سخنران: شانت باغرام (دانشگاه صنعتی شریف، تهران) تاریخ برگزاری رویداد: دوشنبه ۲۷ بهمن ماه ۱۳۹۹

Nowadays, precision cosmology is based on the standard model of LCDM. One of the main predictions of this model is the clustered web-like distribution of matter. This distribution is the result of the hierarchical structure formation based on dark matter halo mergers and accretions. In this talk, first I will discuss how the characteristics of the cosmic web, such as the distribution of the filaments and statistics of nearest neighbor can be used as cosmological probes. Then I will show how CMB lensing and the merger history of dark matter halo can be used as observational probes to distinguish cosmological models, specifically those who address the LCDM challenges.
