High Energy Astrophysics:
The Solar Intensity X-ray and particle Spectrometer (SIXS), which will be flown with ESA’s BepiColombo mission to Mercury by the end of next decade. The long wings (span 55 cm) are part of radiator needed for cooling the instrument in the very hot environment at Mercury’s orbit.
Interstellar medium, star formation and magnetic activity of stars:
Part of a filament in the Corona Australis molecular cloud. The image is a composite of J-, H-, and K-band near-infrared observations that were made with the SOFI instrument on ESO’s NTT telescope.
The observations confirmed that the cloud’s surface brightness is caused by scattered light and that this signal can be used for accurate mapping of cloud structure. The J-, H-, and K-band intensities are coded with blue, green, and red colours. The gradual saturation of the near-infrared bands is visible as a change of colour. In the centre of the filament, the shorter wavelengths are strongly saturated and the red colour
Planetary System Research:
Observed topocentric positions of moving objects and selected, realistic paths linking the positions. The observations were made in 2004 with the European Southern Observatory’s Very Large Telescope (VLT) and the Canada-France-Hawaii Telescope (CFHT). The VLT observations were made on five consecutive nights (January 20-24; red, green, blue, magenta, and aqua), whereas the CFHT observations were made on January 22 (yellow) and January 30 (black). Each dot correspond to the first observation of an in-trinsically correctly linked set of observations obtained at a single telescope during a single night.
Examples of porous random media made of spherical particles with fractional-Brownian-motion boundary surfaces. The packing of the media is carried out using an optimized Monte-Carlo dropping method and a realistic particle size distribution. For the two example media shown, the volume densities are about 30%, but more tightly packed media can be simulated as well, up to volume densities of about 75%.
