Reconciling AGN-star formation, the Soltan argument, and Meier's paradox

TL;DR

This paper presents a theoretical framework linking AGN activity, star formation, and jet power evolution, explaining recent observations and resolving the Meier Paradox by integrating jet-induced star formation with black hole spin and accretion dynamics.

Contribution

It introduces a novel model coupling jet-induced star formation with black hole spin and accretion, explaining the cosmological evolution of AGN properties and resolving existing paradoxes.

Findings

Star formation is enhanced at lower optical luminosity in radio loud quasars.

Jet power peaks at higher redshift than accretion power, consistent with observations.

Predicts a family of radio quiet AGN with rapidly spinning black holes at low redshift.

Abstract

We provide a theoretical context for understanding the recent work of Kalfountzou et al (2014) showing that star formation is enhanced at lower optical luminosity in radio loud quasars. Our proposal for coupling the assumption of collimated FRII quasar jet-induced star formation with lower accretion optical luminosity, also explains the observed jet power peak in active galaxies at higher redshift compared to the peak in accretion power, doing so in a way that predicts the existence of a family of radio quiet AGN associated with rapidly spinning supermassive black holes at low redshift, as mounting observations suggest. The relevance of this work lies in its promise to explain the observed cosmological evolution of accretion power, jet power, and star formation, in a way that is both compatible with the Soltan argument and resolves the so-called `Meier Paradox'.
