    • Cosmological solutions of the Einstein-Vlasov-scalar field system 

      Tegankong, David (Univ. Berlin, 2005)
      The aim of this thesis is to obtain as much information as possible, about global solutions of the Cauchy problem for the Einstein-Vlasov-scalar field system with spherical, plane and hyberbolic symmetries written in areal ...
    • Cosmology through gravitational lenses 

      Rubio, Rodrigo Gil-Merino (Univ. Potsdam, 2004)
      In dieser Dissertation nutze ich den Gravitationslinseneffekt, um eine Reihe von kosmologischen Fragen zu untersuchen. Der Laufzeitunterschied des Gravitationslinsensystems HE1104-1805 wurde mit unterschiedlichen Methoden ...
    • Data analysis of continuous gravitational waves 

      Ghadikolaei, Iraj Gholami (Univ. Potsdam, 2008)
      This thesis describes two main projects; the first one is the optimization of a hierarchical search strategy to search for unknown pulsars. This project is divided into two parts; the first part (and the main part) is the ...
    • Eigenschaften von kompakten Sternen in QCD-motivierten Modellen 

      Hanauske, Matthias (Univ. Frankfurt (Main), 2005)
      Kompakte Sterne stellen neben weissen Zwergen und schwarzen Löchern eine der möglichen Endzustände der Evolution von Sonnen dar. Diese extrem dichten astrophysikalischen Objekte können als Restobjekte von massiven Sternen ...
    • Stellar iron core collapse in {3+1} general relativity and the gravitational wave signature of core-collapse supernovae 

      Ott, Christian David (Univ. Potsdam, 2007)
      I perform and analyse the first ever calculations of rotating stellar iron core collapse in {3+1} general relativity that start out with presupernova models from stellar evolutionary calculations and include a microphysical ...
