We speculate on the possible scenario for the formation of a gamma-ray burst accompanied by the GW signal. Our model invokes a close binary system consisting of a massive star and a black hole, which leads to triggering of a collapse of the star's nucleus, formation of a second black hole, and finally to the binary black hole merger. For the most-likely configuration of the binary spin vectors with respect to the orbital angular momentum in the GW150914 event, the recoil velocity acquired by the final black hole through gravitational waves emission allows it to take only a small fraction of matter from the host star. The gamma-ray burst is produced on the cost of accretion of this remnant matter onto the final black hole. The moderate spin of the final black hole accounts for the gamma-ray burst jet to be powered by a weak neutrino emission rather than the Blandford-Znajek mechanism, and hence explains low power available for the observed GRB signal.

Whereas Maxwell's Electrodynamics was the culmination of a long series of experiments by Franklin, Priestley, Coulomb, Volta, Ampere and Faraday, Einstein produced General Relativity from a few guiding principles such as Causality and the Principle of Equivalence. The discovery of dark energy as a dominant force in Astronomy makes us consider the gravitational forces not merely due to mass but also those due to stress and due to currents of energy, currents of momentum and of currents of angular momentum. We do this by assuming Einstein's theory and working out the results of thought experiments analogous to the real experiments made in electricity. Analogies with Electricity are discussed and Bonnor's beautiful 1969 paper on the gravity of a light ray is analysed to give an alternative derivation of the light-bending formula.

Short summary of the "13th INTEGRAL BART Workshop IBWS" which was organized in Karlovy Vary, Czech Republic on April 18-21, 2016. During that workshop on "Small satellite day" the first Czech satellite VZLUSAT1 was presented as well as two concepts for the Czech BRITE (one with an X-ray and UV detector and a second one with an X-ray detector). The main goal of the workshop was to bring together scientific experimenters and payload providers with the small satellite designers and realizers and high-energy variability astrophysicists.

The first detections of gravitational waves from binary black hole mergers have opened up new opportunities and challenges in astrophysics and fundamental physics. I will describe these recent discoveries and discuss advances in the analysis and interpretation of gravitational-wave observations. I will focus on my group's efforts to extract the astrophysical evolution of massive stellar binaries from observations of gravitational waves emitted during mergers of the stellar remnants.
