| 14:00 - 15:00 Weekly Seminar HEPCo Group Constraining local primordial non-Gaussianity with galaxy surveys School PHYSICS Date and time Tuesday, 7th November 2023 (16th of Aban, 1402), 2:00 pm (Tehran zone) Link https://www.skyroom.online/ch/schoolofphysics/highenergyseminar Abstract 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 the sq ... |
