Title: Cosmological constraints from tSZ power spectrum and cluster counts
Abstract: In this talk we will review the formalism for the modelling of the Sunyaev Zeldovich (SZ) power spectrum and cluster counts and how to compare them with observations. We will outline their dependencies on cosmological parameters, as well as the mass bias associated with the X-ray calibration of the cluster masses. Then, we will discuss the consistency between Planck SZ data, Planck Primary CMB, and other LSS probes. Finally, we will study constraints on extensions of the LCDM cosmology by including massive neutrinos and the equation of state of dark energy in the SZ analyses.

Abstract: We discuss the evolution of pure states through two quences in the SYK Model. The first quench pumps energy out of the system. In the bulk dual this corresponds to starting with a black hole spacetime and beyond a critical perturbation the geometry horizon disappears. The second quench pumps energy into the system and one observes the formation of a horizon asymptotically in time. This black hole temperature has a Choptuik like scaling form with exponent 1/2.
