Contributions to the nonlinear integrated Sachs-Wolfe effect: Birkinshaw-Gull effect and gravitational self-energy density
Philipp Merkel, Bjoern Malte Schaefer
In this paper, we recompute contributions to the spectrum of the nonlinear integrated Sachs-Wolfe (iSW)/Rees-Sciama effect in a dark energy cosmology. Focusing on the moderate nonl…
Cross bispectra and trispectra of the non-linear integrated Sachs-Wolfe effect and the tracer galaxy density field
Gero Jürgens, Björn Malte Schäfer
In order to investigate possibilities to measure non-Gaussian signatures of the non-linear iSW effect, we study in this work the family of mixed bispectra <tau^q gamma^(3-q)> and t…
The interplay of CMB temperature lensing power reconstruction with primordial non-Gaussianity of local type
Philipp M. Merkel, Bjoern Malte Schaefer
In the current era of high-precision CMB experiments, the imprint of gravitational lensing on the CMB temperature is exploited as a source of valuable information. Especially the r…
Evolution of intrinsic ellipticity correlations due to peculiar motion
Aram Giahi-Saravani, Bjoern Malte Schaefer
Topic of this paper is the time-evolution of intrinsic correlations of galaxy ellipticities due to peculiar motion. In our model, the galaxy ellipticities are determined from the a…
Integrated Sachs-Wolfe tomography with orthogonal polynomials
Gero Jürgens, Bjoern Malte Schäfer
Topic of this article are tomographic measurements of the integrated Sachs-Wolfe effect with specifically designed, orthogonal polynomials which project out statistically independe…
