Title: Nevo: illuminating the dark cosmos
Speaker: Farbod Hassani (University of Oslo)
Abstract:
The Universe has entered an accelerating expansion phase in the last few billion years of its evolution, a phenomenon that is caused by the mysterious entity known as dark energy.
To understand the nature of dark energy, we must carefully investigate different candidates and observe how they affect the Universe at various stages. Then we may utilize data to select the best candidate. However, the consistent and accurate modeling of dark energy candidates has been largely neglected so far due to significant challenges, including the absence of relativistic N-body codes, the immense computational costs involved, and the limited availability of relevant data to date. To address this gap, we have proposed the development of a novel framework, called NEVO, that utilizes state-of-the-art “relativistic” N-body simulations along with the advanced Boltzmann codes, to accurately model dark energy candidates in both linear and non-linear scales. In this presentation, I will go into detail about the awarded NEVO proposal and discuss its challenges in depth.
