The metagalactic UV background at z < 3
(Univ. Hamburg, 2005)The high ionization state of the intergalactic medium (IGM) is maintained by the metagalactic UV background radiation. This ionizing radiation field is supposed to be the integrated radiation of quasars and young star-forming ... -
The Mie representation for Mercury’s magnetic field
; ; ;
; ; ; (Earth, Planets and Space, 2021-03-08)
The parameterization of the magnetospheric field contribution, generated by currents flowing in the magnetosphere is of major importance for the analysis of Mercury’s internal magnetic field. Using a combination of the ... -
The Mie representation for Mercury’s magnetospheric currents
; ;; ; ; ; (Earth, Planets and Space, 2021-11-09)
Poloidal–toroidal magnetic field decomposition is a useful application of the Mie representation and the decomposition method enables us to determine the current density observationally and unambiguously in the local region ... -
The Mini Induced Magnetospheres at Mars
; ; ; ; ; (Geophysical Research Letters, 2023-02-08)
We report on observations made by the Mars Atmosphere and Volatile EvolutioN spacecraft at Mars, in the region of the ion plume. We observe that in some cases, when the number density of oxygen ions is comparable to the ... -
The narrow line region of active galaxies
(Univ. Bochum, 2005)This thesis presents an imaging and spectroscopic study of the narrow-line region (NLR) in active galactic nuclei (AGNs). We find a correlation between size and luminosity of the NLR with different slopes for type-1 and ... -
The near infrared activity of Sagittarius A*
(Univ. Köln, 2008)The meaning of my thesis was to obtain new insights about the supermassive Black Hole in the center of our Milky Way and its accretion flow. The non-thermal radio, X-ray, and near-infrared source Sagittarius A* (Sgr A*) ... -
The Norwegian-Greenland Sea, the Laschamps, and the Mono Lake Excursions Recorded in a Black Sea Sedimentary Sequence Spanning From 68.9 to 14.5 ka
; ; ; ; (Journal of Geophysical Research: Solid Earth, 2020)
A full-vector paleomagnetic record, comprising directional data and relative paleointensity (rPI), was derived from 16 sediment cores recovered from the southeastern Black Sea. The obtained data were used to create a stack ... -
The observed recent surface air temperature development across Svalbard and concurring footprints in local sea ice cover
; ; ; ; ; ; (International Journal of Climatology, 2020)
The Svalbard archipelago in the Arctic North Atlantic is experiencing rapid changes in the surface climate and sea ice distribution, with impacts for the coupled climate system and the local society. This study utilizes ... -
The OGS-Eclipse code for simulation of coupled multiphase flow and geomechanical processes in the subsurface
(Computational Geosciences, 2020-05-12)This paper presents a numerical simulation tool for the analysis of coupled processes related to subsurface operations. The tool combines the open-source scientific code OpenGeoSys with the reservoir simulator Eclipse ... -
The Onset of a Substorm and the Mating Instability
; (Journal of Geophysical Research: Space Physics, 2021-10-19)
The paper underlines the view that the appearance of beading and its nonlinear growth in the onset arc occurs independently from the onset of reconnection in the tail at about 20 RE. Both events follow from an extreme ... -
The Paleoseismic Database of Germany and Adjacent Regions PalSeisDB v1.0
(Historical Earthquakes, Paleoseismology, Neotectonics and Seismic Hazard: New Insights and Suggested Procedures, 2020)Central Europe is an intraplate domain which is characterized by low to moderate seismicity with records of larger seismic events occurring in historical and recent times. These records of seismicity are restricted to just ... -
The Phanerozoic thermo-tectonic evolution of northern Mozambique constrained by 40Ar/39Ar, fission track and (U-Th)/He analyses

The practice of responsible research and innovation in “climate engineering”
; (Wiley Interdisciplinary Reviews: Climate Change, 2020)
Sunlight reflection and carbon removal proposals for “climate engineering” (CE) confront governance challenges that many emerging technologies face: their futures are uncertain, and by the time one can discern their shape ... -
The regional MiKlip decadal prediction system for Europe: Hindcast skill for extremes and user‐oriented variables
; ; ; Buldmann, Benjamin; Laube, Natalie; Kadow, Christopher; Paxian, Andreas; Tiedje, Bente; ; (International Journal of Climatology, 2020-10-02)
Regional climate predictions for the next decade are gaining importance, as this period falls within the planning horizon of politics, economy, and society. The potential predictability of climate indices or extremes at ... -
The relationship between precipitation and its spatial pattern in the trades observed during EUREC4A
; ; ; (Quarterly Journal of the Royal Meteorological Society, 2022-05-16)
Trade wind convection organises into a rich spectrum of spatial patterns, often in conjunction with precipitation development. Which role spatial organisation plays for precipitation and vice versa is not well understood. ... -
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 ... -
The Role of Mineral Dust Aerosol Particles in Aviation Soot‐Cirrus Interactions
; ; (Journal of Geophysical Research: Atmospheres, 2023-01-30)
Predicting cirrus cloud properties with confidence requires a sound understanding of the relative roles of homogeneous and heterogeneous ice formation. This study explores the effect of mineral dust and contrail‐processed ... -
The Role of Moisture Conveyor Belts for Precipitation in the Atacama Desert
; ; ; (Geophysical Research Letters, 2021-12-22)
In the hyperarid Atacama Desert in northern Chile, rare precipitation events can leave long‐lasting geomorphological traces and have strong impacts on biota. While moisture conveyor belts (MCBs) and atmospheric rivers (ARs) ... -
