Inflationary study of non-Gaussianity using two-dimensional geometrical measures of CMB temperature maps
M. Junaid, D. Pogosyan
In this work we effectively calculated the two-dimensional Minkowski functionals for cosmic microwave background (CMB) temperature maps generated by single field models of inflatio…
Geometrical measures of non-Gaussianity generated from single field Inflationary models
M. Junaid, D. Pogosyan
We have calculated the third order moments of scalar curvature perturbations in configuration space for different inflationary models. We developed a robust numerical technique to…
Spin alignments within the cosmic web: a theory of constrained tidal torques near filaments
Sandrine Codis, Christophe Pichon, Dmitry Pogosyan
The geometry of the cosmic web drives in part the spin acquisition of galaxies. This can be explained in a Lagrangian framework, by identifying the specific long-wavelength correla…
Planck 2015 results. XVIII. Background geometry & topology
Planck Collaboration, P. A. R. Ade, N. Aghanim +223
Full-sky CMB maps from the 2015 Planck release allow us to detect departures from global isotropy on the largest scales. We present the first searches using CMB polarization for co…
Why do galactic spins flip in the cosmic web? A Theory of Tidal Torques near saddles
Christophe Pichon, Sandrine Codis, Dmitry Pogosyan +3
Filaments of the cosmic web drive spin acquisition of disc galaxies. The point process of filament-type saddle represent best this environment and can be used to revisit the Tidal…
Dancing in the dark: galactic properties trace spin swings along the cosmic web
Yohan Dubois, Christophe Pichon, Charlotte Welker +30
A large-scale hydrodynamical cosmological simulation, Horizon-AGN, is used to investigate the alignment between the spin of galaxies and the cosmic filaments above redshift 1.2. Th…
