Is the Observable Universe Consistent with the Cosmological Principle?
Pavan Kumar Aluri, Paolo Cea, Pravabati Chingangbam +20
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 conven…
Directional Variations of Cosmological Parameters from the Planck CMB Data
Shek Yeung, Ming-Chung Chu
Recent observations suggest that there are violations of the isotropy of the universe at large scales, an important part of the cosmological principle. In this paper, we use the Co…
Effects of Neutrino Masses and Asymmetries on Dark Matter Halo Assembly
Hiu Wing Wong, Ming-chung Chu
Massive cosmological neutrinos suppress the Large-Scale Structure (LSS) in the Universe by smoothing the cosmic over-densities, and hence structure formation is delayed relative to…
Metamorphosis of dwarf halo density profile under dark matter decays
Jianxiong Chen, M. -C. Chu
We study the density profile of a dwarf halo in the decaying dark matter (DDM) cosmology, using a new algorithm that resolves halo density profiles down to the innermost pc r…
Relic Neutrino Degeneracies and Their Impact on Cosmological Parameters
Shek Yeung, King Lau, M. -C. Chu
In the standard CDM model, neutrinos are treated as radiation, with their masses and possible degeneracy ignored. In this paper, we compute the impact of a finite relic neutrino…
Cosmological Simulation for Fuzzy Dark Matter Model
Jiajun Zhang, Hantao Liu, Ming-Chung Chu
Fuzzy Dark Matter (FDM), motivated by string theory, has recently become a hot candidate for dark matter. The rest mass of FDM is believed to be eV and the correspon…
