The origin of the blue tilt in extragalactic globular cluster systems.


Abstract (from CDS):

Some early-type galaxies show a correlation between color and integrated magnitude among the brighter metal-poor globular clusters (GCs). This phenomenon, known as the blue tilt, implies a mass-metallicity relationship among these clusters. In this paper, we show that self-enrichment in GCs can explain several aspects of the blue tilt and discuss predictions of this scenario.
