Astronomers from the universities of Hertfordshire and Kent have received a grant which will allow them to map large areas of the sky 1000 times faster than with current technology.
The universities, in conjunction with the University of British Columbia and the Joint Astronomy Centre, have been awarded 1,500 hours of observation and survey time on the James Clerk Maxwell Telescope (JCMT) at the Mauna Kea Observatories in Hawaii. The award, which is part of the JCMT Major Legacy Surveys, has been valued by the Particle Physics and Astronomy Research Council (PPARC) at £2.1 million.
The study, which will begin in 2006 and end in 2011 and is known as SASSy (SCUBA-2 All-Sky Survey), intends to search a large fraction of the sky for unknown and invisible star-forming clouds and galaxies. A new £12 million SCUBA-2 camera within the telescope will allow the academics to access the cold hidden universe of distant dusty star-forming galaxies and nearby cold star-forming clouds.

Abrupt motion sharpens x-ray pulses

Physicists Design Ultrafocused Pulses

Spectrally narrow x-ray pulses may be “sharpened” by purely mechanical means. This sounds surprisingly, but a team of theoretical and experimental physicists developed and realized such a method. It is based on fast motions, precisely synchronized with the pulses, of a target interacting with the x-ray light. Thereby, photons are redistributed within the x-ray pulse to the desired spectral region.
A team of theoretical physicists from the MPI for Nuclear Physics (MPIK) in Heidelberg has developed a novel method to intensify the spectrally broad x-ray...
Physicists working with researcher Oriol Romero-Isart devised a new simple scheme to theoretically generate arbitrarily short and focused electromagnetic fields. This new tool could be used for precise sensing and in microscopy.
Microwaves, heat radiation, light and X-radiation are examples for electromagnetic waves. Many applications require to focus the electromagnetic fields to...
Strong light-matter coupling in these semiconducting tubes may hold the key to electrically pumped lasers
Light-matter quasi-particles can be generated electrically in semiconducting carbon nanotubes. Material scientists and physicists from Heidelberg University...
Fraunhofer IPA has developed a proximity sensor made from silicone and carbon nanotubes (CNT) which detects objects and determines their position. The materials and printing process used mean that the sensor is extremely flexible, economical and can be used for large surfaces. Industry and research partners can use and further develop this innovation straight away.
At first glance, the proximity sensor appears to be nothing special: a thin, elastic layer of silicone onto which black square surfaces are printed, but these...
