SUMMARY:The triggering mechanisms of powerful radio galaxies: mergers and i
 nteractions.
DESCRIPTION:The triggering mechanisms of powerful radio galaxies: mergers a
 nd interactions.\nDr. Cristina Ramos Almeida\n\nDespite speculation that b
 oth starburst and nuclear activity in galaxies may be intimately linked vi
 a the common triggering mechanism of mergers and interactions, very little
  is known about the true nature of the link. Thus, the role of AGN in the 
 formation and evolution of galaxies is still not well established. I will 
 present deep Gemini/GMOS imaging observations which are used to investigat
 e the triggering mechanism(s) in a complete sample of radio-loud AGN for w
 hich, uniquely, we have quantified the level of both the AGN and star form
 ation activity. I will show results on the proportion of powerful radio ga
 laxies triggered in galaxy mergers and also on the link between the degree
  of star formation/AGN activity and the interaction status of the host gal
 axies.
