Nanoparticles show promise as inexpensive, durable and effective scintillators
A team of industrial and university researchers has shown that nanoparticles with sizes smaller than 10 nanometers - approximately the width of a cell membrane - can be successfully incorporated into scintillation devices capable of detecting and measuring a wide energy range of X-rays and gamma rays emitted by nuclear materials.

Possible Origin of Cosmic Rays Revealed with Gamma Rays
An international team of astronomers (including the UK) has produced the first ever image of an astronomical object using high energy gamma rays, helping to solve a 100 year old mystery - an origin of cosmic rays. Their research, published in the Journal Nature on November 4th, was carried out using the High Energy Stereoscopic System (H.E.S.S.), an array of four telescopes, in Namibia,...

Physicists find evidence for highest energy photons ever detected from Milky Way's equator
Physicists at nearly a dozen research institutions, including New York University, have discovered evidence for very high energy gamma rays emitting from the Milky Way, marking the highest energies ever detected from the galactic equator. View More (2005-12-14)
Gamma rays from galactic center could be evidence of dark matter
Gamma-ray photons seen emanating from the center of the Milky Way galaxy are consistent with the intriguing possibility that dark-matter particles are annihilating each other in space, according to research submitted by UC Irvine astrophysicists to the American Physical Society journal Physical Review D.

Searching the heavens
A new space mission, due to launch this month, is going to shed light on some of the most extreme astrophysical processes in nature - including pulsars, remnants of supernovae, and supermassive black holes. View More (2008-05-01)
Integral identifies supernova rate for Milky Way
Using ESA's Integral observatory, an international team of researchers has been able to confirm the production of radioactive aluminium (Al 26) in massive stars and supernovae throughout our galaxy and determine the rate of supernovae-one of its key parameters. View More (2006-01-09)
ESA steps towards a great black hole census
Astronomers using ESA's orbiting gamma-ray observatory, Integral, have taken an important step towards estimating how many black holes there are in the Universe. View More (2006-09-08)
Astronomers find first ever gamma ray clock
Astronomers using the H.E.S.S. telescopes have discovered the first ever modulated signal from space in Very High Energy Gamma Rays - the most energetic such signal ever observed. View More (2006-11-28)
High-energy astrophysics puzzle
Blazars are the brightest of active galactic nuclei, and many emit very high-energy gamma rays. New observations of a blazar known as PKS 1424+240 show that it is the most-distant known source of very high-energy gamma rays. But its emission spectrum appears highly unusual. View More (2013-04-24)
First simultaneous observation of a gamma-ray burst in the X-ray and in the very high energy gamma ray band
For the first time a gamma-ray burst (GRB) has been observed simultaneously in the X-ray and in the very high energy gamma ray band. View More (2005-08-24)
NASA's Fermi Telescope Probes Dozens of Pulsars
With NASA's Fermi Gamma-ray Space Telescope, astronomers now are getting their best look at those whirling stellar cinders known as pulsars. View More (2009-07-07)
NASA's Fermi Closes on Source of Cosmic Rays
New images from NASA's Fermi Gamma-ray Space Telescope show where supernova remnants emit radiation a billion times more energetic than visible light. The images bring astronomers a step closer to understanding the source of some of the universe's most energetic particles -- cosmic rays. View More (2010-02-17)
New space telescope aims to seek out and record explosive gamma ray bursts.
A state of the art space telescope built by scientists at UCL will make its way to the Goddard Space Flight Centre in Maryland, USA on a mission to unravel the mysteries of the universes gamma rays. The telescope - called UVOT - will be one of three telescopes on a special NASA orbiting space observatory planned for launch in 2003. The observatory , called SWIFT, has been specially designed to... View More (2002-05-31)
Iowa State researchers contribute to discovery of gamma rays from starburst galaxy
Iowa State University astrophysicists contributed to the recent discovery that a galaxy quickly creating new stars is also a source of high energy gamma rays. View More (2009-11-03)
Biggest ever Gamma Ray search starts in Namibia
The world's most sensitive Gamma Ray telescopes are being inaugurated in Namibia (in Southwest Africa) on September 3rd. The High Energy Stereoscopic System (H.E.S.S.), a European/African collaboration in which the UK is a partner, will look for Gamma Rays produced by the most energetic particles in the Universe. The array initially consists of four telescopes, the first of which will become... View More (2002-08-28)
Astrophysicists Solve Mystery in Milky Way Galaxy
A team of astrophysicists has solved a mystery that led some scientists to speculate that the distribution of certain gamma rays in our Milky Way galaxy was evidence of a form of undetectable "dark matter" believed to make up much of the mass of the universe. View More (2009-07-09)
High Energy Mystery lurks at the Galactic Centre
A mystery lurking at the centre of our own Milky Way galaxy - an object radiating high-energy gamma rays - has been detected by an international team of astronomers. Their research, published today (September 22nd) in the Journal Astronomy and Astrophysics, was carried out using the High Energy Stereoscopic System (H.E.S.S.), an array of four telescopes, in Namibia, South-West Africa.

Everyone wants gamma-ray eyes!
Even before ESA`s Integral gamma-ray observatory was launched, astronomers were competing to win time to use this state-of-the-art observatory. The Integral Science Operations Centre in Noordwijk, The Netherlands, received hundreds of excellent proposals. ESA expects Integral to revolutionise the way we think about the violent Universe. Understandably, everyone wants to play a part in that... View More (2002-10-29)
Starburst galaxy sheds light on longstanding cosmic mystery
An international collaboration that includes scientists from the University of Delaware's Bartol Research Institute in the Department of Physics and Astronomy has discovered very-high-energy gamma rays in the Cigar Galaxy (M82), a bright galaxy filled with exploding stars 12 million light years from Earth.

Nuclear detector
New materials hold promise for better detection of nuclear weapons
Northwestern University scientists have developed new materials that can detect hard radiation, a very difficult thing to do. The method could lead to a handheld device for detecting nuclear weapons and materials, such as a "nuclear bomb in a suitcase" scenario. View More (2011-09-13)
