  • A counterrotating core in the merger remnant candidate NGC 3656 (ARP 155)
    A study is presented of the internal velocity structure of NGC 3656, a galaxy with several morphological signatures of being in an advanced merger stage. Rotation curves obtained for two slit-position angles show that the inner 1 kpc rotates around an axis roughly perpendicular to the rotation axis in the main body of the galaxy. There are

  • A deep observation of the ultraluminous X-ray source IC 342 X-1
    Our recent detection of compact radio emission at the position of the ultraluminous X-ray source (ULX) IC 342 X-1 suggests the presence of an outflow in this object. This new finding combined with the fact that this source is mostly seen with a hard X-ray spectrum allows us to identify the source as in the `hard' state similar to that seen from

  • A determination of the space density and birth rate of hydrogen-line (DA) white dwarfs in the Galactic plane, based on the UVEX survey
    We present a determination of the average space density and birth rate of hydrogen-line (DA) white dwarfs within a radius of 1 kpc around the Sun, based on an observational sample of 360 candidate white dwarfs with g 19.5 and (g - r) 0.4, selected from the UV-Excess (UVEX) survey of the northern Galactic plane, in combination with a theoretical

  • A double stellar generation in the globular cluster NGC 6656 (M 22). Two stellar groups with different iron and s-process element abundances
    We present a chemical abundance analysis based on high resolution UVES spectra of seventeen bright giant stars in the Globular Cluster (GC) M 22. We obtained an average iron abundance of [Fe/H] = -1.76±0.02 (internal errors only) and an α enhancement of 0.36±0.04 (internal errors only). Na and O, and Al and O follow the well known anticorrelations
