The FRII Broad Line Seyfert 1 Galaxy: PKSJ 1037-2705

TL;DR

This paper presents PKSJ 1037-2705 as a unique broad-line Seyfert 1 galaxy with a weak accretion flow but a powerful jet, challenging assumptions about the relationship between accretion and jet power.

Contribution

It provides one of the first documented cases of a kinetically dominated broad-line AGN with weak accretion luminosity but strong jet activity.

Findings

Jet kinetic luminosity exceeds thermal accretion luminosity.

Weak accretion flow with prominent broad emission lines.

Active relativistic jet indicated by blazar emission.

Abstract

In this article, we demonstrate that PKSJ 1037-2705 has a weak accretion flow luminosity, well below the Seyfert1/QSO dividing line, weak broad emission lines (BELs) and moderately powerful FRII extended radio emission. It is one of the few documented examples of a broad-line object in which the time averaged jet kinetic luminosity, $\bar{Q}$, is larger than the total thermal luminosity (IR to X-ray) of the accretion flow, $L_{bol}$. The blazar nucleus dominates the optical and near ultraviolet emission and is a strong source of hard X-rays. The strong blazar emission indicates that the relativistic radio jet is presently active. The implication is that even weakly accreting AGN can create powerful jets. Kinetically dominated ($\bar{Q}>L_{bol}$) broad-line objects provide important constraints on the relationship between the accretion flow and the jet production mechanism.
