Characterization of anisotropic Gaussian random fields by Minkowski tensors

Michael Andreas Klatt et al.

Summary: This article investigates the expected Minkowski tensors (MTs) of level sets of Gaussian random fields and confirms the explicit expressions for interfacial MTs through detailed simulations. It demonstrates the ability of MTs to detect and characterize the anisotropy of level sets, and clarifies the shape information contained in MTs of different ranks. Furthermore, it discovers that even under the assumption of Gaussian distribution, it is possible to predict the anisotropy information in higher-rank tensors, which proves useful for detecting non-Gaussianities in anisotropic random fields.

A Challenge to the Standard Cosmological Model

Nathan J. Secrest et al.

Summary: This study presents the joint analysis of catalogs of radio galaxies and quasars to examine their distribution in the sky in relation to the standard cosmological model. The results show that both radio galaxies and quasars have dipole anisotropy in their sky distribution, consistent with the motion inferred from the cosmic microwave background (CMB), suggesting an intrinsic anisotropy in cosmologically distant sources.

Prospects of constraining reionization model parameters using Minkowski tensors and Betti numbers

Akanksha Kapahtia et al.

Summary: The study explores the possibility of constraining model parameters of the Epoch of Reionization (EoR) from 21cm brightness temperature maps. The results show that the average size and isotropy of structures in the field are important factors, and that noisy Tb maps need to be smoothed to recover the input model. The systematic behavior of the statistic as ionization progresses enables stringent constraints on the mean neutral hydrogen fraction, making these descriptors promising statistics for constraining EoR model parameters and the ionization history of the universe.

The nature of non-Gaussianity and statistical isotropy of the 408 MHz Haslam synchrotron map

Fazlu Rahman et al.

Summary: Accurate component separation in full-sky maps at radio and microwave frequencies, like the CMB, requires a deep understanding of the statistical properties of Galactic foreground emissions. Analysis of the statistical properties of Galactic synchrotron using scalar Minkowski functionals and Minkowski tensors reveals high non-Gaussian deviations at the smallest angular scales. Non-Gaussian nature can be explained by perturbative expansion up to second-order terms, with kurtosis terms being dominant over skewness terms.Tests show that the Haslam map becomes increasingly more isotropic at smaller scales.

Local patch analysis for testing statistical isotropy of the Planck convergence map

Priya Goyal et al.

Summary: This study uses the measurement results of weak gravitational lensing on the cosmic microwave background radiation to test the fundamental assumption of Statistical Isotropy (SI) of the universe, finding that the observed data is consistent with SI overall, but there are local regions with deviations with statistical significance higher than 95% confidence level.

Persistent homology of the cosmic web - I. Hierarchical topology in ΛCDM cosmologies

Georg Wilding et al.

Summary: By utilizing multiscale topological data analysis tools, this study tracks the evolution of connectivity and topological structure changes in the cosmic web through Betti number curves and persistence diagrams. The persistence diagrams provide a higher level of information on the structure formation process compared to global summary statistics.

Morphology of weak lensing convergence maps

D. Munshi et al.

Summary: The study focuses on the morphology of convergence maps by perturbatively reconstructing their Minkowski functionals. A systematic investigation using a set of generalized skew spectra as leading-order corrections to Gaussian MFs in the quasi-linear regime is presented. The method allows for unbiased reconstruction of MFs in the presence of masks and noise, and comparisons with numerical simulations show excellent agreement. Additionally, the study explores the importance of post Born corrections for modelling non-Gaussianity in convergence maps at higher redshifts.

Summary: The statistical isotropy of the E-mode polarization of the cosmic microwave background radiation observed by the Planck satellite was tested using the alpha estimator and directional statistic. Results showed good agreement between the Planck data and simulations in terms of statistical properties.

A Test of the Cosmological Principle with Quasars

Nathan J. Secrest et al.

Summary: The study reveals that the direction of the dipole in the quasar sky is similar to that of the cosmic microwave background (CMB), but its amplitude is over twice as large as expected, rejecting the canonical interpretation of the CMB dipole. This conflicts with the cosmological principle, a foundational assumption of the concordance ΛCDM model.

Cosmological Parameter Estimation from the Two-dimensional Genus Topology-Measuring the Expansion History Using the Genus Amplitude as a Standard Ruler

Stephen Appleby et al.

Summary: The study uses the genus of galaxy distribution to constrain cosmological parameters, with constraints on the dark energy equation of state at w(de) = 1.05-(0.13)(0.12) and the matter density parameter at Omega(m).=.0.303.+/-.0.036. Combining high- and low-redshift data with Planck CMB data provides stronger constraints.
