This innovative instrument is aimed to hunt the elusive gravitational waves using extremely sophisticated technological solutions.
On July 23rd in Cascina, near Pisa (Italy), the new Virgo interferometer will be inaugurated. The innovative Virgo gravitational-wave-detector is the outcome of more than ten years of collaborative research and development between the National Institute of Nuclear Physics (Infn, Italy) and the National Scientific Research Centre (Cnrs, France). Letizia Moratti, Italys Minister for Education and Research, and Claudie Haigneré, the French Minister for Research and New Technologies, will participate in the inauguration ceremony. Journalists are also being invited to tour the scientific infrastructure and interview researchers.
The existence of gravitational waves is one of the most fascinating puzzles of modern physics. They are predicted by Albert Einsteins general theory of relativity, and their existence has been demonstrated indirectly (Joseph. H. Taylor and Russell A. Hulse received the Nobel Prize for this discovery in 1993), but until now it has never been possible to observe them directly. "Gravitational waves are elusive perturbations of space-time curvature, produced by material bodies when accelerating, and can be considered similar to electromagnetic waves emitted by charged particles when they are accelerating. They are difficult to detect, however, because of the fact that they are extremely weak perturbations and, at the best, we can only hope to register those produced by huge phenomenona, like the explosion of a supernova, the interaction between a neutron star and a black hole, or the fusion of two neutron stars belonging to a binary system", says Enzo Iarocci, president of Infn.

A new manufacturing technique uses a process similar to newspaper printing to form smoother and more flexible metals for making ultrafast electronic devices.
The low-cost process, developed by Purdue University researchers, combines tools already used in industry for manufacturing metals on a large scale, but uses...
For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
