Gravity Group Seminar, Will Coulton (Princeton University) "Cosmology and astrophysics from the bispectrum"
Cosmology and astrophysics from the bispectrum
The three point function of the cosmic microwave background (CMB) is an ideal place to study CMB secondary sources as there is no noise bias and CMB secondaries are the dominant contribution. In this talk I will discuss my work measuring the bispectrum from radio galaxies, dusty star forming galaxies and thermal Sunyaev Zel'dovich sources in ACT and Planck maps. I will then discuss what we hope to learn from the bispectrum with ongoing surveys.
