Signatur von Stossfronten in verschmelzenden und aktiven Galaxien. Optische/UV- und Roentgenbeobachtungen
(2010-08-16)Merging galaxy system Markarian 266 (also NGC 5256) is a double nucleus system. This system lies at a distance of 115 Mpc. The two nuclei are thought to comprise a low-ionization nuclear ... -
Spectropolarimetry of sunspot penumbrae
(2007-01-03)This work presents a detailed study of the fine structure of sunspot penumbrae by means of observations with high spatial resolution and forward modelling. The use of image reconstruction ... -
Simulationsrechnungen anisoplanatischer Übertragungsfunktionen für solare Adaptive Optik
(2006-11-06)With the Adaptive Optics (AO) System KAOS (Kiepenheuer Adaptive Optics System), installed at the Vacuum-Tower-Telescope (VTT) on Tenerife (Spain) and developed at the Kiepenheuer-Institut ... -
Magnetic flux emergence in the solar photosphere
(2006-06-29)The most prominent magnetic structures on the surface of the Sun are bipolar active regions. These magnetic complexes are comprised of a hierarchy of magnetic structures of different sizes, ... -
Kinetische Plasmaprozesse und Welle-Teilchen-Wechselwirkung von Ionen im schnellen Sonnenwind
(2006-04-07)Many important properties of the fast solar wind may only be explained by plasma waves that interact with solar-wind particles. The quasi-linear approximation to this interaction, which is ... -
A feasibility study about the use of vector tomography for the reconstruction of the coronal magnetic field
(2006-03-20)The magnetic field contains the dominant energy per unit volume in the solar corona and therefore plays an important role in most coronal phenomena. But until now, no direct measurement of ... -
Arrival times in quantum mechanics: Operational and quantum optical approaches
(2005-07-29)The theoretical analysis of time observables in quantum mechanics has been controversial and is still subject to debate. In the present work, a measurement-based approach to quantum arrival ... -
Molecular dynamics of clathrin proteins at endocytic sites studied with evanescent-wave microscopy
(2004-10-04)Clathrin (consisting of a light chain and a heavy chain subunit) is a triskelion-shaped molecule that self-assembles into polyhedral lattices on cellular membranes. It has a pivotal role ... -
Three-dimensional simulations of magneto-convection in the solar photosphere
(2004-03-22)The interaction between convective flows and magnetic fields in the solar photosphere and uppermost layers of the convection zone is crucial for many aspects of solar activity and plays an ... -
Equatorial Coronal Holes and Their Relation to the High-Speed Solar Wind Streams
(2003-11-18)The heating of the solar corona and the origin and acceleration of the solar wind are among the important unsolved problems of space plasma and solar physics. Coronal holes (CHs) have been ... -
Untersuchung der Wechselwirkung von Magnetfeldkonzentrationen und konvektiven Stroemungen mit dem Strahlungsfeld in der Photosphaere der Sonne
(2002-04-30)The development of small scale magnetic flux concentrations, its dynamical interaction with convective flows is investigated through twodimensional simulations of the solar magnetoconvektion ... -
Phasenaufgelöste Spektrophotometrie des magnetischen kataklysmischen Veränderlichen EX Hya
(2001-01-03)This thesis describes time-resolved observations of the eclipsing intermediate polar (IP) EX Hya at X-ray, UV, optical and near infrared wavelengths. IPs form a subclass of the cataclysmic ...
