Exploding star provides hint on how dark matter warps light in the universe
An exploding star has been seen by astronomers four separate times as a result of dark matter affecting the image, an Australian researcher has revealed.

A team of international scientists studying space using the Hubble Telescope found a supernova explosion appeared multiple times in different places due to the impact of gravitation on light :: Read the full article »»»»

Generation and Near-Field Imaging of Airy Surface Plasmons

In a paper published on September 6, 2011 in Physical Review Letters researchers of  the Australian National University, CUDOS and Friedrich-Schiller University have for the first time detailed Airy beams distinct properties, namely the beams nondiffracting nature, self-accelerating trajectory and self- healing – after passing through surface defects – properties. The researchers believe that the demonstration of Airy plasmon beams opens new opportunities for selective on-chip manipulation of nanoparticles, optical sensing, photonic circuitry, and magneto electronics. They anticipate that their results will open further opportunities for generation of subwavelength Airy beams in plasmonics or other surface systems, as recently attempted in spin waves. Finally, novel techniques for nonlinear Airy plasmon generation can be explored, combining the recent nonlinear generation of free-space Airy beams and nonlinear generation of surface plasmons.
