    • Constraints on anisotropic cosmic expansion from supernovae 

      Kalus, Benedict; Schwarz, Dominik J.; Seikel, Marina; Wiegand, Alexander (Edp Sciences, 2013)
      AIMS. We test the isotropy of the expansion of the Universe by estimating the hemispherical anisotropy of supernova type Ia (SN Ia) Hubble diagrams at low redshifts (z < 0.2). METHODS. We compare the best fit Hubble ...

    • Testing foundations of modern cosmology with SKA all-sky surveys 

      Schwarz, Dominik J.; Bacon, David; Chen, Song; Clarkson, Chris; Huterer, Dragan; Kunz, Martin; Maartens, Roy; Raccanelli, Alvise; Rubart, Matthias; Starck, Jean-Luc (Proceedings of Science, 2014)
      Continuum and HI surveys with the Square Kilometre Array (SKA) will allow us to probe some of the most fundamental assumptions of modern cosmology, including the Cosmological Principle. SKA all-sky surveys will map an ...
