Topological Defects and the Formation of Structure in the Universe [PDF]
, 1996 Topological defects, in particular cosmic strings, give rise to an interesting mechanism for generating the primordial perturbations in the early Universe which are required to explain the present structure. An overview of the cosmic string model will be

Swarm Intelligence-based Extraction and Manifold Crawling Along the Large-Scale Structure [PDF]
Monthly notices of the Royal Astronomical Society, 2023 The distribution of galaxies and clusters of galaxies on the mega-parsec scale of the Universe follows an intricate pattern now famously known as the Large-Scale Structure or the Cosmic Web. To study the environments of this network, several techniques

CMBPol Mission Concept Study: Gravitational Lensing [PDF]
, 2008 Gravitational lensing of the cosmic microwave background by large-scale structure in the late universe is both a source of cosmological information and a potential contaminant of primordial gravity waves.

Scalar–Tensor–Vector Modified Gravity in Light of the Planck 2018 Data
Universe, 2021 The recent data release by the Planck satellite collaboration presents a renewed challenge for modified theories of gravitation. Such theories must be capable of reproducing the observed angular power spectrum of the cosmic microwave background radiation.

Magnetic Fields in Galaxy Clusters and in the Large-Scale Structure of the Universe
Galaxies, 2018 The formation and history of cosmic magnetism is still widely unknown. Significant progress can be made through the study of magnetic fields properties in the large-scale structure of the Universe: galaxy clusters, filaments, and voids of the cosmic web.

Cosmological Shock Waves and Their Role in the Large-Scale Structure of the Universe [PDF]
, 2003 We study the properties of cosmological shock waves identified in high-resolution, N-body/hydrodynamic simulations of a ΛCDM universe and their role on thermalization of gas and acceleration of nonthermal, cosmic-ray (CR) particles.

Large-scale Filamentary Structure around the Protocluster at Redshift z=3.1 [PDF]
, 2005 We report the discovery of a large-scale coherent filamentary structure of Lyman alpha emitters in a redshift space at z=3.1. We carried out spectroscopic observations to map the three dimensional structure of the belt-like feature of the Lyman alpha ...

Response function of the large-scale structure of the universe to the small scale inhomogeneities [PDF]
, 2014 In order to infer the impact of the small-scale physics to the large-scale properties of the universe, we use a series of cosmological N -body simulations of self-gravitating matter inhomogeneities to measure, for the first time, the response function of

The role of energy shear in the collapse of protohaloes
Astronomy & AstrophysicsDark matter haloes form from the collapse of matter around special positions in the initial field, those where the local matter flows converge to a point. For such a triaxial collapse to take place, the energy shear tensor (the source of the evolution of
