual light quanta to an extremely high degree of precision. In the "Nature Communications" journal, the researchers report how, by means of a soundwave, they switch individual photons on a chip back and forth between two outputs at gigahertz frequencies.

Problem solved in organic chemistry
Problem solved in organic chemistry
In chemicals used in agriculture, as well as in pharmaceuticals and a variety of materials, pyridines are often found as so-called functional units which decisively determine the chemical properties of substances. Pyridines belong to the group of ring-shaped carbon-hydrogen (C'H) compounds ("heterocycles"), and they contain a nitrogen atom (N).

Quantum technology for cancer imaging
Applied quantum mechanics in medicine Tracing the metabolism of tumor cells using magnetic resonance imaging (MRI) has not been feasible in routine clinical settings hitherto. Now, an interdisciplinary research team including the Technical University of Munich (TUM) is working to advance the development of a quantum-based hyperpolarizer so that it can be deployed in clinical applications.

Magnetic Quantum Fluid: Extremely Fluid in Two Ways
Magnetic Quantum Fluid: Extremely Fluid in Two Ways
Heidelberg physicists demonstrate the coexistence of superfluids in ultracold atomic clouds Two superfluids can exist at the same time in ultracold atomic clouds. Until now, their coexistence could not be observed experimentally. Now, however, physicists from Heidelberg University have demonstrated such a magnetic quantum fluid - it is fluid in two ways - in an atomic gas.

Clever method for separating nano-components
Clever method for separating nano-components
Physicists from Friedrich Schiller University Jena, together with colleagues from Düsseldorf, Gothenburg, Lyngby and Trieste have developed an ingenious solution for separating bonded nano-components. Their idea is to immerse the nano-components in a solvent near its critical point. In the experimental setup, they succeeded in separating the components in a controllable fashion by only changing the temperature of the solvent.

IceCube neutrinos give us first glimpse into the inner depths of an active galaxy
IceCube neutrinos give us first glimpse into the inner depths of an active galaxy
Mainz-based scientists have been members of the IceCube consortium since 1999 For the first time, an international team of scientists found evidence of high-energy neutrino emission from NGC 1068, also known as Messier 77, an active galaxy in the constellation of Cetus and one of the most familiar and well-studied galaxies to date.

Wobbling like a spinning-top - surprising observations of X-ray pulsar
Wobbling like a spinning-top - surprising observations of X-ray pulsar
An X-ray pulsar is a rotating magnetized neutron star. The very first direct measurement of the polarization of an X-ray pulsar by the Imaging X-ray Polarimetry Explorer (IXPE) space telescope has challenged previous models of such systems. The degree of polarization of the X-ray pulsar Hercules X-1 was much lower than theoretically predicted, so astrophysicists are now having to reconsider their basic ideas about the geometry and structure of matter flows.

Lightest-ever neutron star or strange quark matter?
The lightest neutron star so far found is located at the center of the supernova remnant HESS J1731'347 . Dr. Victor Doroshenko, Dr. Valery Suleimanov, Dr. Gerd Pühlhofer and Professor Andrea Santangelo from the High Energy Astrophysics section of the University of Tübingen's Institute of Astronomy and Astrophysics discovered the unusual object with the help of X-ray telescopes in space.

The conundrum of the anomalous magnetic moment of the muon
The conundrum of the anomalous magnetic moment of the muon
New calculations based on fundamental theories deviate from the currently accepted theoretical value The anomalous magnetic moment of the muon is a crucial parameter in particle physics as it allows for precision tests of the established Standard Model. A new measurement of this quantity in 2021 caused a furore as it reaffirmed a significant deviation from the theoretical prediction - in other words, the anomalous magnetic moment is greater than anticipated.

Researchers provide new insights into photosynthesis
Photosynthesis is the most important basis of life on Earth. In it, plants and single-cell algae use the energy of sunlight and convert this energy into sugar and biomass. In this process, oxygen is released. Plant biotechnologists and structural biologists from the Universities of Münster and Stockholm (Sweden) have clarified the structure of a new protein complex which catalyses energy conversion processes in photosynthesis.

Milestones achieved on the path to useful quantum technologies
Researchers at Paderborn and Ulm universities are developing the first programmable optical quantum memory Tiny particles that are interconnected despite sometimes being thousands of kilometres apart - Albert Einstein called this 'spooky action at a distance'. Something that would be inexplicable by the laws of classical physics is a fundamental part of quantum physics.
