[OKC-CosmologyGravity] C&G meeting - Oct 24 @ 13:15 in A5:1041 - talk by Steffen Hagstotz

[Raghunath Ghara]

Dear All,


We will meet again for our next C&G seminar on 24th October, tomorrow at 13:15 in room number A5:1041.

Steffen Hagstotz from the Department of Physics, SU will give a seminar on the following topic:


Title: Hunting Modified Gravity and Neutrinos with Clusters of Galaxies


Abstract:

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.



Date:        October 24, Wednesday

Time:        13:15

Place:       A5:1041


Cheers,

Jens & Raghu
