Could there be an undetected inner planet near the stability limit in Kepler-1647? Abstract: Kepler-1647b is the most recently discovered planet that transits two stars, e.g., a circumbinary planet (CBP). Due to its large orbital separation, Kepler-1647b stands out from the rest of the Kepler CBPs, which mostly reside on much tighter orbits near … Continue reading "CRA Cosmic Coffee: Ziqian Hong"
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 … Continue reading "CRA seminar: Dr. Yan-Fei Jiang (University of California Santa Barbara)"

Title: Gravitational Waves: Using Merger to Understand Ringdown Abstract: With the advent of gravitational wave astronomy, we have newly found access to a wealth of knowledge in the form of gravitational waves. Scientists are working hard to extract as much information as possible from each of the ten binary black hole coalescences (and one … Continue reading "CRA Cosmic Coffee: Deborah Ferguson"
Title: Intermittent AGN feedback in galaxy clusters driven by cold gas accretion Abstract: Recent observations of cool core clusters provide evidence that the presence of cold, atomic and molecular gas in their centers is more common than previously expected. This finding has important implications for the fueling of and feedback from the supermassive black holes … Continue reading "CRA Cosmic Coffee: KwangHo Park"
