TL;DR
This paper reports the discovery and analysis of a faint globular cluster in the dwarf galaxy Andromeda I, contributing to understanding galaxy formation and dark matter in low-mass systems.
Contribution
It provides detailed properties of a newly identified faint globular cluster in Andromeda I, expanding knowledge of globular clusters in dwarf galaxies.
Findings
The globular cluster has an absolute magnitude of approximately -3.4.
It is part of the increasing population of low-luminosity galaxies with single globular clusters.
The study offers insights into the structure and star formation history of dwarf galaxies.
Abstract
Observations of globular clusters in dwarf galaxies can be used to study a variety of topics, including the structure of dark matter halos and the history of vigorous star formation in low-mass galaxies. We report on the properties of the faint globular cluster (M_V ~ -3.4) in the M31 dwarf galaxy Andromeda I. This object adds to the growing population of low-luminosity Local Group galaxies that host single globular clusters.
