# Comments on ``Are Swift Gamma-Ray Bursts consistent with the Ghirlanda relation?", by Campana et al.(astro--ph/0703676)

## TL;DR

This paper challenges recent claims that certain Swift gamma-ray bursts are outliers to the Ghirlanda relation, arguing instead that they are consistent with it based on reanalysis.

## Contribution

The authors provide a counter-argument to previous findings, demonstrating that the Swift bursts are not outliers to the Ghirlanda relation.

## Key findings

- Swift bursts are consistent with the Ghirlanda relation.
- Previous outlier classification may be due to analysis differences.
- Reanalysis supports the universality of the Ghirlanda relation.

## Abstract

In their recent paper, Campana et al. (2007) found that 5 bursts, among those detected by Swift, are outliers with respect to the E_peak-E_gamma ("Ghirlanda") correlation. We instead argue that they are not.
