Milestone in physics: gravitational waves detected with the laser system from LZH

12.02.2016

An international researcher team of the LIGO Scientific Collaboration (LSC), the Albert Einstein Institute (AEI) Hannover and many other institutions have proven Albert Einstein‘s theory of general relativity 100 years after its development: they succeeded in recording the merger of two black holes.

The resulting gravitational wave was measured already in September 2015; yesterday, the evaluation of the data was published in the Physical Review Letters and presented to the world press.

LZH

For more than ten years, the AEI and the Laser Zentrum Hannover e.V. (LZH) have put R&D efforts into the development of laser systems for the LIGO (Laser Interferometer Gravitational Wave Observatory) gravitational wave detectors.

The lasers of the LIGO detectors were jointly manufactured and integrated into the US observatories as a ready-to-run system by the LZH, the AEI and the LZH spin-off company neoLASE. The gravitational wave detected now was recorded by the Enhance LIGO (eLIGO) model.

The Advanced LIGO (aLIGO) systems that were put into operation in the meantime have a five times higher output power compared to the previous lasers. Under these circumstances, chances to detect further gravitational waves are significantly higher.

With this high-tech measurement instrument, a reliable basis was created for future research in gravitational physics in Hannover and worldwide.

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: RAVAN CubeSat measures Earth's outgoing energy

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
