TL;DR
This study investigates the presence and properties of Low Mass X-ray Binaries in intra-cluster globular clusters within the Fornax galaxy cluster to understand their origins and environmental influences.
Contribution
It provides the first analysis of LMXB in intra-cluster GCs in the Fornax cluster, extending beyond galaxy centers to explore formation channels and environmental effects.
Findings
Detection of LMXB in intra-cluster GCs
Correlation between LMXB properties and GC environment
Evidence supporting multiple formation channels
Abstract
The formation of Low mass X-ray binaries (LMXB) is favored within dense stellar systems such as Globular Clusters (GCs). The connection between LMXB and Globular Clusters has been extensively studied in the literature, but these studies have always been restricted to the innermost regions of galaxies. We present a study of LMXB in GCs within the central 1.5 deg^2 of the Fornax cluster with the aim of confirming the existence of a population of LMXB in intra-cluster GCs and understand if their properties are related to the host GCs, to the environment or/and to different formation channels.
