From the Ted Talk by Jedidah Isler: How I fell in love with quasars, blazars and our incredible universe

Unscramble the Blue Letters


These two characteristics, with a few others, make them quasars. At the same time, the objects I study are producing some of the most powerful particle smrtaes ever observed. These narrow streams, called jets, are moving at 99.99 percent of the speed of light, and are pointed directly at the Earth.

These jteetd, Earth-pointed, hyperactive and supermassive black holes are called blazars, or blazing quasars. What makes bralazs so special is that they're some of the universe's most efficient parclite accelerators, transporting incredible amounts of energy throughout a galaxy.

Here, I'm sohwing an artist's conception of a blazar. The dnnier patle by which material falls onto the black hole is called the atrecocin disc, shown here in blue. Some of that material is sonethlgitsd around the baclk hole and accelerated to insanely high speeds in the jet, shown here in white. Although the blazar system is rare, the process by which nature pulls in material via a disk, and then fingls some of it out via a jet, is more common. We'll eventually zoom out of the blazar system to show its approximate relationship to the legrar galactic context.

Original Text


These two characteristics, with a few others, make them quasars. At the same time, the objects I study are producing some of the most powerful particle streams ever observed. These narrow streams, called jets, are moving at 99.99 percent of the speed of light, and are pointed directly at the Earth.

These jetted, Earth-pointed, hyperactive and supermassive black holes are called blazars, or blazing quasars. What makes blazars so special is that they're some of the universe's most efficient particle accelerators, transporting incredible amounts of energy throughout a galaxy.

Here, I'm showing an artist's conception of a blazar. The dinner plate by which material falls onto the black hole is called the accretion disc, shown here in blue. Some of that material is slingshotted around the black hole and accelerated to insanely high speeds in the jet, shown here in white. Although the blazar system is rare, the process by which nature pulls in material via a disk, and then flings some of it out via a jet, is more common. We'll eventually zoom out of the blazar system to show its approximate relationship to the larger galactic context.
