Title: | Black Hole Imaging: First Results and Future Vision |
Meeting-ID: 977 2640 8385Kenncode: 291628In April 2017, the Event Horizon Telescope (EHT) carried out a global Very Long Baseline Interferometry (VLBI) observing campaign at a wavelength of 1 mm that led to the first resolved image of a supermassive black hole. For the 6.5 billion solar mass black hole in the giant elliptical galaxy M87, the EHT estimated the spin orientation and constrained models of accretion on Schwarzschild radius scales. This work relied on two decades of technical advances in ultra-high resolution interferometry and theoretical General Relativistic Magnetohydrodynamic (GRMHD) simulations. This talk will review these advances and recent new EHT results. We will also look to the next decade when a next-generation EHT (ngEHT) that doubles the number of participating radio dishes in the VLBI network will enable time-lapse movies of M87 that link the black hole to the relativistic jet it powers. For SgrA*, the Galactic Center black hole that evolves on time scales 1000 times faster, ngEHT will produce real-time video. |

Title: | Spreading dynamics of COVID-19 and its mitigation |
Meeting-ID: 977 2640 8385Kenncode: 291628How can we infer the spreading of activity if only a fraction of the system is observed? And how can we then infer the spread of SARS-CoV-2? We recapitulate the basic principles of spreading dynamics, its role in shaping collective properties, and its ability to describe COVID-19. We show how COVID-19 is mitigation by test-trace-isolate strategies, and derive a metastable state, which could greatly facilitate stability. Last but not least, we discuss spreading dynamics in neural networks and its role in computation. |
