Description
With the advent of GW astronomy, a new exciting window into studying matter has been opened. It is then crucial to perform a search for possible GW sources. In this talk I will present two new sources of GW emission from first order phase transitions: the spinodal instability and phase transitions in neutron star mergers. The former is relevant in the context of cosmology, when bubble nucleation is largely suppressed. The latter has become an exciting possibility in the light of recent results and would produce a potentially detectable signal in the MHz range.
