Caros,
o Tiago Castro (INAF Trieste) ministrará o seguinte seminário (somente presencial) no dia 28 de abril às 14:00, sala 1 do PPGFis.
Bit by Bit: Building Galaxy Cluster Simulations for Euclid
Galaxy clusters are the most massive gravitationally bound objects in the Universe, and their abundance and spatial distribution make them powerful probes of cosmology. Extracting this information from upcoming surveys such as Euclid, however, requires theoretical predictions that are accurate enough to match the quality of the data. In this seminar, I will present recent work within the Euclid Collaboration aimed at improving three key ingredients of cluster cosmology: the halo mass function, which predicts the abundance of clusters as a function of mass; the halo bias, which describes how clusters trace the underlying matter distribution; and the impact of baryonic feedback, which can shift cluster masses away from the dark-matter-only expectation.
