DOI: 10.1080/00107514.2017.1291739
Abstract: Several of the papers concern themselves with the relationship between ‘reality’, ‘model’ and ‘knowledge’. Although a central issue is whether it is possible to gain knowledge of ‘reality’ (empiricism vs. rationalism), the primary goal of… read more here.

DOI: 10.1088/1475-7516/2018/05/027
Abstract: We present a general formalism for identifying the caustic structure of an evolving mass distribution in an arbitrary dimensional space. For the class of Hamiltonian fluids the identification corresponds to the classification of singularities in… read more here.

DOI: 10.1088/1674-4527/addf04
Abstract: In this study, we investigate the potential of mark-weighted angular correlation functions, which integrate β-cosmic-web classification with angular correlation function analysis to improve cosmological constraints. Using SDSS DR12 CMASS-NGC galaxies and mock catalogs with Ωm… read more here.

DOI: 10.1093/mnras/staa1059
Abstract: The standard cosmological model ($\Lambda$CDM) predicts the existence of the cosmic web: a distribution of matter into sheets and filaments connecting massive halos. However, observational evidence has been elusive due to the low surface brightness… read more here.

DOI: 10.1093/mnras/stw2715
Abstract: We investigate the spin evolution of dark matter haloes and their dependence on the number of connected filaments from the cosmic web at high redshift (spin-filament relation hereafter). To this purpose, we have simulated $5000$… read more here.

DOI: 10.1093/mnras/sty037
Abstract: Cosmological simulations suggest that most of the matter in the Universe is distributed along filaments connecting galaxies. Illuminated by the cosmic UV background (UVB), these structures are expected to glow in fluorescent Ly α emission with… read more here.

DOI: 10.1093/mnras/stz1243
Abstract: Gravitational collapse in cosmological context produces an intricate cosmic web of voids, walls, filaments and nodes. The anisotropic nature of collisionless collapse leads to the emergence of an anisotropic velocity dispersion, or stress, that absorbs… read more here.

DOI: 10.1093/mnras/stz1399
Abstract: Galaxy filaments are a peculiar environment, and their impact on the galaxy properties is still controversial. Exploiting the data from the GAs Stripping Phenomena in galaxies with MUSE (GASP), we provide the first characterisation of… read more here.

DOI: 10.1093/mnras/stz2344
Abstract: The internal properties of dark matter haloes correlate with the large-scale halo clustering strength at fixed halo mass – an effect known as assembly bias – and are also strongly affected by the local, non-linear… read more here.
