Description

Paul La Plante from the University of Pennsylvania, Philadelphia will be the featured speaker at an upcoming astronomy colloquium. His talk is titled, "Unveiling Cosmic Dawn with Simulation and Experiment."

Cosmic dawn, the portion of the Universe's history when the first stars and galaxies ignited nearly 13 billion years ago, represents a new and exciting frontier in cosmology. Currently, little is know about these early galaxies, or the state of the intergalactic medium (IGM) surrounding them. Numeric simulations including hydrodynamics and radiative transfer have provided valuable insight to the interplay between galaxies and the IGM. At the same time, radio interferometers, such as the Hydrogen Epoch of Reionization Array (HERA), are being constructed to provide observational information about this epoch. In this talk, La Plante will discuss how upcoming results from HERA can provide information about high-redshift galaxies, and how to incorporate the results into simulations. He will also discuss prospects for cross-correlating HERA data with observations of the CMB, adding further knowledge about the early Universe.
