Unbiased contaminant removal for 3D galaxy power spectrum measurements
Benedict Bahr-Kalus, Will J Percival, David Bacon +1
We assess and develop techniques to remove contaminants when calculating the 3D galaxy power spectrum. We separate the process into three separate stages: (i) removing the contamin…
Cosmological parameter inference from galaxy clustering: The effect of the posterior distribution of the power spectrum
Benedict Bahr-Kalus, Will J. Percival, Lado Samushia
We consider the shape of the posterior distribution to be used when fitting cosmological models to power spectra measured from galaxy surveys. At very large scales, Gaussian poster…
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…
On the accelerated expansion of the cosmos
Dominik J. Schwarz, Benedict Bahr-Kalus, Marina Seikel
We present a short (and necessarily incomplete) review of the evidence for the accelerated expansion of the Universe. The most direct probe of acceleration relies on the detailed s…
