[B][URL=http://gammaray.nsstc.nasa.gov/gbm/publications/preprints/gbm_ligo_preprint.pdf]GBM observations[/URL] at the time of the Laser Interferometer Gravitational-wave Observatory (LIGO) event GW150914 reveal the presence of a weak transient source above 50 keV, 0.4 s after the GW event was detected, with a false alarm probability of 0.0022. This weak transient lasting 1 s does not appear connected with other previously known astrophysical, solar, terrestrial, or magnetospheric activity. Its localization is ill-constrained but consistent with the direction of GW150914. The duration and spectrum of the transient event suggest it is a weak short Gamma-Ray Burst arriving at a large angle to the direction in which Fermi was pointing, where the GBM detector response is not optimal.[U] If the GBM transient is associated with GW150914, this electromagnetic signal from a stellar mass black hole binary merger is [I]unexpected[/I].[/U] From our measurement of the fluence seen by GBM, we calculate a luminosity in hard X-ray emission between 1 keV and 10 MeV of 1.8*10^49 erg/s. The observation by Fermi GBM encompasses 75% of the probability map associated with the LIGO GW event localization at the time the GW event was detected. Assuming the two events have a common origin...[/B]

В заявленном понятна корреляция между гамма-излучением и гравитацией.

Поскольку полученная частота гравитационного излучения всего в 100 раз менее частоты самого низкочастотного радиоизлучения в 3000 Гц, [URL=http://journals.aps.org/prl/abstract/10.1103/PhysRevLett.116.061102]The signal sweeps upwards in frequency from 35 to 250 Hz[/URL], а энергия гравитационного взаимодействия на десятки порядков менее ЭМ, то полагая, что здесь зарегистрирован фронт гравитонов, модулирующих колебания напряжённости поля гравитационного взаимодействия, постольку энергия гравитонов соответственно менее энергии фотонов. Последнее, вообще говоря, соответствует заявленной иерархии.
