PublicationA census of young stellar populations in the warm ULIRG PKS 1345+12
We present a detailed investigation of the young stellar populations (YSP) in the radio-loud ultraluminous infrared galaxy (ULIRG), PKS1345+12 (z = 0.12), based...

PublicationA SINFONI view of circum-nuclear star-forming rings in spiral galaxies
We present near-infrared (H- and K-band) SINFONI integral-field observations of the circumnuclear star formation rings in five nearby spiral galaxies. We made...

PublicationA SLUGGS and Gemini/GMOS combined study of the elliptical galaxy M60: wide-field photometry and kinematics of the globular cluster system
We present new wide-field photometry and spectroscopy of the globular clusters (GCs) around NGC 4649 (M60), the third brightest galaxy in the Virgo cluster...

PublicationA study of correlation between the oscillation amplitude and stellar parameters of delta Scutis in open clusters. Toward selection rules for delta Scuti star oscillations
In the present work, we study correlations between stellar fundamental parameters and the oscillation amplitude for delta Scuti stars. We present this study for...

PublicationA study of the color-magnitude diagrams and luminosity functions of the two LMC clusters NGC 2134 and NGC 2249 with the new radiative opacities
We present Johnson CCD photometry in the B and V passbands for the stellar content of two intermediate age star clusters of the Large Magellanic Cloud (LMC)...

PublicationA Third Massive Star Component in the σ Orionis AB System
We report on the detection of a third massive star component in the σ Orionis AB system, traditionally considered as a binary system. The system has been...

PublicationAge Estimates for Globular Clusters in NGC 1399
We present high signal-to-noise Keck spectra for 10 globular clusters associated with the giant Fornax elliptical galaxy NGC 1399 and compare measured line...

PublicationAges and metallicities of globular clusters in NGC 4472
We have derived ages and metallicities from co-added spectra of 131 globular clusters associated with the giant elliptical galaxy NGC 4472. Based upon a...
