    A slow lopsided bar in the interacting dwarf galaxy IC 3167
    We present surface photometry and stellar kinematics of IC 3167, a dwarf galaxy hosting a lopsided weak bar and infalling into the Virgo cluster. We measured...

    A 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...

    A spectral diagnostic for density-bounded HII regions
    The existence of density-bounded HII regions in spiral galaxies is supported by means of a spectral indicator based on the intensity of the [OI]λ6300 forbidden...

    A Spectral Diagnostic for Density-Bounded HII Regions
    Our spectral diagnostic based on the intensity of the [OI]λ6300Å line indicates that many observed HII regions are indeed density-bounded. The estimated...

    A spectrophotometric study of the Seyfert 1 galaxy NGC 4253
    CCD spectroscopic observations from [NeV] lambda3425A to [SIII] lambda9532A of the nucleus and circumnuclear region of the Seyfert 1 NGC 4253 are presented. The...

    A Spectroscopic Follow-up Program of Very Massive Galaxies at 3 < z < 4: Confirmation of Spectroscopic Redshifts, and a High Fraction of Powerful AGNs
    We present the analysis and results of a spectroscopic follow-up program of a mass-selected sample of six galaxies at 3 z 4 using data from Keck-NIRPSEC and VLT...

    A spectroscopic survey of Abell 1703: is it a rare relaxed cluster hosting a radio halo or a usual merging system?
    We present the study of the internal dynamics of the intriguing galaxy cluster Abell 1703, a system hosting a probable giant radio halo whose dynamical status...

    A spectroscopic view of stellar populations in bulges of low surface brightness galaxies .
    We present the radial profiles of the age, metallicity and alpha /Fe enhancement of the stellar populations in the bulge-dominated region for a sample of eight...
