Abstract The standard Λ Cold Dark Matter (ΛCDM) cosmological model provides a good
description of a wide range of astrophysical and cosmological data. However, there are a …

The cosmological principle (CP)—the notion that the Universe is spatially isotropic and
homogeneous on large scales—underlies a century of progress in cosmology. It is …

The cosmic web is the largest scale manifestation of the anisotropic gravitational collapse of
matter. It represents the transitional stage between linear and non-linear structures and …

Galaxy counts and recent measurements of the luminosity density in the near-infrared have
indicated the possibility that the local universe may be under-dense on scales of several …

A large quasar group (LQG) of particularly large size and high membership has been
identified in the DR7QSO catalogue of the Sloan Digital Sky Survey. It has characteristic size …

Abstract Horizon Run 5 (HR5) is a cosmological hydrodynamical simulation that captures
the properties of the universe on a Gpc scale while achieving a resolution of 1 kpc. Inside …

Using the redshift space distortions of void–galaxy cross-correlation function we analyse the
dynamics of voids embedded in different environments. We compute the void–galaxy cross …

We investigate the impact of the number of filaments connected to the nodes of the cosmic
web on the physical properties of their galaxies using the Sloan Digital Sky Survey. We …

We perform a statistical study focused on void environments. We examine galaxy density
profiles around voids in the Sloan Digital Sky Survey (SDSS), finding a correlation between …

Based on data from the Galaxy and Mass Assembly (GAMA) survey, we report on the
discovery of structures that we refer to as 'tendrils' of galaxies: coherent, thin chains of …
