Numerical Relativity strives to solve the field equations of General Relativity in conjunction with equations of magnetohydrodynamics using supercomputers. These numerical simulations are essential tools for accurately modeling mergers of black holes or neutron stars, collapse of massive stars (possibly resulting in supernovae), and accreting black holes (in X-ray binaries or in galactic cores). Recent observations of nearly a hundred gravitational-wave (GW) signals from coalescing binaries of black holes, and multi-messenger observations of coalescing neutron stars have firmly established the role of Numerical Relativity in astrophysics. Such high-energy astrophysical phenomena are prime targets for the upcoming GW-, electromagnetic- and neutrino observatories. This two-week summer school, jointly organized by ICTS and Raman Research Institute, is part of our annual summer school series on GW astronomy. The lectures will be organized into four graduate-level mini courses:Courses: Num...
