The Bad Astronomer said “sychotron radiation”

I looked that up and the closest I got was synchrotron radiation.

Synchrotron radiation gives me a point to start looking for science that’s been done to answer questions like mine about where all that radiation comes from and why, while keeping some distance from the fringe stuff that blames it all on legendary lightning bolts of Thor that Velikovsky reinterpreted some old legends as being about, or blames it on artists’ conceptions of “black holes” and their spirals and jets without having any explanation of how they work.

MoeHammered: Did you mean that red image with the prominent nose in profile in the lower section, and the hint of a shock of red hair at the top, and the left eyebrow in the center of the image? And with Phil looking towards the East / right side of the screen?

No, can’t say I did.

Ivan.

Pareidolia Alert:
Did anybody else notice that the radio wave image looks a bit like BA Phil poking his head around a corner? The top half, especially.

This blog is one of my faves, and this post is another reason why.

Thanks, Phil!

Howdy Doody, your initial assumption isn’t correct. Radio waves can be emitted in many different ways, as can X-rays. Kinetic energy is just one way, but there is also sychotron radiation. The jets from black holes have a vast amount of kinetic energy; they are travelling at very nearly the speed of light when they leave the center of the cluster. They do slow down, but the emission of the radio waves isn’t tied to their temperature.
