Radiation
movie_from_modes.mpgThe gravitational radiation from an equal mass binary black hole system, as seen side-on from a large distance. The central sphere, within which there is no radiation denotes the smallest sphere where the Weyl tensor component Psi4 is extracted in the numerical domain. This visualization was carried out using a new spectral interpolator that was built to reconstruct the volume Psi4 data from just the extracted modes of Psi4 on various large spheres. The rendering involves ray-tracing.
movie_fine_modes.mpgGravitational waves as a pseudocolor plot. This shows the radiation on all the extraction spheres available in the numerical domain. The black holes can be seen as small white spheres in the centre. The simulation corresponds to a non-spinning system as in the previous case but with a mass ratio of 0.6. THe simulation was carried out using the EinsteinToolkit.
movie_q0p667_2098x2021_top_solid.mp4A top-view, contour plot of the strength of radiation Psi4. THe junk-radiation phase in the initial frames can clearly be seen. This corresponds to a q=0.667 system that is non-spinning. The simulation was carried out using the EinsteinToolkit.
movie_top_psi4_with_tidal_deformations.mpgA top view of gravitational radiation along with black holes. This is similar to the above video, but also shows the black holes. The dominant quadrupolar deformations can clearly be seen.
movie_rad_syn_volume_transfer.mpgSynthetic scalar radiation in a volume. This video employs state of the art methods developed by the author to carry out ray tracing and volume rendering of radiation in a volume.
