The large collecting area, high spectral and spatial resolution of a mission such as Athena can provide the breakthrough diagnostic ability necessary for developing a robust physical understanding of AGN jet feedback.
This will be achieved via exquisitely detailed studies of low-redshift groups and clusters, and via the removal of biases through dramatically improved statistics for population studies of jet feedback in groups and clusters to z~1.
