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

These disks are MAD!!!

Summary

● GPS are found in all kind of host galaxies

● Jet-efciency consistent with MAD disk scenario

● Overluminous in radio→ higher radiative efciency
