Abstract: On 14 September 2016, the Laser Interferometer Gravitational-WaveObservatory (LIGO) detected the first gravitational wave signal everdirectly observed. This observation also represents the first directobservation of a black-hole binary and has opened up a qualitatively newwindow to the universe.

Gravitational Lensing and BH Shadows Workshop

In the wake of the detection of gravitational waves from black hole mergers and at the door step of an era of precision electromagnetic observations of the horizon scale for black hole candidates, in particular with the Event Horizon Telescope, the gravitation groups at Aveiro University, Gr@v, and at IST-Lisbon, Grit, will organize a two days workshop on Gravitational Lensing and Black Hole Shadows, held at the University of Aveiro (Portugal), on the 3rd and 4th of November 2016.
