Adventures in the non-linear regime of CMB lensing and large-scale structure

01.12.2017 12:00 – 13:00

If the next generation of cosmological surveys are to realise their potential of discovering new physics, more effort must be directed towards understanding non-linear contributions to probes of cosmic density fluctuations. My talk will cover two examples of recent progress in this endeavour. In the first half I will discuss a new method aimed at enhancing the information content of clustering statistics with non-linear Gaussianizing transforms. In the second half I will present recent calculations of several new contributions to the lensed CMB and discuss their implications for measuring primordial gravitational waves.
