Title: Search for evidences beyond the concordance model of cosmology
Speaker: Arman Shafieloo

Abstract:  In the standard model of cosmology, dark energy and dark matter constitute about 96% of the total energy budget of the cosmos. The nature of both dark energy and dark matter are still unknown to us but we know that they exist. I go through the discoveries and the developments that informed us about their presence and I discuss about how we are trying to learn more about these mysterious components of our universe using astronomical observations and high performance computations.

Title:A unique and observable imprint of inflation
Speaker: Robert Caldwell

Abstract: Inflation is the leading paradigm for the physics of the early Universe. In the inflationary scenario, the size of the Universe grows exponentially, stretching quantum fluctuations to macroscopic scales. These fluctuations are the seeds of the large scale structures of the Universe, observed in the distribution of galaxies and in the cosmic microwave background. In this talk, I will review the inflationary paradigm and explain how quantized fluctuations of the gravitational field are produced and leave a unique signature in the cosmic microwave background. I will also present recent results which consider the possibility that such a primordial gravitational wave background has a net handedness.

Title: Primordial Gravitational Waves
Speaker: Robert Caldwell

Abstract:  We consider the possibility of a spectrum of gravitational waves as a relic from the early Universe. Detection of these waves could reveal information about the earliest moments of the hot Big Bang, as well as the composition and structure of the Universe. In this talk, we review several scenarios for the emission of primordial gravitational waves and the methods of detection. In particular, we highlight new geometries for gravitational wave detectors that could enhance the sensitivity to these elusive waves.
