# Possible correlations between the emission properties of short GRBs and their offsets from the host galaxies

## TL;DR

This study investigates potential links between the emission characteristics of short gamma-ray bursts and their distances from host galaxies, revealing possible correlations with afterglow emissions.

## Contribution

It is the first to analyze correlations between emission properties and offsets for a sample of 18 SGRBs, including those with and without extended emission.

## Key findings

- No significant difference in offset distribution between SGRBs with and without extended emission.
- Possible correlations found between optical/X-ray afterglow emissions and offsets.
- Physical origins of these correlations are discussed.

## Abstract

Short Gamma-Ray Bursts(SGRBs) are widely believed to be from mergers of binary compact objects involving at least one neutron star and hence have a broad range of spatial offsets from their host galaxies. In this work we search for possible correlations between the emission properties of 18 SGRBs and their offsets from the host galaxies. The SGRBs with and without extended emission do not show significant difference between their offset distribution, in agreement with some previous works. There are however possible correlations between the optical and X-ray afterglow emission and the offsets. The underlying physical origins are examined.
