Fall 2023 Gundzik Colloquium
Revealing the history and future of the universe with the Cosmic Microwave Background
Measurements of the cosmic microwave background (CMB) serve as a potent tool for understanding the genesis, composition, and development of our Universe. The rate at which we are capable of mapping the CMB is outpacing Moore’s law, increasing by about an order of magnitude every five years. This rapid development has led to remarkable scientific discoveries such as confirming the geometry of our universe, refining theories of its primordial state, and solidifying our grasp on the Lambda-CDM model. Observations from the current wave of experiments, like POLARBEAR, and the Simons Array are delivering tighter cosmological constraints. Looking forward, initiatives like the Simons Observatory will illuminate phenomena like inflation and alternatives, offer insights into dark energy, dark matter, and neutrino masses.
In this talk, I will discuss results from POLARBEAR and how this experiment is facilitating the next generation of experiments, including the Simons Observatory.
