Dear All,
This week’s C&G meeting will take place on Wednesday, 7th November with a seminar and FIKA.
Date: November 7, Wednesday
Time: 13:15
Place: C6: 1038
Christiane Lorenz from the Department of Physics, University of Oxford will give a seminar. Christiane is supervised by Pedro Ferreira,
Erminia Calabrese and David Alonso. Her main aim is to test neutrino models
with cosmological observations, for example with observations of the
cosmic microwave background and of the large scale structure of the Universe.
Title: Robust neutrino mass measurements in cosmology
Abstract:
In this talk, I will present studies of the model-dependence of cosmological
neutrino mass constraints. In particular, I will focus on two phenomenological
parameterizations of time-varying dark energy (early dark energy and barotropic
dark energy) that can exhibit degeneracies with the cosmic neutrino background over extended periods of cosmic time. Moreover, I will show how the combination of
multiple probes across cosmic time can help to distinguish between the two components.
In addition, I will discuss how neutrino mass constraints can change in extended neutrino
mass models, and how current tensions between low- and high-redshift cosmological data
might be affected in these models.
See you all on Wednesday!
Jens & Raghu
