Study Sheds New Light on Role of Angular Momentum in Nuclear Fission

A set of experiments performed at the ALTO particle accelerator facility based in Orsay, France, has demonstrated that the fragments ensuing from nuclear fission achieve their inherent angular momentum (or spin) only after the fission reactions and not before them, as is generally believed.

New Evidence of Cold Gas Pipelines Feeding Early, Massive Galaxies Found

To come into being, galaxies need a steady diet of cold gases to undergo gravitational collapse. The larger the galaxy, the more cold gas it needs to coalesce and to grow.

Study Proposes a Mechanism for Formation of Supermassive Black Holes from Dark Matter

A new theoretical study has proposed a novel mechanism for the creation of supermassive black holes from dark matter. The international team find that rather than the conventional formation scenarios involving 'normal' matter, supermassive black holes could instead form directly from dark matter in high density regions in the centres of galaxies.

QUASAR Project Aims to Lay the Foundations for Industrial Production of Quantum Processors

The quantum computer race is in full swing. Germany has long been one of the world leaders in basic research. An alliance between Forschungszentrum Jülich and the semiconductor manufacturer Infinion, together with institutes of the Fraunhofer-Gesellschaft (IAF, IPMS) as well as the Leibniz Association (IHP, IKZ), the universities of Regensburg and Konstanz and the quantum start-up HQS, now aims to apply the results to industrial production.

A New Method to Produce Beams of Entangled Atoms

Heads or tails- If we toss two coins into the air, the result of one coin toss has nothing to do with the result of the other. Coins are independent objects. In the world of quantum physics, things are different: quantum particles can be entangled, in which case they can no longer be regarded as independent individual objects, they can only be described as one joint system.

New Project Aims to Combine Superconductor with Semiconductor Technology

The next generation of supercomputers - including quantum computers - is at a crucial point: Tomorrow's high-performance computers are at their physical limit in terms of miniaturization of their components; at the same time, they must be more energy-efficient and increase in performance.

Magnetic Field Misalignment Regulates Astrophysical Jet Formation

Matter outflows are common attributes arising from systems driven by compact objects like active galactic nuclei, black holes, accreting objects like Young Stellar Objects (YSO), pulsar wind nebulae, and mature stars like the sun.

Merger of Two Boson Stars Could Explain Existence of Dark Matter

An international research team has now demonstrated that the heaviest collision of black holes to be ever visualized and created by the gravitational-wave GW190521 could be more mysterious than previously believed—that is, the merger of a pair of boson stars.

New Production Process Makes Micron-Sized YIG Structures Universally Usable

New storage and information technology requires new higher performance materials. One of these materials is yttrium iron garnet, which has special magnetic properties. Thanks to a new process, it can now be transferred to any material.

Newly Proposed Heavy Particle Could Help Unravel Dark Matter Mysteries

Scientists from the University of Granada have proposed a new particle which, in contrast to the Higgs boson discovered in 2012 at CERN’s Large Hadron Collider after a four-decade quest, is so heavy that it is impossible to produce directly even in this collider.

X-Ray Telescopes Reveal Key Component of Famous Supernova Remnant

For more than 30 years, researchers have been searching for a reclusive neutron star in the famous Supernova 1987A (SN 1987A).

Researchers Develop New Algorithm to Analyze Large Scale Cosmic Structures

The Instituto de Astrofísica de Canarias (IAC) has led an international team which has developed an algorithm called COSMIC BIRTH to analyze large scale cosmic structures. This new computation method will permit the analysis of the evolution of the structure of dark matter from the early universe until the formation of present day galaxies. This work was recently published in the journal Monthly Notices of the Royal Astronomical Society (MNRAS).

Russian Scientists Propose a New Mechanism for Neutrino Production in Quasars

Scientists of the P. N. Lebedev Physical Institute of the Russian Academy of Sciences (LPI RAS), the Moscow Institute of Physics and Technology (MIPT) and the Institute for Nuclear Research of RAS (INR RAS) studied the arrival directions of astrophysical neutrinos with energies more than a trillion electronvolts (TeV) and came to an unexpected conclusion: all of them are born near black holes in the centers of distant active galaxies powerful radio sources. Previously, only neutrinos with the highest energies were assumed to be obtained in sources of this class.

NASA's Swift Used for Tracing a Neutrino to Star-Shredding Black Hole

For only the second time, astronomers have linked an elusive particle called a high-energy neutrino to an object outside our galaxy. Using ground- and space-based facilities, including NASA's Neil Gehrels Swift Observatory, they traced the neutrino to a black hole tearing apart a star, a rare cataclysmic occurrence called a tidal disruption event.
