Lund Observatory Seminar Series
Title: Cosmological Conundrums
Speaker: Joe Liske, Universität Hamburg
Over the course of the past several decades, Observational Cosmology
has made great progress in establishing a standard model of cosmology:
LambdaCDM. This model successfully reproduces and explains a vast
array of cosmological observations. These successes notwithstanding,
LambdaCDM continues to be plagued by several rather obvious and
fundamental issues, including: What is Dark Matter? What causes the
acceleration of the expansion of the Universe? Why do different types
of measurements of the current expansion rate yield different results?
In this personally biased talk I will review some aspects of the
current status of these issues and introduce some of the new
observational facilities that will be brought to bear on them.
Tea and coffee will be served outside the lecture hall after the talk.
