Astronomers will "Hear" More Colliding Black Holes Through Gravitational Waves

The coalescence of two black holes -- a very violent and exotic event -- is one of the most sought-after observations of modern astronomy. But, as these mergers emit no light of any kind, finding such elusive events has been impossible so far.

Brown Dwarf Stars Act More Like Supersized Planets, Host Powerful Aurora Displays

Brown dwarf stars host powerful aurora displays just like planets, astronomers have discovered.

Trapped Atomic Ion System Could Potentially Support Symmetry-Protected Quantum State

Symmetry permeates nature, from the radial symmetry of flowers to the left-right symmetry of the human body. As such, it provides a natural way of classifying objects by grouping those that share the same symmetry.

Undergraduates Discover Densest Ultracompact Dwarf Galaxies

Two undergraduates at San José State University have discovered two galaxies that are the densest known. Similar to ordinary globular star clusters but a hundred to a thousand times brighter, the new systems have properties intermediate in size and luminosity between galaxies and star clusters.

First Results from Run 2 of Large Hadron Collider Presented at EPS-HEP2015

The world particle-physics community has convened in Vienna for the 2015 European Physical Society Conference on High Energy Physics (EPS-HEP2015), where the latest results in the field are being presented and discussed.

Environment Provides Fast Control of Atom-Optical System in Cavity Quantum ElectroDynamics

Control systems are ubiquitous, and as essential as they are easy to overlook. For instance, turning the dial on a thermostat feels as trivial as moving a piece on a board game, but this control system is actually quite complex.

Back and Forth may not be Equal Distances in Quantum Photonic Circuits

Quantum technology based on light (photons) has great potential for radically new information technology based on photonic circuits. Up to now, the photons in quantum photonic circuits have behaved in the same way whether they moved forward or backward in a photonic channel.
