Description
VCC 1249 is dwarf irregular galaxy located within the halo of Messier 49 (M49), the brightest galaxy in the Virgo galaxy cluster. The gravitational interaction between the two galaxies leads to accretion of matter, including globular clusters, from VCC 1249 into the intracluster light of the Virgo cluster and the halo of M49. Understanding galactic interactions like these can improve our knowledge of galaxy formation and life cycles of galaxies.
In my contribution, I will present new data from the ESO MUSE integral-field spectrograph that allowed us to measure the kinematics of VCC 1249 and the surrounding material with spectral fitting. The data also allowed for the identification of globular clusters in the vicinity of VCC 1249, where we found two new putative globular clusters. Some of the globular clusters were found to trace the accreted material, while others were bound to VCC 1249.
