Kiel Physicists Succeed in Describing Thermodynamic Properties of Highly Excited Electrons

It is the “drosophila” of modern physics: the uniform electron gas. Just as the fruit fly is used to describe the principles of genetics this model of a gas can be used to investigate important characteristics of eletctrons. This model, also known as jellium, describes the properties of electrons in metals, in molecules and in clusters of atoms.

Luminous Infrared Galaxy Swirls in the Darkness of the Cosmos

Though it resembles a peaceful rose swirling in the darkness of the cosmos, NGC 3256 is actually the site of a violent clash. This distorted galaxy is the relic of a collision between two spiral galaxies, estimated to have occurred 500 million years ago. Today it is still reeling in the aftermath of this event.
