Listening to quantum radio

Researchers at Delft University of Technology have created a quantum circuit to listen to the weakest radio signal allowed by quantum mechanics. This new quantum circuit opens the door to possible future applications in areas ...

In colliding galaxies, a pipsqueak shines bright

In the nearby Whirlpool galaxy and its companion galaxy, M51b, two supermassive black holes heat up and devour surrounding material. These two monsters should be the most luminous X-ray sources in sight, but a new study using ...

Team puts forth ideas on the nature of dark matter

Dark energy and dark matter comprise 96 percent of the total mass of the universe. Two main hypotheses about the nature of dark matter are presently debated. One posits that dark matter consists of massive compact halo objects; ...

Expression of stop bands in forward volume spin waves

A research group led by assistant Professor Taichi Goto at Toyohashi University of Technology has, for the first time, demonstrated stop bands that prevent propagation of specific frequency components of forward volume spin ...

Spintronics 'miracle material' put to the test

When German mineralogist Gustav Rose stood on the slopes of Russia's Ural Mountains in 1839 and picked up a piece of a previously undiscovered mineral, he had never heard of transistors or diodes or had any concept of how ...

A guide to hunting zombie stars

Apparently not all supernovas work. And when they fail, they leave behind a half-chewed remnant, still burning from leftover heat but otherwise lifeless: a zombie star. Astronomers aren't sure how many of these should-be-dead ...

Holey graphene as Holy Grail alternative to silicon chips

Graphene, in its regular form, does not offer an alternative to silicon chips for applications in nanoelectronics. It is known for its energy band structure, which leaves no energy gap and no magnetic effects. Graphene antidot ...

Tangled magnetic fields power cosmic particle accelerators

Magnetic field lines tangled like spaghetti in a bowl might be behind the most powerful particle accelerators in the universe. That's the result of a new computational study by researchers from the Department of Energy's ...
