This Friday, Apr 12th, The UQ Physics Colloquium is hosting Dr. Florian Beutler, Senior Research Fellow from the University of Portsmouth. Dr. Beutler will talk about different ways to use galaxy redshift surveys to study sum of neutrino masses as well as model early Universe.


The talk will be given at 11 am in Parnell (07) Rm 222.


Everyone is welcome to join.


Abstract: In this talk, I will present various ways in which we can use galaxy redshift surveys to constrain fundamental physical models. This year the DESI experiment will launch, collecting a dataset of about 50 million galaxies and Quasars. Using observables like Baryon Acoustic Oscillations and Redshift-space distortions we can use this dataset to measure the sum of the neutrino masses and the number of neutrino species as well as test models of dark energy and modified gravity. Moreover, we can test models of the very early Universe (inflation) through primordial non-Gaussianity and primordial oscillations. The multitude of upcoming survey experiments (LSST, Euclid, PFS, SPHEREx, DESI, WFIRST) offers exciting prospects to put the standard model of cosmology (LCDM) to the test.
