physics716 Statistical Methods of Data Analysis
We 8-10, SR I, HISKP
  Instructor(s): P. Bechtle
  Prerequisites: Some prior knowledge of particle physics would be helpful.
  Contents: From the first lab. course that you take to the design and construction of an experiment; from the first simulations to the final analysis of the data from our experiment, the proper application of statistical methods is essential.

The aim of this course is to provide a foundation in statistical methods and to give some concrete examples of how the methods are applied to data analysis. Standard statistical distributions will be discussed and examples given of when they are expected to occur and how they are related.

Techniques for fitting data will be discussed. The treatment of systematic errors, as well as methods to combine results from different experiments which may have common error sources will also be covered.

The search for new physics, even when no signal is observed, allows limits to be placed on the size of possible effects. These can provide severe constraints on theoretical models. Methods for calculating upper limits taking into account several error sources will also be considered.

      physics774  Electronics for Physicists
      Mo 10-12, Th 9, SR I, HISKP
      Diplom: VANG, WPVANG
        Instructor(s): P.-D. Eversheim
        Prerequisites: Practical course in electronics
        Contents: One of the "classic" abilities of an experimentalist is to build those instruments himself he needs but can not get otherwise. In this context the knowledge of electronics - in view of the growing electronics aided acquisition and control of experiments - becomes a key skill of an
      experimentalist.
      The intention of this lecture is to enable the students by means of exemplary experiments to work out concepts to solutions for given problems. It will be shown that many of these solutions or concepts to solutions, respectively, are used in other fields of physics too (quantum mechanics, optics, mechanics, acoustics, . . .). At the end of this lecture, the student should:
      i) have an overview over the most common parts in electronics.
      ii) be concious about the problems of handling electronic parts and assemblies.
      iii) understand the concepts that allow an analysis and synthesis of the dynamic
      properties of systems.

      astro8402  X-ray astronomy
      Fr 13-15, Raum 0.012, AIfA
      Exercises: 1 hr. by appointment
        Instructor(s): T. Reiprich
        Prerequisites: Introductory courses on astronomy, atomic physics, and hydrodynamics would be useful.
        Contents: X-rays are emitted from regions where the Universe is hot and wild. The lecture will provide an overview
      of modern X-ray observations of all major X-ray sources, e.g., remnants of exploded stars, the vicinities
      of lightweight and supermassive black holes, and collisions of galaxy clusters -- the most massive
      objects in the Universe. The physical properties of X-ray radiation as well as current and future space-
      based instruments used to carry out such observations will be described. In the accompanying lab
      sessions, the participants will learn how to download, reduce, and analyze recent X-ray data from a
      satellite observatory.
        Literature: A bound script of the lecture notes will be provided.

      astro8403  Hydrodynamics and astrophysical magnetohydrodynamics
      Exercises: 1 hr. by appointment
      Mi 13:30-15, Raum 0.008, AIfA
        Instructor(s): J. Braithwaite
        Prerequisites: Vector calculus, thermodynamics
        Contents: The course covers all fundamental concepts of hydrodynamics, and is accessible for all physics students, not just astrophysicists. There is a bias towards scientific rather than engineering applications, i.e. a greater emphasis on e.g. stellar winds, and atmospheric waves and supernovae than on airflow over aeroplane wings, and more specifically on astro-, geo- and planetary physics. The topics covered are (in approximately this order): the hydrodynamics equations; basic concepts such as Bernoulli's equation, (in)compressible, sub- and supersonic flow, nozzles, stellar winds and vorticity; waves of a few different and relevant types, as well as associated instabilities of interest to astrophysicists and associated turbulence; viscosity, similarity flows and boundary layers; shocks; rotating fluid systems; and finally a brief introduction to magnetohydrodynamics, the study of electrically conducting fluids, including some astrophysical contexts such as the solar corona, jets and discs.
        Literature: Landau & Lifschitz "Hydrodynamics";
      Choudhuri "The physics of fluids and plasmas";
      Pedlosky "Geophysical fluid dynamics";
      Shore "Astrophysical hydrodynamics"
        Comments: The last part of the course introduces magnetohydrodynamics, whose applications lie mainly in astrophysics. If you basically know about fluid dynamics already but would like to learn something about MHD, you are more than welcome to attend the last ~2 lectures in the course as a "tourist" - they are designed to be stand alone, i.e. understandable if you didn't attend the other lectures. The first of the MHD lectures will probably be on 27th June, but check the webpage beforehand.

      astro849  Multiwavelength observations of galaxy clusters
      Mo 15.30-17, Raum 0.008, AIfA
      Exercises: 1 hr. by appointment
        Instructor(s): T. Reiprich, Y. Zhang
        Prerequisites: Introductory Astronomy lectures.
        Contents: Aims of the course:
      To introduce the students into the largest clearly defined structures in the Universe, clusters of galaxies.
      In modern astronomy, it has been realized that a full understanding of objects cannot be achieved by
      looking at just one waveband. Different phenomena become apparent only in certain wavebands, e.g.,
      the most massive visible component of galaxy clusters -- the intracuster gas -- cannot be detected with
      optical telescopes. Moreover, some phenomena, e.g., radio outbursts from supermassive black holes,
      influence others like the X-ray emission from the intracluster gas. In this course, the students will
      acquire a synoptic, multiwavelength view of galaxy groups and galaxy clusters.
      Contents of the course:
      The lecture covers galaxy cluster observations from all wavebands, radio through gamma-ray, and
      provides a comprehensive overview of the physical mechanisms at work. Specifically, the following
      topics will be covered: galaxies and their evolution, physics and chemistry of the hot intracluster gas,
      relativistic gas, and active supermassive black holes; cluster weighing methods, Sunyaev-Zeldovich
      effect, gravitational lensing, radio halos and relics, and the most energetic events in the Universe since
      the big bang: cluster mergers.

      astro851  Stellar and solar coronae
      Do 13-14:30, Raum 0.01, MPIfR
      Exercises: 1 hr. by appointment
        Instructor(s): M. Massi
        Prerequisites:  
        Contents: T Tauri (young stellar systems not yet in Main Sequence) and RS CVn systems (evolved stellar systems that already left the Main Sequence), although very diverse systems, have similar flare activities observed at radio and X-ray wavelengths.

      The flares in both systems are several orders of magnitude stronger than those of the Sun. The origin of this activity, defined "coronal activity", depends on the convective zone, the rotation, the formation and dissipation of magnetic fields. In general terms: This is a mechanism of the same type as on the Sun, but enforced by the binary nature of these systems.

      In these lectures we will explore a link between the amplification of initial magnetic fields by dynamo action in several rotating systems ( Sun, binary systems and accretion discs around black holes) and the release of magnetic energy into a corona where particles are accelerated.

      Together with the basic theory there will be as well illustrated the latest progress in the research on stellar coronal emission derived from recent space missions and high-resolution radio observations.

      6951  Seminar on scientific writing
      Mi 9-11, Raum 0.008, AIfA
        Instructor(s): F. Bertoldi, R. Izzard, U. Klein, A. Stolte
        Prerequisites: Some English language skills are required, as with all Masters research. (This course is not about learning English!)
        Contents: Good communication is the key to making yourself known in the scientific world. If you cannot write, and cannot write well, your papers will struggle to to make an impact - assuming they are published at all.
      Why do so many good scientists struggle to put their thoughts on to paper? This course aims to overcome that hurdle, to show that because you are a scientist you can think and write in a logical, clear and precise way. Most of the course is about how to structure your articles, but a sizeable fraction is also about style and the English language. Classes are mostly interactive with the emphasis on learning by doing.
