RascalC: A Jackknife Approach to Estimating Single and Multi-Tracer Galaxy Covariance Matrices

Oliver H. E. Philcox, Daniel J. Eisenstein, Ross O'Connell +1

To make use of clustering statistics from large cosmological surveys, accurate and precise covariance matrices are needed. We present a new code to estimate large scale galaxy two-…

The clustering of galaxies in the SDSS-III Baryon Oscillation Spectroscopic Survey: Evolution of higher-order correlations demonstrated with Minkowski Functionals

James M. Sullivan, Alexander Wiegand, Daniel J. Eisenstein

We probe the higher-order galaxy clustering in the final data release (DR12) of the Sloan Digital Sky Survey Baryon Oscillation Spectroscopic Survey (BOSS) using germ-grain Minkows…

The clustering of galaxies in the SDSS-III Baryon Oscillation Spectroscopic Survey: higher-order correlations revealed by germ-grain Minkowski Functionals

Alexander Wiegand, Daniel J. Eisenstein

We probe the higher-order clustering of the galaxies in the final data release (DR12) of the Sloan Digital Sky Survey Baryon Oscillation Spectroscopic Survey (BOSS) using the metho…

Direct Minkowski Functional analysis of large redshift surveys: a new high--speed code tested on the luminous red galaxy Sloan Digital Sky Survey-DR7 catalogue

Alexander Wiegand, Thomas Buchert, Matthias Ostermann

As deeper galaxy catalogues are soon to come, it becomes even more importantto measure large-scale fluctuations in the catalogues with robust statistics that cover all moments of t…

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…

Inhomogeneity-induced variance of cosmological parameters

Alexander Wiegand, Dominik J. Schwarz

Modern cosmology relies on the assumption of large-scale isotropy and homogeneity of the Universe. However, locally the Universe is inhomogeneous and anisotropic. So, how can local…
