Deep learning based photometric redshifts for the Kilo-Degree Survey Bright Galaxy Sample
Anjitha John William, Priyanka Jalan, Maciej Bilicki +1
In cosmological analyses, precise redshift determination remains pivotal for understanding cosmic evolution. However, with only a fraction of galaxies having spectroscopic redshift…
Dynamics of pairwise motions in the fully non-linear regime in LCDM and Modified Gravity cosmologies
Mariana Jaber, Wojciech A. Hellwing, Jorge E. García-Farieta +2
In contrast to our understanding of density field tracers, the modelling of direct statistics pertaining to the cosmic velocity field remains open to significant opportunities for…
Ghostly galaxies: accretion-dominated stellar systems in low-mass dark matter halos
Chung-Wen Wang, Andrew P. Cooper, Sownak Bose +2
Wide-area deep imaging surveys have discovered large numbers of extremely low surface brightness dwarf galaxies, which challenge galaxy formation theory and, potentially, offer new…
A Local Universe model for constrained simulations
Simon Pfeifer, Aurélien Valade, Stefan Gottlöber +3
The aim of cosmological simulations is to reproduce the properties of the observed Universe, serving as tools to test structure and galaxy formation models. Constrained simulations…
Hierarchical structure of the cosmic web and galaxy properties
Mariana Jaber, Marius Peper, Wojciech A. Hellwing +2
Voids possess a very complex internal structure and dynamics. Using -body simulations we study the hierarchical nature of sub-structures present in the cosmic web (CW). We use t…
Improved analytical modeling of the non-linear power spectrum in modified gravity cosmologies
Suhani Gupta, Wojciech A. Hellwing, Maciej Bilicki
Reliable analytical modeling of the non-linear power spectrum (PS) of matter perturbations is among the chief pre-requisites for cosmological analyses from the largest sky surveys.…
