Institut für Astronomie & Astrophysik

Advanced Labwork in Astronomy and Astrophysics

The specialized course in Astronomy and Astrophysics offers an advanced labwork. The experiments will take place at section Astronomy (Sand 1) or at section Computational Physics (Auf der Morgenstelle 10).

ILIAS course: https://ovidius.uni-tuebingen.de/ilias3/goto.php?target=crs_1455182&client_id=pr02

SS 2018

In SS 2018 the labwork will be held as block during semester break from 30.07. - 10.08.2018 (Mo, We, Fr 9:00-18:00). If there should occur overlaps with other courses, single experiments might be shifted to later dates in agreement with the corresponding tutor.
Preparatory meeting (arrangement of groups, discussion of possible scheduling conflicts): Tu. 24.07.2018, 11:00 Uhr, Astronomy, Sand 1, room A 210 (orientation map, room map)

If someone will not be able to attend the preparatory meeting, the person is asked to register in advance by e-mail to Jürgen Barnstedt (or by Ilias, see below). There will be then an individual date arranged.

WS 2018/19

In WS 2018/19 the labwork will be held as block during semester break from 11.02. - 22.02.2019 (Mo, We, Fr 9:00-18:00). If there should occur overlaps with other courses, single experiments might be shifted to later dates in agreement with the corresponding tutor.
Preparatory meeting (arrangement of groups, discussion of possible scheduling conflicts): presumably Tu. 05.02.2019, 11:00 Uhr, Astronomy, Sand 1, room A 210 (orientation map, room map)

Organization

The experiments

  1. X-ray--CCD (Astronomy, Thomas Schanz room A142, meeting place room A112)
    Estimation of properties of a pn-CCD in the lab, analysis of measurements with the X-ray satellite XMM-Newton. (experiment instructions (german), PDF, 24.3 MB; poster (outdated), poster of the eRosita project).
  2. MCP detectors (Astronomy, Jürgen Barnstedt room A121, meeting place room A121)
    Using the micro channel plate detector of the ORFEUS echelle spectrometer the working principle and the properties of such detectors will be analyzed. experiment instructions, PDF, 4,5 MB; poster)
  3. Instruments of the gamma astronomy - RMC (Astronomy, Gerd Pühlhofer room A218, meeting place in front of room A110)
    Laboratory measurements with an imaging Rotating Modulation Collimator (RMC) by using radioactive sources. (experiment instructions (german), PDF, 5.7 MB; poster) - Note: As the expriment will take place in the basement, it is advisable to wear warm clothing, even in midsummer!
  4. Digital electronics for X-ray and gamma detectors (Astronomy, Chris Tenzer room A107, meeting place in front of room A107)
    Setup of a data aquisition electronics by means of programmable electronic components - FPGAs. (experiment instructions, PDF, 11.7 MB) - Note: As the expriment will take place in the basement, it is advisable to wear warm clothing, even in midsummer!
  5. Photometry and spectroscopy (Astronomy, Thomas Rauch room A211, meeting place room A211)
    Solar and stellar spectroscopy and color-brightness-diagrams. (experiment instructions), PDF, 5.8 MB; poster)
  6. Radio astronomy (Astronomy, Victor Doroshenko room A219, meeting place room A105)
    Measuring of the milky way by means of the 21cm radio emission of hydrogen, generation of a rotation curve and of a map of our milky way. (experiment instructions (german), PDF, 1.6 MB)
  7. Chaos in the planetary system (Computational Physics, Christoph Schäfer room C10 A11, (Willy Kley room C10 A45), meeting place C10 A11)
    In the classical N body problem the trajectories of N point masses in their common gravitational field are estimated. In this experiment, different numerical schemes for the solution of ordinary differential equations (ODEs) will be implemented and tested on the application to the integration of these trajectories. (web page of this experiment; poster)
  8. Classical experiments of Astronomy: Pulsars and rotation of Mercury (Astronomy, N.N.)
    This experiment is not offered in this semester. (experiment description (german), PDF 790 KB)

Each participant has to carry out 5 experiments. The exact arrangement into groups (usually 2 persons per group) and the scheduling of the experiments will be done during the preparatory meeting.

The posters of the experiments were presented during a labwork leader meeting held in Tübingen in September 2008.
