Workshop “Gravity Falls : Implication of gravitationnal waves observation on modified gravity theories”

The goal of this workshop, organised the 10th of December by the Paris Center of Cosmological Physics, the Laboratoire Astroparticule et Cosmologie and the GdR “ondes gravitationnelles”, is to explore the implications of past and future gravitational waves observations on modified gravity theories. During the session of the morning review talks about theory and past and future gravitational-wave observations will […]

All in the Family: Kin of Gravitational Wave Source Discovered

New observations suggest that kilonovae—immense cosmic explosions that produce silver, gold and platinum—may be more common than thought  On October 16, 2017, an international group of astronomers and physicists excitedly reported the first simultaneous detection of light and gravitational waves from the same source—a merger of two neutron stars. Now, a team that includes several University of Maryland astronomers has identified […]
