Based on our three-dimensional hydrodynamic simulations of core-collapse supernovae (CCSN) including spectral neutrino transport, we present the gravitational-wave signatures emitted from a wide variety of SN progenitors. We also discuss how we can learn about the supernova mechanism by taking a correlation analysis between the gravitationa-wave and neutrino signatures particularly in the case...

The next galactic core-collapse supernova (CCSN) has already
exploded, and its electromagnetic waves, neutrinos, and gravitational
waves may arrive at any moment. We present a
method for detecting GWs from CCSNe with a network of ground-based laser
interferometers, triggered by electromagnetic or neutrino observations.
Using such triggers, the uncertainty in the signal arrival time...

Detecting the electromagnetic counterpart of a neutron star binary merger increases the amount of information that can be extracted from the gravitational wave signal. Material ejected dynamically during the first ~10 milliseconds after the merger is a known source for this electromagnetic emission. A separate channel for mass ejection arises from the viscous evolution of the remnant accretion...

The Advanced LIGO and Virgo gravitational wave interferometers are expected
to begin science operations in the second half of this decade. Based on the predicated
rates for compact binary mergers and the strain sensitivity, the Advanced LIGO / Virgo
network is expected to make the first direct observations of gravitational waves. In
addition, some sources of gravitational radiation are...

Despite decades of effort, the explosion mechanism of core-collapse supernovae is still not well understood. Spherically-symmetric models fail to explode, suggesting that multi-dimensional effects are of crucial importance. Studies in axisymmetry (2D) reveal that the standing accretion shock instability (SASI) and neutrino-driven convection are pivotal ingredients for successful explosions....
