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.

Plasma Suppression of Large Scale Structure Formation in the Universe [PDF]
, 2007 We point out that during the reionization epoch of the cosmic history, the plasma collective effect among the ordinary matter would suppress the large scale structure formation.

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.

First test of the consistency relation for the large-scale structure using the anisotropic three-point correlation function of BOSS DR12 galaxies [PDF]
Monthly notices of the Royal Astronomical Society, 2023 We present, for the first time, an observational test of the consistency relation for the large-scale structure (LSS) of the Universe through a joint analysis of the anisotropic two- and three-point correlation functions (2PCF and 3PCF) of galaxies. We

Effects of Massive Neutrinos on the Large-Scale Structure of the Universe [PDF]
, 2011 Cosmological neutrinos strongly affect the evolution of the largest structures in the Universe, i.e. galaxies and galaxy clusters. We use large box-size full hydrodynamic simulations to investigate the non-linear effects that massive neutrinos have on ...

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-

Impact of ultralight axion self-interactions on the large scale structure of the Universe [PDF]
, 2017 Ultralight axions have sparked attention because their tiny mass m∼10-22 eV, which leads to a kiloparsec-scale de Broglie wavelength comparable to the size of a dwarf galaxy, could alleviate the so-called small-scale crisis of massive cold dark matter ...

Consistency test of general relativity from large scale structure of the Universe [PDF]
, 2009 We construct a consistency test of General Relativity (GR) on cosmological scales. This test enables us to distinguish between the two alternatives to explain the late-time accelerated expansion of the universe, that is, dark energy models based on GR ...

The Galaxy–Halo Connection of DESI Luminous Red Galaxies with Subhalo Abundance Matching
The Astrophysical Journal, 2023 We use subhalo abundance and age distribution matching to create magnitude-limited mock galaxy catalogs at z ∼ 0.43, 0.52, and 0.63 with z -band and 3.4 μ m W 1-band absolute magnitudes and r − z and r − W 1 colors. From these magnitude-limited mocks, we
