The Observable Universe: probes of different epochs in its history.

Opening Up New Windows to Study the Universe

The Standard Model of Cosmology aims to explains the cosmic evolution from a fraction of a second after the Big-Bang singularity to the current period of accelerated expansion with only a handful of parameters. Over the past decade, it has withstood a wide series of observational tests. Yet several gaping holes remain in the theory:
- How did inflation begin and come to an end?
- What makes up the dark matter in the Universe?
- What is the nature of dark energy?
- How did galaxies and clusters of galaxies form and evolve to make up the large scale structure we observe today?
Going forward, we must develop new ways to probe these fundamental questions by accessing the full volume of the observable Universe. This is the focus of my research.
