	Contents:	Nobel prize winning phenomena: Their influence on modern quantum physics In this seminar we want to shed light on the interconnection of selected Nobel prize winning findings and their influence on modern day research, with topics broadly connected to the field of quantum physics. We especially want to point out developments that took place over decades, with multiple intermediate breakthrough results, showing the evolution of a research field over time. One prominet example here is superfluidity, where the first observation (Nobel prize 1013) was followed by a theoretical explanation (Nobel price 1962), which then was carried on to new platforms (Nobel price 2001) and more refined microscopic theories (Nobel price 2003). Participants are expected to present the topic of their choice in a 30 minute talk, which is followed by a scientific discussion. In the introductory meeting, the detailed expectations are given, and each participant will be guided by a tutor during the preparation of the talk.

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.
	Comments:	Please check eCampus for up-to-date information on the format (in-person, hybrid, online, ...).
astro847	Optical Observations Fr 11-13, Raum 0.012, AIfA Exercises: Mo 9
	Instructor(s):	T. Schrabback, M. Tewes
	Prerequisites:	Astronomy introduction classes
	Contents:	Optical CCD and near infrared imaging, conducting and planning observing runs, 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 rooftop.
	Literature:	Provided upon registration.
	Comments:	The class has a strong focus on hands-on observations and data analysis in Python. 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 observations).
astro849	Multiwavelength observations of galaxy clusters Mo 16-17:30, Raum 0.008, AIfA Exercises: 1 hr. by appointment
	Instructor(s):	T. Reiprich, F. Pacaud
	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.
