Study Proposes Possible Existence of Stupendously Large Black Holes

A new research work proposes the prospective occurrence of “stupendously large black holes” (SLABS), which are much larger than the supermassive black holes (SMBHs) already spotted at the centers of galaxies.

Nanoscale Diamonds Generate More Efficient Electron Beams

Beam-driven wakefield acceleration methods are potential candidates for upcoming large-scale machines, such as linear colliders and X-ray free-electron lasers, as they are capable of improving efficiency and decrying operation costs.

New Phononic Switch Holds Great Promise for Spintronics and Quantum Computing

Scientists at the U.S. Department of Energy's Ames Laboratory and collaborators at Brookhaven National Laboratory and the University of Alabama at Birmingham have discovered a new light-induced switch that twists the crystal lattice of the material, switching on a giant electron current that appears to be nearly dissipationless.

New Protocol Simulates Atomic Structure of Solid/Liquid Interface

Computer simulations are known to have immense potential to speed up the molecular design of green energy technologies, for example, novel systems meant for solar energy usage and electrical energy storage, and also carbon dioxide capture from the surroundings.

Physicists Discover a New Way to Extract Energy From Black Holes

A remarkable prediction of Einstein's theory of general relativity--the theory that connects space, time, and gravity--is that rotating black holes have enormous amounts of energy available to be tapped.

Gamma-Burst Monitor Detects Signals of Magnetar Flare in Neighbouring Galaxies

Apart from black holes, magnetars may be the most extreme stars in the universe. With a diameter less than the length of Manhattan, they pack more mass than that of our sun, wield the largest magnetic field of any known object -- more than 10 trillion times stronger than a refrigerator magnet -- and spin on their axes every few seconds.

Study Shows Short Gamma-Ray Bursts Came from Another Possible Source

Earth gets blasted by mild short gamma-ray bursts (GRBs) most days. But sometimes a giant flare like GRB 200415A arrives at our galaxy, sweeping along energy that dwarfs our sun. In fact, the most powerful explosions in the universe are gamma-ray bursts.
