physics712 Advanced Electronics and Signal Processing
Tu 9, We 10-12, HS, HISKP
  Instructor(s): P.-D. Eversheim, H. Krüger
  Prerequisites: Mandatory: Electronics lab course
Recommended: Electronics for Physicists
  Contents: This lecture addresses basic concepts, techniques, and electronics necessary to identify and handle relevant events in complex data streams or detector arrays, respectively. Advantages and limits of analogue and digital electronics will be explained and can be experienced by means of three major topics.

  1. Hands on experiment at the Bonn Isochronous Cyclotron: Set up electronics to identify whether an ejectile was a Proton, Deuteron, 3He or α particle. Set up electronics to discriminate Neutrons from Gammas by pulse shape.

  2. Understand the potential of Digital Signal Processors (DSP). The hard- and software aspects are discussed and demonstrated by means of an experimental DSP-board. The demonstrations will focus on digital signal conditioning and filtering.

  3. Hands on course in Field Programmable Gate Array (FPGA) programming.

  Comments: The experiments at the Bonn Isochronous Cyclotron will take place on 4 afternoons
physics716  Statistical Methods of Data Analysis
Fr 10-12, HS, IAP
  Instructor(s): K. Desch
  Prerequisites: Some prior basic knowledge of particle physics would be helpful, but is not absolutely necessary.
  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.

In the beginning of the semester, I will introduce a number of general measurement schemes. Afterwards, I will discuss examples from both fundamental research (e.g. optical clocks, Hydrogen spectroscopy, and searches for physics beyond the standard model) and applications (NMR, magnetometry, gyroscopes).

domains (radio astronomy, infrared, optical, etc.) will also be discussed.
astro8402 X-ray astronomy
Fr 13-15, Raum 0.012, AIfA
Exercises: 1 hr. by appointment
  Instructor(s): T. Reiprich
  Prerequisites: Introductory astronomy course.
  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. This includes, e.g., comets and planets in our solar
system; Galactic systems like extrasolar planets, cool and hot stars, remnants of exploded stars, isolated
white dwarfs and neutron stars, cataclysmic variables, close binaries with neutron stars and black holes, hot
interstellar medium, and the Galactic center region; extragalactic X-ray sources like spiral and elliptical
galaxies, galaxy clusters, intergalactic medium, and active galactic nuclei, i.e., supermassive black holes
lurking in the centres of galaxies. The X-ray emission and absorption processes as well as current and future
space-based instruments used to carry out such observations will be described, including the eROSITA space
telescope to be launched in 2019. In the accompanying lab sessions, the participants will learn how to
download, reduce, and analyze professional X-ray data from a satellite observatory.
  Literature: A script of the lecture notes will be provided.

detectors, data reduction, catalogue handling, astrometry, coordinate systems,
photometry, spectroscopy, photometric redshifts, basic weak lensing data
analysis, current surveys, ground-based data versus Hubble Space Telescope
observations, how to write observing proposals.

Practical experience is gained by obtaining and analysing multi-filter CCD
imaging observations of galaxy clusters using the 50cm telescope on the AIfA
  Literature: Provided upon registration.
  Comments: The class has a strong focus on hands-on observations and data analysis. It
should be particularly useful for students who consider conducting a master's
thesis project which involves the analysis of optical imaging data from
professional telescopes (e.g. wide-field imaging data or Hubble Space Telescope
astro849 Multiwavelength observations of galaxy clusters
Mo 15.30-17, Raum 0.008, AIfA
Exercises: 1 hr. by appointment
  Instructor(s): T. Reiprich
  Prerequisites: Introductory astronomy course.
  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 intracluster 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, active
supermassive black holes, cluster weighing methods, Sunyaev-Zeldovich effect, gravitational lensing, radio
halos and relics, tailed radio galaxies, and the most energetic events in the Universe since the big bang:
cluster mergers.
  Literature: Lecture script and references therein.
astro851 Stellar and solar coronae
Th 13-15:15, Raum 0.01, MPIfR
Exercises: 1 hr. by appointment
  Instructor(s): M. Massi
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.
  Literature: The Solar Corona.
