Suzaku Observations of the Radio Galaxy 3C 33

TL;DR

This study uses Suzaku X-ray observations to analyze the absorption, reflection, and jet production mechanisms in the radio galaxy 3C 33, revealing a lack of expected reflection features and providing insights into its accretion environment.

Contribution

First detailed Suzaku X-ray analysis of 3C 33 revealing absence of reflection features, informing models of jet production and accretion in radio galaxies.

Findings

No relativistically blurred Fe Kα line detected

Absence of Compton reflection hump above 10 keV

Absorption likely due to neutral or mildly ionized material

Abstract

We present results from a new 100-ks Suzaku observation of the nearby radio galaxy 3C 33, and investigate the nature of absorption, reflection, and jet production in this source. We model the 2-70 keV nuclear continuum with a power law that is absorbed either through one or more layers of pc-scale neutral material, or through a modestly ionized pc-scale obscurer. The expected signatures of reflection from a neutral accretion disk are absent in 3C 33: there is no evidence of a relativistically blurred Fe K$\alpha$ emission line, and no Compton reflection hump above 10 keV. We discuss the implications of this for the nature of jet production in 3C 33.
