Constraining local primordial non-Gaussianity with galaxy surveys
Date and time
Tuesday, 5th September 2023 (14th of Shahrivar, 1402), 2:00 pm (Tehran zone)
While early studies of the cosmic microwave background and large-scale structure suggested that primordial fluctuations are both Gaussian and scale-invariant, some alternative classes of inflationary models predict different levels of non-Gaussianities in the primordial gravitational field. Local primordial non-Gaussianity (PNG) generates a primordial bispectrum, which peaks in ...
