Title: Carbon-doped ZnO: A New Class of Room Temperature Dilute Magnetic Semiconductor Authors: Pan, H.; Yi, J. B.; Lin, J. Y.; Feng, Y. P.; Ding, J.; Van, L. H.; Yin, J. H. We report magnetism in carbon doped ZnO. Our first-principles calculations based on density functional theory predicted that...
Title: Late Holocene slip rate for the North Anatolian fault, Turkey, from cosmogenic 36Cl geochronology: Implications for the constancy of fault loading and strain release rates Authors: Özgür Kozaci, James Dolan, Robert Finkel, and Ross Hartleb Geomorphologic mapping and cosmogenic radio...
George Takei who played Sulu on Star Trek now has his name on an asteroid. The asteroid formerly known as 1994 GT9, is located between Mars and Jupiter, and has been renamed 7307 Takei in honour of the actor. The asteroid was discovered by two Japanese astronomers, Y. Shimizu, T. Urata in April, 1994....
This Envisat satellite image shows an ice-free Foxe Basin a shallow extension of the Atlantic Ocean located in the Canadian territory of Nunavut. Foxe Basin remains ice-covered for most of the year, with landfast ice (sea ice that remains attached to the coast) dominating in the north and pack ice (...
Title: VLA and XMM-Newton observations of the SNR W41/TeV Gamma-ray source HESS J1834-087
Authors: W.W. Tian, Z. Li, D.A. Leahy, Q.D. Wang
(revised v2)
The recently discovered extended TeV source HESS J1834-087 is associated with both a diffuse X-ray enhancement and a m...
This panel of composite images shows part of the unfolding drama of the last stages of the evolution of sun-like stars. Dynamic elongated clouds envelop bubbles of multimillion degree gas produced by high-velocity winds from dying stars. In these images, Chandra's X-ray data are shown in blue, wh...
Reginald Turnill, former BBC Space Correspondent and winner of the Arthur C Clarke Lifetime Achievement Award 2006, is to give an open lecture at the University of Kent on Wednesday 23 May. Titled 50 years: Russias Sputnik-1 to Apollo and the Space Shuttle, his lecture will take place at 6pm in the Br...
Title: Ruthenium and hafnium abundances in giant and dwarf barium stars Authors: D. M. Allen and G. F. Porto de Mello Aims. We present abundances for Ru and Hf, compare them to abundances of other heavy elements, and discuss the problems found in determining Ru and Hf abundances with laboratory gf-...
Title: The pre-cataclysmic variable, LTT 560 Authors: C. Tappert, B. T. Gänsicke, L. Schmidtobreick, A. Aungwerojwit, R. E. Mennickent, and D. Koester Aims. System parameters of the object LTT 560 are determined in order to clarify its nature and evolutionary status. Methods. We apply time-s...
With atoms and molecules in a gas moving at thousands of kilometres per hour, physicists have long sought a way to slow them down to a few kilometres per hour to trap them. A paper, published today in the Institute of Physics New Journal of Physics, demonstrates how a group of physicists from The Univer...
Turin capital of astronomy. The historic and cultural patrimony of one of the most important centres of planets, stars and galaxies study, has been opened to public, who can follow the researches and makes travels across the universe. The new astronomical park "Infini.to" of Pino Tori...
Hundreds of images snapped by the Hubble Space Telescope have been woven together to create a rich tapestry of thousands of galaxies. Astronomers created the panoramic view as part of a five-year project called AEGIS (All-wavelength Extended Groth strip International Survey). Eight of the worl...
There has been an Observatory associated with Glasgow University since 1757, and we presently occupy two sites. The main observatory ('Acre Road') is close to the Garscube Estate on the outskirts of the city. Our outstation ('Cochno', housing the big 20 inch Grubb Parsons telescope) is located fu...
Title: A refined analysis of the remarkable Bp star HR 6000 Authors: F. Castelli, S. Hubrig UVES spectra of the very young (~10^7 years) peculiar B-type star HR 6000 were analysed in the near-UV and visual spectral regions (3050-9460 A) with the aim to extend to other spectral ranges the study made pr...
