Title: A multi-observatory X-ray approach to characterize heavily obscured AGNs According to the different models of Cosmic X-ray Background (CXB), the diffuse X-ray emission observed in the 1 to ~200-300 keV band, is mainly caused by accreting supermassive black holes, the so-called active Galactic Nuclei (AGN). Particularly, at the peak of the CXB (~30 keV) … Continue reading "CRA Seminar: Dr. Stefano Marchesi (Clemson University)"
Monte Carlo Simulation and Balloon-Borne Observation of Energetic Radiations and Electromagnetic Fields from Thunderstorms and Lightning Mahdi Bagheri Space Science Center and Physics Department, University of New Hampshire Abstract: Lightning is one of the most energetic geophysical phenomena, producing the brightest light and loudest sound commonly occurring on Earth. Because of its high … Continue reading "CRA Seminar: Mahdi Bagheri (University of New Hampshire)"
