Black hole winds are no longer as they used to be

During the first billion years of the universe, winds blown by supermassive black holes at the centers of galaxies were much more frequent and more powerful than those observed in today's galaxies, some 13 billion years later. ...

Light-infused particles go the distance in organic semiconductors

Polaritons offer the best of two very different worlds. These hybrid particles combine light and molecules of organic material, making them ideal vessels for energy transfer in organic semiconductors. They are compatible ...

Physicists embark on a hunt for a long-sought quantum glow

For "Star Wars" fans, the streaking stars seen from the cockpit of the Millennium Falcon as it jumps to hyperspace is a canonical image. But what would a pilot actually see if she could accelerate in an instant through the ...

Impact of black hole winds, radiation examined in new study

Black holes are regions of space where gravity is so strong that nothing can escape. New research is examining the radiation and winds emanating from black hole activity and shows how they may exert effects on nearby planets.

Using the principle of coherent feedback to cool a quantum system

We've all experienced the principle of feedback—for example, when we use a thermostat in conjunction with a heating system to regulate indoor temperature. The thermostat measures the current temperature, compares it with ...
