Spectra of globular clusters in the Sombrero galaxy: evidence for spectroscopic metallicity bimodality
globular clusters: general galaxies: individual: Sombrero (M104: NGC4594) galaxies: star clusters
2011/9/28
We present a large sample of over 200 integrated-light spectra of confirmed globular clusters (GCs) associated with the Sombrero (M104) galaxy taken with the DEIMOS instrument on the Keck telescope. A...

Nuclear inflows of metal-poor interstellar gas triggered by galaxy interactions can account for the systematically lower central oxygen abundances observed in local interacting galaxies. Here, we inve...
