Lab course Astrophysics - Master Astrophysics Modul 751

P Rainer HainichTime and place by arrangement
S/1. Wo. Rainer Hainich/Veronika SchaffenrothDienstag, 16.15-17.45 UhrRaum 2.28.2.011

Content:

The subject of this course is to perform and analyze astronomical observations. The observations will be carried out with the student's observatory, located on the roof of the Institute of Physics and Astronomy, and the "Einsteinturm", a solar observatory based on the Telegraph Hill close to the city center. Throughout this course, the students will e.g. derive the age of star clusters from CCD photometry, determine spectral types with the help of stellar spectroscopy, and estimate the rotational period of the Sun and the magnetic field strengths in sunspots by means of very high resolution spectroscopy. The associated seminar not only imparts the theoretical knowledge that is necessary to perform and quantitatively analyze the observations but also serves as a stage to present and discuss the obtained results.mi

S 2. WoVarsha Ramachandran/Wolf-Rainer Hamann*Donnerstag, 12.15-13.45 Uhr Raum 2.28.2.011

Inhalt:
Only since the advent of ultraviolet telescopes in the 1970s it became known that most of the stars give off mass to their environment. Especially massive stars can accelerate huge amounts of matter within less than an hour to velocities up to one percent of the speed of light. The mass loss has decisive influence on the life and death of stars, i.e. on their evolution. Currently, the interest is focused e.g. on the progenitors of massive black holes, since the merging events of such objects in close binary systems have been recently observed as source of gravitational waves. The matter that is returned by a star into the interstellar space is available for the formation of new stars. Stellar winds, together with explosions, are thus the essential players in the cosmic circuit of matter, driving the chemical evolution of the cosmos. This lecture is devoted to theoretical as well as observational aspects of stellar winds. Depending on the interests of the students, the lecture might be complemented by some exercises with the computer, e.g. for developing small numerical simulations or analyzing observational data.

Inhalt:
Observations in the X-ray band of electromagnetic spectrum are pivotal to study fundamental astrophysical processes. Among these processes is the formation of large structures in the Universe; the birth and growth of black holes; stellar activity and its ibfluence on the origin of life. In the last decade a major step forward in our studies of X-ray sources was made, thanks to powerful space X-ray telescopes (XMM-Newton and Chandra). The goal of this lecture course is to provide a solid background in X-ray instrumentation and physics of cosmic plasmas. On this basis, we will combine recent theories and observations, and review what is known about various types of cosmic X-ray sources across all astrophysical scales, from planets to galaxy clusters. The course is based on current research literature and provides insight in the methodology of modern astrophysics.

Inhalt:
Quasars, or active black holes, are among the most powerful and energetic objects known in the universe. Their enormous luminosity allows us to observe their light at extreme distances, spanning large parts of the visible universe. On its way to Earth their light interacts with all the gaseous matter along the line of sight. We detect those gases by their characteristic absorption signatures in the quasar spectrum and can derive the redshift and chemical composition of the absorbing clouds. This lecture teaches the required fundamentals of absorption spectroscopy and applies the gained knowledge to actual data to become accustomed to real quasar absorption spectra. Quasars and their spectra provide an important window to the distant and early universe and enable us to study physics at a billion light years distance.

For Bachelor Science Physics students is this lecture (with essay) and the course (Astronomie im Praktikum) part of modul 532


Inhalt:
Determining distances of astronomical objects is a fundamental challenge in astrophysics. In part II of this two-semester course the methods to determine extragalactic distances are presented. Starting with the distance of the Large Magellanic Cloud which is an important anchor point for distance calibrations, we explore the so-called extragalactic distance ladder. We will discuss methods like measuring distances using Cepheids, the tip of the Red Giant branch, type Ia Supernovae, as well as distance indicators that consider inherent properties of galaxies. Finally, recent progress in estimating the Hubble constant will be discussed. Each method will be applied practically by the students themselves. The lecture is independent of part I of this course, which has focused on explicitely galactic distances.

S 2.Wo.Kasper Borello Schmidt/Lutz Wisotzki*Mittwoch, 8.15-9.45 Uhr Raum 2.28.2.011

Inhalt:
The theory of gravitational lensing (GL) is one of the three fundamental observational consequences of Einsteins theory of general relativity. GL describes how rays of light are bent by massive astronomical objects like stars, galaxies and galaxy clusters. This results in magnification and potentially in multiple images on the sky of lensed sources. These unique consequences of GL have been instrumental and of growing importance in modern extragalactic astronomy. Laying out the theoretical framework describing the principles and consequences of GL, this course will focus on recent studies enabled by GL and on scientific applications, where GL plays a crucial role. These include galaxy (cluster) mass determination, spatially resolved mapping of low-mass galaxies in the distant Universe, determining the expansion rate of the Universe, and detecting planets around other stars.

S 2.Wo.Umberto Maio/Christoph Pfrommer*Mittwoch, 9.15-10.00 Uhr Raum 2.28.2.011

Inhalt:
The birth and evolution of cosmic structure is one of the most outstanding problems in Astrophysics. While the basic processes of gas condensation and fragmentation have been qualitatively addressed in the past, a full understanding of such issues involves a number of physical and chemical processes that are far from from being completely solved. Furthermore, currently planned and upcoming international space missions will collect huge amounts of data to shed light on the formation of the first stars and galaxies. In this lecture series, we will initially outline the simple approaches to gas condensation and then we will show how environmental properties of the collapsing material (such as molecular content, heavy elements, radiation, feedback effects) influence the resulting stellar mass function, star formation rate, as well as the black-hole origins over cosmological epochs. The evolution of the formed baryonic structures will rely on the complex interplay among mechanical chemical and radiative processes that will be addressed during the lectures.
