At z=1-3, massive post-starburst galaxies show X-ray AGN detection rates (6.2 +/- 1.5 per cent) and average luminosities similar to passive galaxies and below star-forming galaxies, providing no evidence that an AGN excess accompanies the quenching event.

No evidence for excess AGN activity in recently quenched massive galaxies at cosmic noon
At z=1-3, massive post-starburst galaxies show X-ray AGN detection rates (6.2 +/- 1.5 per cent) and average luminosities similar to passive galaxies and below star-forming galaxies, providing no evidence that an AGN excess accompanies the quenching event.
