Direct Microlensing-Reverberation Observations of the Intrinsic magnetic Structure of AGN in Different Spectral States: A Tale of Two Quasars

TL;DR

This study uses microlensing-reverberation analysis on two quasars in different spectral states to reveal their inner magnetic structures and accretion disk configurations, enhancing understanding of quasar inner regions.

Contribution

It demonstrates how microlensing-reverberation can directly observe and compare the magnetic and accretion structures of quasars in different spectral states.

Findings

Differences in spectral states relate to inner accretion disk radii positions.

Inner structures vary significantly between radio quiet and radio loud quasars.

Observations support models of magnetic supermassive black holes influencing spectral states.

Abstract

We show how direct microlensing-reverberation analysis performed on two well-known Quasars (Q2237 - The Einstein Cross and Q0957 - The Twin) can be used to observe the inner structure of two quasars which are in significantly different spectral states. These observations allow us to measure the detailed internal structure of quasar Q2237 in a radio quiet high-soft state, and compare it to quasar Q0957 in a radio loud low-hard state. We find that the observed differences in the spectral states of these two quasars can be understood as being due to the location of the inner radii of their accretion disks relative to the co-rotation radii of rotating intrinsically magnetic supermassive compact objects in the centers of these quasars.
