Why do we look for the pion bump in SEDs to try to understand if a site is freshly accelerating CRs?

Because the pion bump is a signature of proton-proton collisions and 90% of cosmic rays are protons!

Because the pion bump is the signature of inverse Compton scattering, which is a direct result of CR production!

Because shock-cloud interactions decay into pions, which then generate CRs.

None of the above

Why aren't we able to determine the particle population from our SED modeling alone?

Because the Earth is flat and all of this is false.

Because electrons and positrons embed themselves in emission across the spectrum, making it hard to disentangle.

Both A and B.

Because all of the models can explain the data we have so far.

What does SED stand for?

Super electronic device.

Spectacular evolutionary demons.
