High energy gamma ray "magic" project

[fred2014]

I was watching the documentary about this project based on La Palma with

the "magic" telescopes last night.

 

Am I right in believing that the gamma rays being monitored are of 2 different

energy levels and if so could someone explain (as simply as possible)

how the 2 states come to be - and define the differences in practical terms

if possible.

 

or perhaps correct me if I have misconstrued something?

 

thanks

I am not sure what the "two different energy levels" refers to (there are a wide range of energy levels detected).

Thanks strange - I had the first link but didn't think to go to wikipedia.

 

The 2 levels mentioned in the program turn out to be 2 ranges accordig to the

second paragraph in the "observations" section on wikipedia so that clears that up for me.

 

I expect either I miss-heard the documentary or it was oversimplified for their script a little.

 

Still ... Very interesting work.
