Numerical simulations of neutron stars and black holes provide insights into the possible structure of gravitational wave signals and into other astrophysical phenomena.
The figures and the animation show the coalescence of two orbiting black holes as detected by the Advanced LIGO and Advanced Virgo observatories on the 14th of August 2017. [more]
The video and the images show a numerical simulation of the gravitational-wave event GW170104 associated to the third binary black-hole coalescence detected by LIGO. [more]
In this model, a smaller and a large black hole move linearly towards each other and collide head-on. The smaller black hole moves faster, has a high downward momentum and emits strong gravitational waves downwards. [more]
