SUMMARY:High-precision CMB lensing measurements with the Atacama Cosmology
  Telescope: a new probe of cosmology and fundamental physics - Frank J. Qu

DESCRIPTION:Dark matter not only provides the invisible scaffolding from w
 hich the birth of galaxies takes place\, but by studying its distribution 
 in our universe we can infer a great deal of information regarding the gro
 wth of structure and cosmic expansion. Measuring the gravitational lensing
  of the CMB allows the mapping of all the matter distribution (for which t
 he majority is dark matter) to very high redshifts\, providing a clean win
 dow for constraining fundamental physics. In this talk\, I will present ne
 w CMB lensing measurements derived from data release 6 of the Atacama Cosm
 ology Telescope\, which provides a state-of-the-art lensing power spectrum
  measurement of 43 \\sigma and an associated signal-dominated lensing mass
  map that will enable a host of cosmological and astrophysical science goa
 ls. I will discuss in detail the novel methods used to tackle key systemat
 ics affecting precision CMB lensing and explore the implications of our me
 asurements in the context of structure growth and how it can weigh in on t
 he S8 tension.
