    2-D Numerical Simulation of the Ambipolar Filamentation of Turbulent Magnetic Fields
    Magnetic fields play an important role in astrophysics and they often dominate the behavior of magnetized media. We simulate the mechanism (Tagger et al., 1995)...

    A Closer View of the Nucleus of NGC 4314
    We present a high-resolution kinematical study of the ionized gas in the circumnuclear region of NGC 4314. Our spectra reveal the presence of a central...

    A comprehensive observational study of the young barred galaxy NGC 3359
    We combine H_α and broad-band optical imaging and H_α velocity mapping over the face of the barred galaxy NGC 3359, obtained within the BARS programme on the...

    A Photometric System for Metallicity Mapping in Galaxies
    A new photometric system suitable for deep, precise and quick metallicity mapping in galaxies is proposed. We find a linear correlation between our metallicity...

    A possible nineteen-minute periodicity in the light curve of OJ 287
    A periodic signal of high nominal significance (99.95%) is found in the light curve of OJ 287 in observations taken with the Prime Focus Camera Unit on the 2.5...

    A Search for Warm Neutral Gas Associated with the Giant HII Region NGC 604
    The characteristics of the halo gas and its interaction with the galactic disk in spiral galaxies are poorly known; this is particularly true for the warm...
