The globular cluster system of nearby spirals through multi-band imaging surveys: the case of M81

Abstract

El análisis de los sistemas de cúmulos globulares (SCG) asociados a galaxias espirales cercanas es útil para revelar su historia evolutiva, pero resulta desafiante debido a su gran extensión angular. En la presente contribución nos valemos del gran campo de visión del relevamiento Javalambre Photometric Local Universe Survey (J-PLUS) para encarar el estudio del SCG de la galaxia espiral M81. Estimamos su extensión y población total, y analizamos su distribución de color.

Although the analysis of globular cluster systems (GCSs) in nearby spirals provides relevant information about their evolutionary history, it is challenging because of their angular extension. In this work we take advantage of the large field-of-view of the Javalambre Photometric Local Universe Survey (J-PLUS) to perform a wide-field study of the GCS of the spiral M81. Its extension and population are estimated, and its colour distribution is analysed.
