Title: Simulating Lyman-Alpha Sources in the Epoch of Reionization Abstract: Radiation from the first stars and galaxies initiated the dramatic phase transition marking an end to the cosmic dark ages. The emission and absorption signatures from the Lyman-alpha (Lyα) transition of neutral hydrogen have been indispensable in extending the observational frontier for high-redshift galaxies into … Continue reading "Aaron Smith (UT-Austin): Simulating Lyman-Alpha Sources in the Epoch of Reionization"

Measuring the polarization state of gravitational waves Alternative theories of gravity predict additional polarization states to the two tensor modes of general relativity. LIGO/Virgo have provided the first observation constraints on polarization. Pulsar Timing and Astrometry can be used to set even stronger constraints. I will give an update of the current status of polarization … Continue reading "CRA Seminar: Neil Cornish (Montana State)"
