Massive Neutrinos, Galaxy Clusters and the Lyman-alpha Forest

PAB305

Simeon Bird (UC Riverside)

April 2 @ 12:00 PM - 1:00 PM

I’ll present new efficient and accurate techniques for including massive neutrinos in N-body simulations, using a linear response (to the cold dark matter) approximation for the neutrinos. Then I’ll talk about the potential for massive neutrinos to resolve some cosmological tensions within CMB observations galaxy clusters. Finally, I’ll discuss how to detect features in quasar spectra using a Gaussian Process based machine learning technique.
