DESCRIPTION:ABSTRACT:With the advent of Gravitational Wave (GW) astronomy 
 a new door into learning about properties of matter has been opened. In pa
 rticular\, gravitational waves coming from a first order phase transitions
  are expected to be detectable by next generation experiments. These are a
 ssumed to proceed via the nucleation\, expansion and collision of bubbles.
  An accurate prediction of the spectrum implies computing out-of-equilibri
 um properties of quantum field theories\, which are challenging even at we
 ak coupling. This offers a golden opportunity for holography to make an im
 pact on astrophysics and cosmology. In this talk I will review recent prog
 ress in the context of cosmological phase transitions\, including a possib
 le alternative mechanism of GW emission\, and neutron star mergers.
