# Can GLAST detect gamma-rays from the extended radio features of radio galaxies?

## TL;DR

This paper explores the potential for the Fermi LAT to detect gamma-ray emissions from the extended radio features of radio galaxies, especially focusing on the nearby giant radio galaxy Fornax A.

## Contribution

It investigates the feasibility of detecting gamma-rays from extended radio structures, expanding the scope beyond core emissions in radio galaxies.

## Key findings

- Fornax A is a promising candidate for gamma-ray detection.
- Extended radio features may produce detectable gamma-ray signals.
- Detection prospects depend on the sensitivity of the LAT instrument.

## Abstract

A few FRI radio galaxies were detected at GeV gamma-rays with CGRO EGRET, with peroperties suggesting that the gamma-ray flux originates from the core. Here we discuss the possibility that the extended radio features of radio galaxies could be detected with the LAT, focusing on the particularly promising case of the nearby giant radio galaxy Fornax A.
