    A study of the galaxy redshift distribution towards the cosmic microwave background cold spot in the Corona Borealis supercluster
    We present a study of the spatial and redshift distributions of Sloan Digital Sky Survey (SDSS) galaxies towards the position of CrB-H, a very deep and extended...

    A study of the interplay between ionized gas and star clusters in the central region of NGC 5253 with 2D spectroscopy
    Context. Starbursts are one of the main contributors to the chemical enrichment of the interstellar medium. However, mechanisms governing the interaction...

    A study of the regular structure of the galactic magnetic field using WMAP5 polarization data at 22 GHz
    We study the spatial structure of the 3-dimensional large-scale pattern of the Galactic Magnetic Field using the polarization maps obtained by the WMAP...

    A study of the Type II-P supernova 2003gd in M74
    We present photometric and spectroscopic data of the Type II-P supernova (SN II-P) 2003gd, which was discovered in M74 close to the end of its plateau phase. SN...

    A study shows the unexpected effect of black holes beyond their own galaxies
    At the heart of almost every sufficiently massive galaxy there is a black hole whose gravitational field, although very intense, affects only a small region...

    A Subarcsecond Resolution Near-Infrared Study of Seyfert and ``Normal'' Galaxies. II. Morphology
    We present a detailed study of the bar fraction in the CfA sample of Seyfert galaxies and in a carefully selected control sample of nonactive galaxies to...

    A Subarcsecond-Resolution Near-Infrared Study of Seyfert and ``Normal'' Galaxies. I. Imaging Data
    We present new high-resolution near-infrared observations in the J, H, and K bands, obtained to study the properties of Seyfert host galaxies. The data set...
