“…For CCSNe at distances D 1 Mpc, an observed coincident neutrino signal is highly unlikely [81][82][83]. In this case, the time of core collapse must be inferred based on estimates of the explosion time, explosion energy, and the radius of the progenitor.…”

We present results from a search for gravitational-wave bursts coincident with two core-collapse supernovae observed optically in 2007 and 2011. We employ data from the Laser Interferometer Gravitational-wave Observatory (LIGO), the Virgo gravitational-wave observatory, and the GEO 600 gravitational-wave observatory. The targeted core-collapse supernovae were selected on the basis of (1) proximity (within approximately 15 Mpc), (2) tightness of observational constraints on the time of core collapse that defines the gravitational-wave search window, and (3) coincident operation of 6 at least two interferometers at the time of core collapse. We find no plausible gravitational-wave candidates. We present the probability of detecting signals from both astrophysically well-motivated and more speculative gravitational-wave emission mechanisms as a function of distance from Earth, and discuss the implications for the detection of gravitational waves from core-collapse supernovae by the upgraded Advanced LIGO and Virgo detectors.

This manuscript presents information for all supernovae discovered by the All-Sky Automated Survey for SuperNovae (ASAS-SN) during 2015, its second full year of operations. The same information is presented for bright (m V ≤ 17), spectroscopically confirmed supernovae discovered by other sources in 2015. As with the first ASAS-SN bright supernova catalogue, we also present redshifts and near-ultraviolet through infrared magnitudes for all supernova host galaxies in both samples. Combined with our previous catalogue, this work comprises a complete catalogue of 455 supernovae from multiple professional and amateur sources, allowing for population studies that were previously impossible. This is the second of a series of yearly papers on bright supernovae and their hosts from the ASAS-SN team.

We report gravitational-wave (GW) signatures based on two-dimensional (2D) neutrino-radiation hydrodynamics simulations of core-collapse supernovae (CCSNe). Using multiple progenitor models, we present systematic analysis of the GW emission from the self-consistent 2D models. We find that the total GW energies emitted during the simulation become higher for models with progenitors' high compactness. This is because the high compactness leads to more energetic explosions, where non-spherical hydrodynamic motions associated with neutrino-driven convection and the StandingAccretion-Shock-Instability develop much more violently. On the other hand, we show that the GW energies become smaller for high-compactness models that fail to explode by the neutrino-driven mechanism. This is because non-spherical motions in the postbounce core get gradually weaker with the decreasing mass accretion rate to the proto-neutron star, which leads to the smaller GW amplitudes in the long postbounce evolution. We discuss the detectability of the GW signals from both the successful and unsuccessful models using the advanced GW detectors including LIGO and KAGRA.
