Some of the universe's most energetic and mysterious light shows, long gamma-ray bursts, could be generated after dense dead stars collide to create infant black holes surrounded by a natal disk of ...

A bright flash of gamma rays from the constellation Boötes that lasted nearly one minute came from a kilonova, as we described in a new paper. This finding challenges what astronomers know about some ...

Three unusually long-lasting stellar explosions discovered by NASA’s Swift satellite represent a previously unrecognized class of gamma-ray bursts (GRBs). Two international teams of astronomers ...

While the origin of gamma-ray bursts — the most powerful explosions known in the universe — remains a mystery, scientists say that the two major varieties, long and short bursts, arise from different ...

Volatility is an asset class that trades under different regimes. During very calm periods with more economic certainty and stability, volatility trades at very low levels. When corporate earnings ...
