CG: NumCosmo halo tools: application to cluster cosmology and cluster mass estimation – Penna Lima V.

April 19 @ 11:15 am 12:00 pm CMT

Galaxy clusters are important cosmological probes since their abundance and spatial distribution are directly linked to structure formation on large scales. The principal uncertainty source on the cosmological parameter constraints concerns the cluster mass estimation from mass proxies. In addition, future surveys will provide a large amount of data, requiring an improvement in the accuracy of other elements used in the construction of cluster likelihoods. Therefore, accurate modeling of the mass-observable relations and reducing the effect of different systematic errors are fundamental steps for the success of cluster cosmology. In this work, we present a brief review on that topic, and also describe some tools implemented in the Numerical Cosmology Library, and the cross-check with other public libraries.
