Jet-ISM interaction:
● Star formation?
● Galaxy growth
● Why elliptical?
● Why so many of them?
What did we do?

Is there a better way?R. Sutherland, G. V. Bicknell 2008
For relativistic particle assuming equipartition
R=0.18 LS

Summary
● GPS are found in all kind of host galaxies
● Jet-efciency consistent with MAD disk scenario
● Overluminous in radio→ higher radiative efciency
