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)

 

NEW: It is now possible to register online by ILIAS:

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 (experiment instructions (german), PDF, 24.3 MB; poster (outdated), poster of the eRosita project).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 (german), PDF, 5.8 MB; poster)
  6. Radio astronomy (Astronomy, Daniel Gottschall room A105, 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.

Prerequisites

  • Successful participation in the basic module "Astronomy and Astrophysics" (study path Bachelor) or student of Master of Science Astro and Particle Physics.
  • Basic knowledge in programming:
    For the experiments carried out by Computational Physics it is expected, that the participants are able to write small programs by their own, e.g. in C or FORTRAN. Online tutorials are available on the web page Hints for the programming experiments. In case of questions or problems W. Kley resp. C. Schäfer will give some help.
    The analysis of the Astronomy experiments is done ususally with the programming and interpreter language IDL. The required steps are described in detail in the corresponding experiment instructions.
  • For the experiment MCP detectors knowledge of Excel is helpful, but not really required.
  • It is expected that the experiment instructions are read and understood by the date of the experiment. This will be checked by an oral attestation prior to the beginning of the experiment. Some experiment instructions contain excercises and questions in the theroretical part, which should be solved and presented during this attestation.
  • The experiment instructions of MCP detectors contains at the end a chapter with general Hints for writing a protocol. It is obligatory to read these hints prior to starting the labwork and to subsequently follow these hints!
  • The programming experiments will take place in the computer room of the Theoretical Physics (CIP-Pool, Morgenstelle D2A38, login with the usual university account).
