Investigating AGN feedback using Integral-field spectroscopy

Cristina S. Fernandes
Oxford University

The shape of the luminosity function of galaxies is still not entirely understood. In particular, there are less bright galaxies than would be expected from semi-analytical models based on the mass function of dark matter halos. This points to the fact that there must be some sort of mechanism preventing star formation on this very massive galaxies. AGN feedback in the form of powerful outflows, jets, gas heating and gas expulsion, are taken as strong candidate mechanisms. In this talk I will show how the recent technique of integral-field spectroscopy allied to radio observations can help unveil details on the interaction between the radio jets and the ionised gas within and surrounding high redshift radio galaxies.
