Description
The cosmic web is a complex network of thin walls, elongated filaments, and dense clusters that map the overall distribution of dark matter density in the universe. Dark matter haloes, which are collapsed structures, form and expand due to gravitational instability caused by slight initial density variations in the cosmic field. Understanding the properties of subhaloes within these haloes is crucial for studying the impact of their location within the cosmic web on the parent haloes and the galaxies they host. While there is evidence that the characteristics of dark matter haloes and the galaxies they contain vary across different cosmic web environments, the dependence of dark matter subhalo properties on their cosmic web environment requires further investigation. In this study, using a high-resolution N-body simulation we investigate how the mass function, concentration, velocity function, and radial distribution of dark matter subhaloes depend on the cosmic web environment. We also investigated the redshift evolution of these properties and their alignment with the large-scale structure of haloes in filaments, sheets, and voids. In this presentation, I will discuss our comprehensive results on the relationship between dark matter subhalo properties and the cosmic web environment.
