Galaxy formation simulated without dark matter

For the first time, researchers from the Universities of Bonn and Strasbourg have simulated the formation of galaxies in a universe without dark matter. To replicate this process on the computer, they have instead modified ...

Laser-based prototype probes cold atom dynamics

By tracking the motions of cold atom clouds, astronomers can learn much about the physical processes which play out in the depths of space. To make these measurements, researchers currently use instruments named 'cold atom ...

Discovering exoplanets with gravitational waves

In a recent paper in Nature Astronomy, researchers from the Max Planck Institute for Gravitational Physics (Albert Einstein Institute/AEI) in Potsdam and from the French Alternative Energies and Atomic Energy Commission (CEA) ...

A high-precision test bench for LISA technology

For the first time, it has been possible to test laser measurement technology for LISA in laboratories almost under mission conditions. A team of researchers led by the Max Planck Institute for Gravitational Physics (Albert ...

Discovering new particles using black holes

Some theories that go beyond the Standard Model of particle physics predict the existence of new ultralight particles, with masses far below the lightest known particles in nature. These particles have such very weak interactions ...

A brief history of black holes

Late in 2018, the gravitational wave observatory, LIGO, announced that they had detected the most distant and massive source of ripples of spacetime ever monitored: waves triggered by pairs of black holes colliding in deep ...
