Malaco temperature reconstructions and numerical simulation of environmental conditions in the southeastern Carpathian Basin during the Last Glacial Maximum
(Journal of Quaternary Science, 2021-05-05)We investigate the glacial climate conditions in the southeastern Carpathian Basin (Vojvodina, Serbia) based on the reconstruction of malacological palaeotemperatures and results from a high‐resolution regional climate ... -
Mantle and Crustal Sources of Magmatic Activity of Klyuchevskoy and Surrounding Volcanoes in Kamchatka Inferred From Earthquake Tomography
(Journal of Geophysical Research: Solid Earth, 2020-09-28)Klyuchevskoy and surrounding volcanoes in central Kamchatka form the Northern Group of Volcanoes (NGV), which is an area of particularly diverse and intensive Pleistocene‐Holocene volcanism. In this study, we present a new ... -
Mantle Anisotropy in NW Namibia From XKS Splitting: Effects of Asthenospheric Flow, Lithospheric Structures, and Magmatic Underplating
(Geophysical Research Letters, 2023-01-27)The presence of the Etendeka flood basalts in northwestern Namibia is taken as evidence for the activity of the Tristan da Cunha mantle plume during the continental breakup between Africa and South America. We investigate ... -
Mapping and assessment of land use, land cover using remote sensing and GIS in North Kordofan State, Sudan
(Univ. Dresden, 2006)Sudan as a Sahelian country faced numerous drought periods resulting in famine and mass immigration. Spatial data on dynamics of land use and land cover is scarce and/or almost nonexistent. The study area in the North ... -
Mapping and Understanding Patterns of Air Quality Using Satellite Data and Machine Learning
(Journal of Geophysical Research: Atmospheres, 2020)The quantification of factors leading to harmfully high levels of particulate matter (PM) remains challenging. This study presents a novel approach using a statistical model that is trained to predict hourly concentrations ... -
Mapping the Brightness of Ganymede's Ultraviolet Aurora Using Hubble Space Telescope Observations
(Journal of Geophysical Research: Planets, 2022-06-15)We analyze Hubble Space Telescope observations of Ganymede made with the Space Telescope Imaging Spectrograph between 1998 and 2017 to generate a brightness map of Ganymede's oxygen emission at 1,356 Å. Our Mercator projected ... -
Mapping the Thermal Structure of Southern Africa From Curie Depth Estimates Based on Wavelet Analysis of Magnetic Data With Uncertainties
(Geochemistry, Geophysics, Geosystems, 2021-11-16)Surface heat flow provides essential information on the thermal state and thickness of the lithosphere. Southern Africa is a mosaic of the best‐preserved and exposed crustal blocks, assembled in the early late Archean and ... -
Marine gravimetric and magnetic investigations within the area of the southeastern Mediterranean Sea and the northern section of Egypt
(Univ. Hamburg, 2004)The southeastern Mediterranean Sea and the northern section of Egypt constitutes one of the most complex tectonic areas in the Mediterranean. This study is an attempt to achieve a better understanding of tectonics, and ... -
Martian Atmospheric Spectral End‐Members Retrieval From ExoMars Thermal Infrared (TIRVIM) Data
(Journal of Geophysical Research: Planets, 2022-09-09)Key knowledge about planetary composition can be recovered from the study of thermal infrared spectral range datasets. This range has a huge diagnostic potential because it contains diagnostic absorptions from a planetary ... -
Mass distribution at the galactic centre
(Univ. Köln, 2005)In the framework of this PhD thesis, the study of the distribution of an extended mass close to the super-massive black hole (SMBH) at the centre of our Galaxy is addressed using observational data and theoretical modelling. ... -
Masses of small bodies - mass estimation of small solar system bodies using radio science data from close flybys
(Univ. Köln, 2010)The Radio Science technique enables to estimate the mass and other gravitational parameters of a solar system body from spacecraft observations very precisely. It uses the radio link between ground station and spacecraft. ... -
Massive stars in the Galactic Center Quintuplet cluster
(Univ. Potsdam, 2009)The presented thesis describes the observations of the Galactic center Quintuplet cluster, the spectral analysis of the cluster Wolf-Rayet stars of the nitrogen sequence to determine their fundamental stellar parameters, ... -
Mean‐State Dependence of CO2‐Forced Tropical Atlantic Sector Climate Change
(Geophysical Research Letters, 2021-10-03)Twenty‐first‐century climate change projections are uncertain, especially on regional scales. An important source of uncertainty is that climate models exhibit biases, which limits their ability to predict climate. One of ... -
Measurement of the energy spectrum of the BL Lac object PG1553+113 with the MAGIC telescope in 2005 and 2006
(Univ. Berlin, 2007)In dieser Doktorarbeit wurden im Rahmen des MAGIC Experimentes neue Datenanalysemethoden implementiert, die sich insbesondere fuer die Analyse von Ereignissen niedriger Gammastrahlungsenergie eignen. Die Methoden konnten ... -
