Description
Investigating non-Gaussianity from CMB secondary sources with the Atacama Cosmology Telescope
The bispectrum of the cosmic microwave background (CMB) is dominated at at all scales by CMB secondary sources; this makes it a powerful tool to constrain their physics. In this talk, I will discuss our work studying the contributions of radio galaxies, thermal Sunyaev Zeldovich clusters and dusty star forming galaxies to the cosmic microwave background's bispectrum. We demonstrate the ability to simultaneously measure the one halo contributions with the Atacama Cosmology Telescope. Finally we discuss the ability of such measurements by upcoming experiments to constrain cosmology and astrophysics.
