v109 v110 51 51 || '''26.06.2015''' || '''Knud Jahnke''' || '''EUCLID'''[[BR]][[BR]]Do you know what dark energy and dark matter is? But they make 95% of the energy in the universe! EUCLID is an M-class mission of ESA launching 2020, with the goal to change our understanding of this dark side of the universe. The satellite has two instruments aboard. One is a visible imager (VIS) and the other is a near infrared spectrometer and photometer (NISP). MPIA builds two major components of NISP. The first component is the calibration source of NISP and the second are the infrared filters of the instrument. But our institute is also involved in the calibration of the mission, simulation of the NISP instrument[[BR]] and we supply the mission with the photometry instrument scientist.[[BR]][[BR]] Knud Jahnke will present an overview of EUCLID and NISP and tell us the current status of the NISP development in house and over all.[[BR]][[BR]][[BR]]Talk: German[[BR]][https://svn.mpia.de/trac/gulli/att/raw-attachment/wiki/WikiStart/2015-06-12_METIS.pdf Slides: English][[BR]]Questions: German, English || 52 52 || '''03.07.2015''' || '''Reinhard Mundt''' || '''CARMENES''' [[BR]][[BR]]The talk will consist of two main parts. The first part I will give an overview over the whole CARMENES-Project. CARMENES consists of two high-resolution 'echelle spectrographs (R=82000) for the search of extrasolar planets around nearby low-mass stars. One spectrograph covers the optical wavelength range (0.55-0.95 micron) and the other one the NIR wavelength range (1.0 - 1.7 micron). In the second part of the talk I will report about the detector cryostat for the NIR spectrograph, which is the major contribution of the MPIA to this project. It is equipped with a mosaic of two Hawaii 2RG detectors, which will be operated at about 85 K. This detector cryostat has been recently sent to our partner institute (IAA, Granada), where it will integrated soon for the first time in the 140 K cold NIR spectrograph.

A long and iterative process of design, manufacture, assembly, coding, alignment and verification will then be accomplished with an intense involvement of all technical departments at MPIA. During the last months the work was focused on the interplay of all systems as one instrument, besides the completion of a multitude of open details.[[BR]][[BR]]Thomas Bertram will explain, in which way the complex instrument was integrated and tested, what LINC-NIRVANA is able to do, what it yet not can do and how the story continues at the telescope.

Nearly all aspects of astronomy are therefore in the end reducible to the exegesis, i.e. interpretation of light from the cosmos. There are good reasons to observe many celestial directions with steadily increasing resolution and sensitivity and at many different wavelengths. [[BR]][[BR]]Hans-Walter Rix will sketch, which technical and scientific possibilities emerge for observations with highest image quality using today's and future observatories.
