Search for tidal streams in disk and halo
(Univ. Bochum, 2008)
This work deals with the search for substructures in four nearby galaxies (NGC 300, NGC 7793, M 33, M 83) in which it is possible to resolve single stars in their outer parts.The search is based on the photometry of wide ...
Comprehensive evaluation of an improved large‐scale multi‐site weather generator for Germany
(
- International Journal of Climatology
, 2021-04-07)
In this work, we present a comprehensive evaluation of a stochastic multi‐site, multi‐variate weather generator at the scale of entire Germany and parts of the neighbouring countries covering the major German river basins ...
Yield Function of the DOSimetry TELescope Count and Dose Rates Aboard the International Space Station
(
- Space Weather
, 2021-04-28)
The Earth is constantly hit by energetic particles originating from galactic sources. The flux of these particles is altered by the magnetized solar wind in the heliosphere and the Earth's magnetic field. For this reason, ...
Three-dimensional finite element modeling of slip rate variations on faults caused by glacial interglacial changes in ice and water volumes
(Univ. Bochum, 2008)
Paläoseismologische Daten lassen vermuten, dass viele aktive Störungen in unterschiedlichen tektonischen Settings eine Veränderung in der Bewegungsrate auf der Störung kurz nach dem Ende des letzten glazialen Maximums ...
Near- and mid-infrared studies of the galactic center and Sagittarius A*
(Univ. Köln, 2007)
The focus of this thesis lies on the analysis and interpretation of near- and mid-infrared images of the Galactic center, with a view to improving the understanding of this region, especially at longer wavelengths. Multi-band ...
On the Limitations and Implications of Modeling Heat Transport in Porous Aquifers by Assuming Local Thermal Equilibrium
(
- Water Resources Research
, 2020)
Heat transport in natural porous media, such as aquifers or streambeds, is generally modeled assuming local thermal equilibrium (LTE) between the fluid and solid phases. Yet, the mathematical and hydrogeological conditions ...
Interdecadal Pacific Oscillation Drives Enhanced Greenland Surface Temperature Variability During the Last Glacial Maximum
(
- Geophysical Research Letters
, 2020-12-04)
Stable oxygen isotope records from central Greenland suggest disproportionally large long‐term surface air temperature (SAT) variability during the Last Glacial Maximum (LGM) relative to preindustrial times. Large perturbations ...
Geoelektrisches Monitoring einer thermischen in situ-Grundwasser- und Bodensanierung
(Univ. Dresden,Techn. Univ., 2009)
Die vorliegende Arbeit entstand im Rahmen einer pilotmaßstäblichen Boden- und Grundwassersanierung am Industriestandort Hydrierwerk Zeitz. Auf dem Gelände einer ehemaligen Benzolproduktionsanlage wurden großflächige ...
Accretion, winds and jets
(Univ. Hamburg, 2009)
This thesis deals with the high-energy emission from young stellar objects, which are on the one hand still actively accreting from their disk, and on the other hand are no longer deeply obscured by their natal cloud. Stars ...
A contribution to characterizing and calibrating the pointing control system of the SOFIA telescope
(Univ. Stuttgart, 2009)
SOFIA, the Stratospheric Observatory for Infrared Astronomy, is an airborne observatory that will study the universe in the infrared spectrum. A Boeing 747-SP aircraft will carry a 2.5 m telescope designed to make sensitive ...
