<p dir="ltr" style="line-height:1.38;margin-top:0pt;margin-bottom:0pt;"><span style="font-size: 11.5pt; font-family: Arial; color: rgb(33, 33, 33); font-variant-numeric: normal; font-variant-east-asian: normal; vertical-align: baseline; white-space: pre-wrap;">Considerable
effort in cosmology is focused on understanding the statistical nature of the cosmological density field that underlies the observable large-scale structure. Clusters of galaxies trace the highest, non-Gaussian peaks of the matter density, and their abundance
is a sensitive probe of both underlying cosmological parameters as well as of the physics governing structure formation. In my talk I will explain how cluster abundance can be used to search for modifications of gravity via the impact on spherical collapse
and why neutrinos are a crucial component in these searches. In addition, astrophysical signatures within the cluster can be a key signal themselves and I will demonstrate how to incorporate them consistently in searches to constrain deviations from general
relativity.</span></p>
