Fermi Arcs in an antiferromagnet detected at BESSY II
An international cooperation has analyzed samples of NdBi crystals, which display interesting magnetic properties. In their experiments including measurements at BESSY II, they could find evidence for so called Fermi arcs in the antiferromagnetic sta.....»»
Here"s why we should put a gravitational wave observatory on the moon
Scientists detected the first long-predicted gravitational wave in 2015, and since then, researchers have been hungering for better detectors. But the Earth is warm and seismically noisy, and that will always limit the effectiveness of Earth-based de.....»»
IRIS beamline at BESSY II gets a new nanospectroscopy end station
The IRIS infrared beamline at the BESSY II storage ring now offers a fourth option for characterizing materials, cells and even molecules on different length scales. The team has extended the IRIS beamline with an end station for nanospectroscopy and.....»»
Recently discovered black hole is part of a nearby disrupted star cluster, study finds
European astronomers have investigated a recently detected black hole designated Gaia BH3. In their results, they found that the black hole is associated with a nearby disrupted star cluster known as ED-2. The finding is reported in a paper published.....»»
Pulsating Snake: First millisecond pulsar discovered in the galactic center
Astronomers from the Australia Telescope National Facility (ATNF) report the discovery of a new millisecond pulsar in the "Snake"—a radio filament in the galactic center. It is the first millisecond pulsar detected in the center of our galaxy. The.....»»
H5N1 strain of bird flu found in milk: WHO
The H5N1 bird flu virus strain has been detected in very high concentrations in raw milk from infected animals, the WHO said Friday, though how long the virus can survive in milk is unknown......»»
Astronomers discover the most metal-poor extreme helium star
Using the Southern African Large Telescope (SALT), astronomers have performed high-resolution observations of a recently detected extreme helium star designated EC 19529–4430. It turned out that EC 19529–4430 is the most metal deficient among the.....»»
Beyond equilibrium: Scientists investigate Floquet Fermi liquids
Researchers from Germany and Singapore have studied a non-equilibrium state of Fermi liquids called the Floquet Fermi liquid (FFL), which is formed when Fermi liquids are subjected to a periodic driving force and kept in contact with a fermionic bath.....»»
Hydrogen recombination found to be most plausible explanation for high levels of energy in stellar superflares
Although their primary purpose is to look for exoplanets, observatories like the Kepler Space Telescope and the Transiting Exoplanet Survey Satellite (TESS) have supplied a vast amount of data on stellar flares, detected with high-precision photometr.....»»
The brightest gamma ray burst ever seen came from a collapsing star
After a journey lasting about two billion years, photons from an extremely energetic gamma-ray burst (GRB) struck the sensors on the Neil Gehrels Swift Observatory and the Fermi Gamma-Ray Space Telescope on October 9th, 2022. The GRB lasted seven min.....»»
Stellar winds of three sun-like stars detected for the first time
An international research team led by a researcher from the University of Vienna has for the first time directly detected stellar winds from three sun-like stars by recording the X-ray emission from their astrospheres, and placed constraints on the m.....»»
New young and warm Jupiter-like exoplanet detected
An international team of astronomers reports the detection of a new young and warm exoplanet orbiting a distant star. The newfound alien world, designated TOI-4862 b (or NGTS-30 b), is similar in size and mass to Jupiter. The finding was published Ap.....»»
Researchers develop mechanism of electrical 180° switching of Néel vector in spin-splitting antiferromagnet
A research team led by The Hong Kong University of Science and Technology (HKUST) and Tsinghua University has theoretically proposed a new mechanism of electrical 180° switching of Néel vector and experimentally realized it in antiferromagnetic mat.....»»
Gravitational waves reveal “mystery object” merging with a neutron star
The so-called "mass gap" might be less empty than physicists previously thought. Enlarge / Artistic rendition of a black hole merging with a neutron star. LIGO/VIRGO/KAGRA detected a merger involving a neutron star and what might.....»»
Astronomers detect potential "glory effect" on a hellish distant world for the first time
Potential signs of the rainbow-like "glory effect" have been detected on a planet outside our solar system. Glory are colorful concentric rings of light that occur only under peculiar conditions......»»
Kerr-enhanced optical spring for next-generation gravitational wave detectors
The detection of gravitational waves stands as one of the most significant achievements in modern physics. In 2017, gravitational waves from the merger of a binary neutron star were detected for the first time which uncovered crucial information abou.....»»
Is the universe really a "dark forest" full of hostile aliens in hiding?
We have no good reason to believe that aliens have ever contacted Earth. Sure, there are conspiracy theories and some rather strange reports about harm to cattle, but nothing credible. Physicist Enrico Fermi found this odd. His formulation of the puz.....»»
Astronomers find 10 new millisecond pulsars in globular cluster Terzan 5
Using the MeerKAT radio telescope, an international team of astronomers has detected 10 new millisecond pulsars in a Galactic globular cluster known as Terzan 5. The finding, which makes Terzan 5 the most pulsar-rich globular cluster, was reported in.....»»
Cloud Active Defense: Open-source cloud protection
Cloud Active Defense is an open-source solution that integrates decoys into cloud infrastructure. It creates a dilemma for attackers: risk attacking and being detected immediately, or avoid the traps and reduce their effectiveness. Anyone, including.....»»
