Constraints on anisotropic cosmic expansion from supernovae
Benedict Bahr-Kalus, Dominik J. Schwarz, Marina Seikel +1
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). We compare t…
We do not live in the R_h = c t universe
Maciej Bilicki, Marina Seikel
We analyse the possibility that our Universe could be described by the model recently proposed by Melia & Shevchuk (2012), where the Hubble scale R_h=c/H is at all times equal to t…
Reconstruction of dark energy and expansion dynamics using Gaussian processes
Marina Seikel, Chris Clarkson, Mathew Smith
An important issue in cosmology is reconstructing the effective dark energy equation of state directly from observations. With few physically motivated models, future dark energy s…
Using H(z) data as a probe of the concordance model
Marina Seikel, Sahba Yahya, Roy Maartens +1
Direct observations of the Hubble rate, from cosmic chronometers and the radial baryon acoustic oscillation scale, can out-perform supernovae observations in understanding the expa…
