Probing the Low Mass X-ray Binaries/Globular Cluster connection in NGC1399

TL;DR

This study investigates how the structural properties of globular clusters influence the formation of low mass X-ray binaries in NGC1399, revealing factors beyond mass and metallicity.

Contribution

It provides new evidence that GC structural parameters affect LMXB formation, independent of galactocentric distance, using combined HST/ACS and Chandra data.

Findings

LMXB formation likelihood depends on GC structural parameters.

Structural influences are independent of galactocentric distance.

Data combines high-resolution HST and Chandra observations.

Abstract

We present a wide field study of the Globular Clusters/Low Mass X-ray Binaries connection in the cD elliptical NGC1399, combining HST/ACS and Chandra high resolution data. We find evidence that LMXB formation likelihood is influenced by GCs structural parameters, in addition to the well known effects of mass and metallicity, independently from galactocentric distance.
