Speaker
Description
Precision measurements of the cosmic microwave background’s gravitational lensing provide a uniquely powerful window into the distribution of dark matter, offering insights into neutrinos, dark energy, and enabling powerful consistency tests of the standard cosmological model.
In this talk, I will describe ongoing efforts in producing state-of-the-art CMB lensing maps from the final release of the Atacama Cosmology Telescope. By combining improved nighttime data, daytime observations, and large-scale CMB observations from Planck, these maps will deliver state-of-the-art high-fidelity lensing reconstructions over 30% of the sky. I will highlight the preliminary constraints on cosmic structure growth, neutrino mass limits and other key cosmological parameters that these maps will enable. I will also explore the transformative potential of the Simons Observatory in propelling CMB lensing science to the sub-percent precision regime, discussing the ongoing transition to SO and the potential and the technical challenges that lie ahead in next-generation mass mapping.
