Evolutionary history of the elliptical galaxy NGC 1052
We have obtained Keck spectra for 16 globular clusters (GCs) associated with the merger remnant elliptical NGC 1052, as well as a long-slit spectrum of the...

PublicaciónExplaining the Mysterious Age Gap of Globular Clusters in the Large Magellanic CloudThe Large Magellanic Cloud (LMC) has a unique cluster formation history in that nearly all of its globular clusters were formed either ~13 Gyr ago or less than...

PublicaciónExtragalactic globular cluster near-infrared spectroscopy: II. The stellar population synthesis model zero-point problem extends to the near-infraredMany recent studies have pointed out significant discrepancies between observations and models of stellar populations in the near-infrared (NIR). With current...

PublicaciónExtragalactic Globular Clusters: Old Spectroscopic Ages and New Views on Their FormationWe present the results of a meta-analysis of Keck spectra of extragalactic globular clusters (GCs) in a sample of eight galaxies, ranging from dwarf galaxies to...

PublicaciónFormation of Star Clusters in the Large Magellanic Cloud and Small Magellanic Cloud. I. Preliminary Results on Cluster Formation from Colliding Gas CloudsWe demonstrate that single and binary star clusters can be formed during cloud-cloud collisions triggered by the tidal interaction between the Large and Small...
