An Analysis of the Large Scale N-body Simulation using the Minkowski Functionals
Takamichi Nakagami, Takahiko Matsubara, Jens Schmalzing +1
We analyze the Minkowski functionals with a large -body simulation of a standard CDM model, focusing on transition scales between linear and non-linear gravitational evolutio…
Minkowski Functionals of SDSS galaxies I : Analysis of Excursion Sets
Chiaki Hikage, Jens Schmalzing, Thomas Buchert +7
We present a first morphometric investigation of a preliminary sample from the SDSS of 154287 galaxies with apparent magnitude 14.5<m_r<17.5 and redshift 0.001<z<0.4. We measure th…
Cosmic Microwave Background polarization and the ionization history of the Universe
Pavel Naselsky, Jens Schmalzing, Jesper Sommer-Larsen +1
We point out that polarization measurements as planned for the upcoming PLANCK mission can significantly enhance the accuracy of cosmic parameter estimation compared to the tempera…
Constraints on the redshift of reionization from CMB data
Jens Schmalzing, Jesper Sommer-Larsen, Martin Goetz
We use the recent CMB power spectrum measurement by the Maxima experiment (Hanany et al. 2000) to constrain the redshift of reionization z_re. This becomes possible by combining th…
Effects of weak lensing on the topology of CMB maps
Jens Schmalzing, Masahiro Takada, Toshifumi Futamase
We investigate the non-Gaussian signatures in Cosmic Microwave Background (CMB) maps induced by the intervening large-scale structure through weak lensing. In order to measure the…
On non-Gaussianity in the Cosmic Microwave Background
Dmitri Novikov, Jens Schmalzing, Viatcheslav F. Mukhanov
We consider a cosmological model with non-Gaussian initial perturbations, which in principle could be generated in non-standard inflationary scenarios with two or more scalar field…
