Multiwavelength analysis as a probe of accretion and radiative processes in LINERs

TL;DR

This study investigates the multiwavelength properties of LINERs to understand their accretion mechanisms, comparing their spectral features with luminous AGN and galactic black-hole X-ray binaries.

Contribution

It provides a comparative analysis of LINERs' spectral energy distributions and X-ray characteristics, shedding light on their accretion processes and connection to other black hole systems.

Findings

LINERs have distinct X-ray spectral features compared to luminous AGN.

Their spectral energy distributions suggest different accretion mechanisms.

Potential links between LINERs and black-hole X-ray binaries are discussed.

Abstract

We study the multiwavelength properties of an optically selected sample of Low Ionization Nuclear Emission-line Regions (LINERs), in an attempt to determine the accretion mechanism powering their central engine. We show how their X-ray spectral characteristics, and their spectral energy distribution compare to luminous AGN, and briefly discuss their connection to their less massive counter-parts galactic black-hole X-ray binaries.
