  We present gravitational wave and neutrino signatures obtained in our first
principle 3D core-collapse supernova simulation of 15M non-rotating progenitor
with Chimera code. Observations of neutrinos emitted by the forming neutron
star, and gravitational waves, which are produced by hydrodynamic instabilities
is the only way to get direct information about the supernova engine. Both GW
and neutrino signals show different phases of supernova evolution.
