# The Blazar Spectral Sequence and GLAST

## TL;DR

This paper discusses the blazar spectral sequence and how the upcoming GLAST mission will enhance understanding of blazar gamma-ray properties and the relationship between accretion and jet power.

## Contribution

It provides an overview of the blazar spectral sequence and predicts how GLAST's improved sensitivity will advance the field.

## Key findings

- Enhanced ability to determine average gamma-ray properties of blazar classes
- Deeper insights into the ratio of accretion to jet power in systems
- Preparation for GLAST's impact on blazar studies

## Abstract

The present status and understanding of the "spectral sequence" of blazars is discussed in the perspective of the upcoming GLAST launch. The vast improvement in sensitivity will allow to i) determine more objectively the "average" gamma-ray properties of classes objects ii) probe more deeply the ratio between accretion power and jet power in different systems.
