Title: Dynamical Assembly of Black Hole Binaries in Dense Star Systems Abstract: The discovery of merging black hole (BH) binaries by the LIGO and Virgo experiments has initiated the era of gravitational wave (GW) astrophysics. Detailed comparisons between theoretical and observed waveforms have already tested classical general relativity, and placed stringent constraints on alternative theories … Continue reading "CRA Seminar (Dr. Nicholas Stone, Columbia University)"

Title: CHIME - the Canadian Hydrogen Intensity Mapping Experiment Keith Vanderlinde (University of Toronto) URL: http://dunlap.utoronto.ca/~vanderlinde/ ABSTRACT: Among the great surprises of modern cosmology was the discovery of Dark Energy, which dominates the energy budget of the Universe and is driving the acceleration of its expansion rate. Decyphering its properties and nature will require novel … Continue reading "CRA Seminar (Dr. Keith Vanderlinde, University of Toronto)"

3D Radiation Magneto-hydrodynamic Simulations of Accretion Disks around Supermassive Black Holes Abstract: Black hole accretion disks convert the gravitational energy of accreted gas to photons and produce varies observational phenomena of AGNs. First principle calculations of black hole accretion disks for a wide range of accretion rates are not only important for understanding various observational … Continue reading "CRA seminar: Dr. Yan-Fei Jiang (University of California Santa Barbara)"
