Age and Metallicity Analysis of the Small Magellanic Cloud from Star Clusters
(2013)
We present metallicities for 15 Small Magellanic Cloud (SMC) star clusters. We add to this information the ages and metallicities of 15 additional star clusters previously studied by Parisi et al. (2009) and Parisi et al. ...
On the redshift of the gamma-ray blazar PKS 0447-439: Optical spectroscopy using Gemini observations with high S/N ratio
(Centro Brasileiro de Pesquisas Físicas (CBPF), 2013)
Environment and properties of obscured and unobscured active galactic nuclei
(Asociación Argentina de Astronomía, 2013)
We analyze the properties of obscured and unobscured active galactic nuclei selected using mid-infrared colors in the redshift range 1 < z < 3. We find that obscured objects are located in a denser local galaxy environment ...
