SPICA is the next generation infrared astronomy mission and SAFARI is an instrument on this 3.2m diameter space telescope. Currently, the European and Japanese Space Agencies study the feasibility of this mission, which plans to operate in the 20-210 um wavelength range and on an actively cooled primary mirror at a temperature of 6 Kelvin (-267 Celsius). SPICA will be about two orders of magnitude more sensitive than HERSCHEL. SAFARI is one of the three instruments discussed for the SPICA payload, an imaging Fourier-transform spectrometer employing ultra-sensitive TES bolometers. These bolometers are superconducting at low temperatures and have a large quantum efficiency. The instrument will be built by a European consortium. Oliver Krause will give us an overview of the current status of the project and discuss its science case and the potential contributions from MPIA to the SAFARI instrument.

The observation sequence is compounded from given templates. I.e. the acquisition of an object, the setup of the instrument as well as the sequence of exposures. Than, the observation at the telescope is more or less fully automatic and after a sequence of exposures is finished the data analysis starts also fully automatically.[[BR]][[BR]]Markus Feldt and Aleksei Pavlov will explain to us the data flow from the idea which the astronomer has in mind, down to the final planet detection. The focus will be on the detection, which is done with help of the delivered pipeline. They will shortly explain all the details of each processing step and intermediate analysis. Don't miss this talk if you want to be sure, that the outcome of your observation is not just an artifact.[[BR]][[BR]]Talk: German[[BR]]Slides: English[[BR]]Questions: German, English || |
