The VSA (Very Small Array) has made CMB observations in three different configurations, corresponding to different multipole order (l) ranges: compact for l=150-800 (Taylor et al. 2003, Cat. J/MNRAS/341/1066), extended for l=300-1500 (Dickinson et al. 2004MNRAS.353..732D) and super-extended for l=600-2500. The corresponding areas have been surveyed

The sulphur-containing proteinaceous amino acids l-cysteine, l-cystine and l-methionine were irradiated in the solid state to a dose of 3.2 MGy. This dose corresponds to that delivered by radionuclide decay in a timescale of 1.05 x 10(9) years to the organic matter buried at a depth > 20 m in comets and asteroids. The purity of the sulphur

A photometric method to detect planets orbiting around shortperiodic binary stars is presented. It is based on the detection of eclipse-signatures in the reflected light of circumbinary planets. Amplitudes of such 'reflected eclipses' will depend on the orbital configurations of binary and planet relative to the observer. Reflected eclipses will

Context. The transient X-ray source XMMU J004215.8+411924 within M 31 was found to be in outburst again in the 2010 May 27 Chandra observation. We present results from our four Chandra and seven Swift observations that covered this outburst. Aims: X-ray transient behaviour is generally caused by one of two things: mass accretion from a high mass
