Combination of Astrophysical Measurements Provides New Estimates of Neutron Star Size

A combination of astrophysical measurements has allowed researchers to put new constraints on the radius of a typical neutron star and provide a novel calculation of the Hubble constant that indicates the rate at which the universe is expanding.

New Research Measures Elusive Majorana Quantum States

A team of theoretical and experimental physicists have designed a new ultra-thin material that they have used to create elusive quantum states. Called one-dimensional Majorana zero energy modes, these quantum states could have a huge impact for quantum computing.

Researchers Use Quantum Simulation to Explore a "Bosonization" Phenomenon

In the text book of quantum mechanics, it was introduced that bosons and fermions, two types of elementary particles that build the universe, behave in a drastically different way. For example, bosons can share the same quantum state while fermions of the same kind cannot but fill available quantum states one by one.

Researchers Observe Dark Matter that Confirms Origin, Evolution of Universe

To date, over 50% of the matter in the universe has remained invisible to human beings. But astrophysicists had a notion where it might be located: In supposed filaments, incomprehensibly huge thread-like structures of hot gas surrounding and connecting galaxies and clusters of galaxies.

'Modified Gravity' Offers a Viable Explanation for Cosmological Dilemma

An international research team has recently published a study challenging that a rival concept to the well-known hypothesis of dark matter can more precisely estimate a galactic phenomenon that seems to defy the traditional rules of gravity.

Scientists Detect Radio Bursts Emanating from the Constellation Boötes

By monitoring the cosmos with a radio telescope array, a Cornell University-led international team of scientists has detected radio bursts emanating from the constellation Boötes. The signal could be the first radio emission collected from a planet beyond our solar system.

Researchers Realize Quantum Anomalous Hall Effect in Multilayered Insulator

New energy-efficient electronic devices may be possible thanks to research that demonstrates the quantum anomalous Hall (QAH) effect -- where an electrical current does not lose energy as it flows along the edges of the material -- over a broader range of conditions.

Research Improves Understanding of the Most-Distant Known Astrophysical Object

New work from an international team of astronomers including Carnegie's Gregory Walth improves our understanding of the most-distant known astrophysical object-- GN-z11, a galaxy 13.4 billion light-years from Earth.

Study Sheds Light on Surprising Choreography Among Spinning Atoms

A new study illuminates surprising choreography among spinning atoms. In a paper appearing in the journal Nature, researchers from MIT and Harvard University reveal how magnetic forces at the quantum, atomic scale affect how atoms orient their spins.

Researchers Discover Curious Starless Binary System of Brown Dwarfs

Star-forming processes sometimes create mysterious astronomical objects called brown dwarfs, which are smaller and colder than stars, and can have masses and temperatures down to those of exoplanets in the most extreme cases. Just like stars, brown dwarfs often wander alone through space, but can also be seen in binary systems, where two brown dwarfs orbit one another and travel together in the galaxy.
