Regularity of the Large-Scale Structure of the Universe [PDF]
Symposium - International Astronomical Union, 1999 The observed structure of the Universe is hierarchical. Galaxies and clusters of galaxies are concentrated within elongated filamentary chains of various richness. High-density regions of the Universe form superclusters consisting of one or several clusters of galaxies and chains of galaxies surrounding and joining clusters. The space between filaments

The Theory of the Large Scale Structure of the Universe [PDF]
Symposium - International Astronomical Union, 1978 The God-father of psychoanalysis Professor Sigmund Freud taught us that the behaviour of adults depends on their early childhood experiences. in the same spirit, the problem of cosmological analysis is to derive the observed present day situation and structure of the Universe from certain plausible assumptions about its early behaviour.

Systematic Effects on the Genus Topology of Large Scale Structure of the Universe [PDF]
, 2014 Large-scale structure of the universe is a useful cosmological probe of the primordial non-Gaussianity and the expansion history of the universe because its topology does not change with time in the linear regime in the standard paradigm of structure ...

Statistical Analysis of Large-Scale Structure in the Universe [PDF]
, 2007 Methods for the statistical characterization of the large-scale structure in the Universe will be the main topic of the present text. The focus is on geometrical methods, mainly Minkowski functionals and the J-function. Their relations to standard methods used in cosmology and spatial statistics and their application to cosmological datasets will be ...

Field-level Neural Network Emulator for Cosmological N-body Simulations
The Astrophysical Journal, 2023 We build a field-level emulator for cosmic structure formation that is accurate in the nonlinear regime. Our emulator consists of two convolutional neural networks trained to output the nonlinear displacements and velocities of N -body simulation ...

Ho’oleilana: An Individual Baryon Acoustic Oscillation?
The Astrophysical Journal, 2023 Theory of the physics of the early hot universe leads to a prediction of baryon acoustic oscillations (BAOs) that has received confirmation from the pairwise separations of galaxies in samples of hundreds of thousands of objects.

On the ε cosmological parameter [PDF]
Serbian Astronomical Journal, 2015 In the paper On asymptotic solutions of Friedmann equations (Mijajlović et al. 2012), the theory of regularly varying functions in the sense of Karamata is applied in an asymptotic analysis of solutions of Friedmann equations.

The Astrophysical Journal, 2023 We present two new diagnostics based on the intrinsic shape alignments of group/cluster size dark matter halos to disentangle the effect of f ( R ) gravity from that of massive neutrinos.

Large-scale homogeneity in the distribution of quasars in the Hercules-Corona Borealis Great Wall region [PDF]
Serbian Astronomical Journal, 2022 In light of recent debates on the existence of a gigaparsec-scale structure traced by gamma-ray bursts, namely the Hercules-Corona Borealis Great Wall (HCBGW), we revisit large-scale homogeneity in the spatial distribution of quasars. Our volume-
