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"
Hunting for Monsters! Active supermassive black holes identification and their host galaxies’ physical properties Active galactic nuclei (AGN) are powered by the accretion activity of supermassive black holes residing at the centers of galaxies. While observations propose that growth of AGN and galaxies are globally tied, I investigate whether this connection exists in individual galaxies. I … Continue reading "Dr. Mojegan Azadi (Harvard-Smithsonian Center for Astrophysics, Cambridge)"
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)"
