Color of Supernovae During Specific Phase Could Help Detect Oldest Supernovae in the Universe

An international collaboration led by the Kavli Institute for the Physics and Mathematics of the Universe (Kavli IPMU) have discovered that the color of supernovae during a specific phase could be an indicator for detecting the most distant and oldest supernovae in the Universe - more than 13 billion years old.

Research Findings Suggest Use of Controllable Quantum Systems to Investigate Fundamental Aspects of Nature

Using a small quantum system consisting of three superconducting qubits, researchers at UC Santa Barbara and Google have uncovered a link between aspects of classical and quantum physics thought to be unrelated: classical chaos and quantum entanglement.

Astronomers Produce Deepest, Most Comprehensive View of Orion Nebula to Date

ESO’s HAWK-I infrared instrument on the Very Large Telescope (VLT) in Chile has been used to peer deeper into the heart of Orion Nebula than ever before. The spectacular picture reveals about ten times as many brown dwarfs and isolated planetary-mass objects than were previously known.

Researchers Explore Radiation Tolerance of AlGaN/GaN High Electron Mobility Transistors

When it comes to putting technology in space, size and mass are prime considerations. High-power gallium nitride-based high electron mobility transistors (HEMTs) are appealing in this regard because they have the potential to replace bulkier, less efficient transistors, and are also more tolerant of the harsh radiation environment of space.

Neutrinos Produced in Core of Supernova Highly Localised Compared to Neutrinos from other Sources

Neutrinos are elementary particles known for displaying weak interactions. As a result, neutrinos passing each other in the same place hardly notice one another. Yet, neutrinos inside a supernova collectively behave differently because of their extremely high density.

Astronomers Guide Citizen Scientists in Discovering Rare Galaxy Cluster 1.2 Billion Light Years Away

Two volunteer participants in the international crowdsourcing research project, Galaxy Zoo, have discovered a rare galaxy cluster 1.2 billion light years away with help from astronomers at the University of Minnesota.

Switching Quantum Gates with Photons Could Enhance Information Transfer in Quantum Computers

Light particles completely ignore each other. In order that these particles can nevertheless switch each other when processing quantum information, researchers at the Max Planck Institute of Quantum Optics in Garching have now developed a universal quantum gate.

Researchers Optimize Defects to Enhance Current-Carrying Capacity of High-Temperature Superconducting Wires

High-temperature superconducting materials hold enormous promise for a variety of different applications because of their ability to transmit a current without any dissipation at relatively high temperatures — up to around 90 Kelvin (about -300° F), which permits cooling with liquid nitrogen.

Researchers Use Single Electron to Couple Nuclear Spins of Distant Atoms

For the first time, researchers at the University of Basel in Switzerland have coupled the nuclear spins of distant atoms using just a single electron. Three research groups took part in this complex experiment, the results of which have now been published in the journal Nature Nanotechnology.

Materials Researchers Develop Faster Technique to Apply Silica Coatings on Quantum Dot Nanorods

Materials researchers at North Carolina State University have fine-tuned a technique that enables them to apply precisely controlled silica coatings to quantum dot nanorods in a day – up to 21 times faster than previous methods. In addition to saving time, the advance means the quantum dots are less likely to degrade, preserving their advantageous optical properties.

Astronomers Discover that Elliptical Galaxies are Essentially Giant Disk Galaxies

Astronomers have believed since the 1960s that a galaxy dubbed UGC 1382 was a relatively boring, small elliptical galaxy. Ellipticals are the most common type of galaxy and lack the spiral structure of disks like the Milky Way we call home.

Follow-Up Investigation Shows Impact of Supernovae Cosmic Rays on Earth Atmosphere

Research published in April provided “slam dunk” evidence of two prehistoric supernovae exploding about 300 light years from Earth. Now, a follow-up investigation based on computer modeling shows those supernovae likely exposed biology on our planet to a long-lasting gust of cosmic radiation, which also affected the atmosphere.

Physicists Split and Smash Ultracold Atoms to Observe Theoretical Principle of Quantum Mechanics

Physicists from New Zealand's University of Otago have used steerable 'optical tweezers' to split minute clouds of ultracold atoms and slowly smash them together to directly observe a key theoretical principle of quantum mechanics.

UC Riverside-Led Research Team Explains Why Galaxies Stop Creating Stars

Galaxies come in three main shapes - elliptical, spiral (such as the Milky Way) and irregular. They can be massive or small. To add to this mix, galaxies can also be blue or red. Blue galaxies are still actively forming stars. Red ones mostly are not currently forming stars, and are considered passive.
