Effects of tidal gravitational fields in clustering dark energy models
Francesco Pace, Robert Reischke, Sven Meyer +1
We extend a previous work by Reischke et al., 2016 by studying the effects of tidal shear on clustering dark energy models within the framework of the extended spherical collapse m…
Shear and vorticity in the spherical collapse of dark matter haloes
Robert Reischke, Francesco Pace, Sven Meyer +1
Traditionally the spherical collapse of objects is studied with respect to a uniform background density, yielding the critical over-density as key ingredient to the…
Variations of cosmic large-scale structure covariance matrices across parameter space
Robert Reischke, Alina Kiessling, Björn Malte Schäfer
The likelihood function for cosmological parameters, given by e.g. weak lensing shear measurements, depends on contributions to the covariance induced by the nonlinear evolution of…
Spherical collapse of dark matter haloes in tidal gravitational fields
Robert Reischke, Francesco Pace, Sven Meyer +1
We study the spherical collapse model in the presence of external gravitational tidal shear fields for different dark energy scenarios and investigate the impact on the mass functi…
Describing variations of the Fisher-matrix across parameter space
Björn Malte Schäfer, Robert Reischke
Forecasts in cosmology, both with Monte-Carlo Markov-chain methods and with the Fisher matrix formalism, depend on the choice of the fiducial model because both the signal strength…
