    4747|| '''03.06.2016''' || '''Thales Gutcke''' || '''What do galaxies consist of? State-of-the-art simulations of galaxy formation'''[[BR]][[BR]]In this talk, Thales Gutcke will give a brief overview of the present-day knowledge of galaxy formation. With a focus on the simulation methods themselves, she will introduce techniques like N-body and hydrodynamic calculations. The work is coupled to the central question of her PhD thesis: What do galaxies consist of? In this context, the talk will give some insight related to the "circum-galactic medium”, i.e. the nearly invisible gas far away from the stars within a galaxy[[BR]][[BR]]Presentation: German                  [[BR]][https://svn.mpia.de/trac/gulli/att/raw-attachment/wiki/AlteVortraege2016S1/2016-06-03_GalaxySimu.pdf Slides: English][[BR]]Questions: German, English ||
    48 || '''10.06.2016''' || '''Markus Feldt''' || '''METIS - Future perspective and current status'''[[BR]][[BR]]METIS  is one of the three, currently being developed first-light-instruments for the giant European telescope E-ELT. As camera and spectrograph for the mid-infrared wavelength range, it will yield astronomical data with an unprecedented richness of detail. The prime science case, which drives the instrument's specification, is the observation of dust disks around young stars and of those ones hosting exo-planets. But also in other fields, METIS will provide ground-breaking results.  [[BR]][[BR]]MPIA is the second largest contributor in the METIS consortium, which is led by NOVA in the Netherlands. We are responsible for the two imaging cameras and the wavefront sensor. The ambitious schedule aims for a delivery of the instrument to ESO in the year 2025.[[BR]][[BR]]          After the PI, Bernhard Brandl, gave a first overview exactly one year ago in the !AstroTechTalk, Markus Feldt will focus today a bit more on planets and disks and even stronger on the MPIA work packages and the currently running manpower discussions.[[BR]][[BR]]Presentation: German                  [[BR]][https://svn.mpia.de/trac/gulli/att/raw-attachment/wiki/AlteVortraege2016S1/2016-06-10_METIS_Update.pdf Slides: English][[BR]]Questions: German, English ||

    4949|| '''17.06.2016''' || '''Florian Schindler   [[BR]](Dr. Johannes Heidenhain GmbH)''' || '''High-precision angular gauges for telescopes'''[[BR]][[BR]]Since years, our instrumentation projects make use of the optical linear and angular encoders of the company Heidenhain from Upper Bavaria. For instance, this is currently the case for the De-Rotator in the MICADO project for the E-ELT. In this talk the company introduces itself and describes in particular the astronomical application of its optical sensors.[[BR]][[BR]]The following topics are handled in detail:[[BR]]- Overview of the company Heidenhain[[BR]]- Angular gauges for telescopes[[BR]]- Optical scanning principle in angular gauges[[BR]]- Accuracy and resolution of angular gauges in telescopes[[BR]]- Examples of telescopes making use of the Heidenhain sensors[[BR]][[BR]]Presentation: German                  [[BR]][https://svn.mpia.de/trac/gulli/att/raw-attachment/wiki/AlteVortraege2016S1/2016-06-17_Heidenhain.pdf Slides: English][[BR]]Questions: German, English ||
