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 ... -
X-ray studies of ultraluminous infrared galaxies observed with XMM-Newton

Year‐round sub‐seasonal forecast skill for Atlantic–European weather regimes
(Quarterly Journal of the Royal Meteorological Society, 2021-10-25)Weather regime forecasts are a prominent use case of sub‐seasonal prediction in the midlatitudes. A systematic evaluation and understanding of year‐round sub‐seasonal regime forecast performance is still missing, however. ... -
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, ... -
Zeeman-Doppler Imaging of active late-type stars
(Univ. Potsdam, 2009)Stellar magnetic fields, as a crucial component of star formation and evolution, evade direct observation at least with current and near future instruments. However investigating whether magnetic fields are generated by a ... -
Zonal Wave Number Diagnosis of Rossby Wave-Like Oscillations Using Paired Ground-Based Radars
(Journal of Geophysical Research: Atmospheres, 2020)Free traveling Rossby wave normal modes (RNMs) are often investigated through large-scale space-time spectral analyses, which therefore is subject to observational availability, especially in the mesosphere. Ground-based ... -
Zur Entstehung kleinräumiger, kohärenter Bodendrucksignaturen über der Norddeutschen Tiefebene
(Univ. Hannover, 2006)Meßkampagnen mit Mikrobarometermeßnetzen haben in der Vergangenheit gezeigt, daß sich in den Drucksignaturen nahezu permanent räumlich kohärente Strukturen (KST) abbilden. Ein Teil dieser KST wird durch Schwerewellen ... -
Zur Ermittlung geophysikalischer Massensignale mit Schwerefeldmissionen - eine Analyse des gegenwärtigen Standes am Beispiel der Antarktis
(Univ. Dresden, 2007)Die neuen Schwerefeld-Satellitenmissionen CHAMP (Challenging Minisatellite Payload), GRACE (Gravity Recovery and Climate Experiment) und GOCE (Gravity Field and Steady-State Ocean Circulation Explorer) können wesentlich ... -
Zur Geschichte der Geophysik in Deutschland - Jubiläumsschrift zur 75jährigen Wiederkehr der Gründung der Deutschen Geophysikalischen Gesellschaft
(Deutsche Geophysikalische Gesellschaft, Hamburg, 1997)Die Jubiläumsschrift zum 75jährigen Bestehen der Deutschen Geophysikalischen Gesellschaft (DGG) enthält zahlreiche Beiträge von Mitgliedern zu vier Schwerpunkten: 1) Eine Aktualisierung der Geschichte der DGG vor allem ... -
Zur Lösung nichtlinearer Ausgleichungsprobleme bei der Bestimmung von Frequenzen in Zeitreihen
(Univ. Berlin, 2000)With regard to geodesy optimizing procedures for nonlinear adjustment problems are presented. The procedures can be divided into local and global optimization techniques according to the type of the problem. If good initial ...
