Circumplanetary dust dynamics
(Univ. Potsdam, 2007)
Our Solar system contains a large amount of dust, containing valuable information about our close cosmic environment. If created in a planet's system, the particles stay predominantly in its vicinity and can form extended ...
Accretion and emission close to supermassive black holes in quasars and AGN
(Univ. Hamburg, 2006)
With the last generation of X-ray satellites, such as XMM-Newton and Chandra, our knowledge about the X-ray properties of Active Galactic Nuclei (AGN) has greatly improved. Detailed spectroscopy and long-term observations ...
Kinematik und Dynamik neogener Deformationsprozesse des südzentralchilenischen Subduktionssystems, nördlichste Patagonische Anden (37° - 40° S)
(Univ. Hamburg, 2003)
Die dynamische Entwicklung des neotektonisch und vulkanisch aktiven südchilenischen Plattenrandes wird durch die schiefe Subduktion der ozeanischen Nazca Platte unter den südamerikanischen Kontinent gesteuert. Die Deformationen ...
X-ray and optical properties of X-ray luminous active galactic nuclei
(Univ. Potsdam, 2008)
Giacconi et al. (1962) discovered a diffuse cosmic X-ray background with rocket experiments when they searched for lunar X-ray emission. Later satellite missions found a spectral peak in the cosmic X-ray background at ~30 ...
Stabilitätsuntersuchungen an Asteroidenbahnen in ausgewählten Bahnresonanzen des Edgeworth-Kuiper-Gürtels
(Univ. Dresden, 2008)
This dissertation presents a comprehensive description of the stability of asteroid orbits in the Edgeworth-Kuiper belt taking the 3:5, 4:7 and 1:2 mean motion resonance with Neptune as example. Further emphasis is given ...
Groundwater exploration and management using Geophysics: northern region of Ghana
(Univ. Cottbus, 2006)
Groundwater has been identified as the best source for rural water supply in most rural communities in the Northern region of Ghana because it eliminates the problems of water borne diseases which have affected communities ...
The Levantine Basin
(Univ. Hamburg, 2006)
The Levantine Basin - a seismic investigation of the crustal structure and the evolution of the Messinian evaporites ABSTRACT This work presents an analysis of the crustal structure of the Levantine Basin, based on refraction ...
The role of binary stars in searches for extrasolar planets by microlensing and astrometry
(Univ. Potsdam, 2006)
Bei von Sternen verursachten Mikrolinsen-Ereignissen beobachtet man meist symmetrische Lichtkurven einer einzelnen Linse oder asymmetrische Lichtkurven (oftmals mit Kaustik-Crossing), die durch Doppel-Linsen hervorgerufen ...
Anwendung der dielektrischen Erwärmung mit Radiowellen in der Umwelttechnik
(TU Freiberg, 2006)
