We present new observations of the field surrounding the Seyfert galaxy NGC 7603, where four galaxies with different redshifts - NGC 7603 (z=0.029), NGC 7603B (z=0.057) and two fainter emission line galaxies (z=0.245 and z=0.394) - are apparently connected by a narrow filament, leading to a possible case of anomalous redshift. The observations

We present the final band-merged European Large-Area ISO Survey (ELAIS) Catalogue at 6.7, 15, 90 and 175 μm, and the associated data at U, g', r', i', Z, J, H, K and 20 cm. The origin of the survey, infrared and radio observations, data-reduction and optical identifications are briefly reviewed, and a summary of the area covered and the

We present new and accurate near-infrared J- and Ks-band data of the Large Magellanic Cloud cluster Reticulum. Data were collected with SOFI at the New Technology Telescope and covered an area of approximately 5'×5' around the center of the cluster. Current data allowed us to derive accurate mean K-band magnitudes for 21 fundamental (RRab) and 9

The distance to the black hole binary GX 339-4 remains a topic of debate. We examine high-resolution optical spectra of the Na D lines resolving the velocity structure along the line of sight. We find this to be complex, with at least nine components, mostly blueshifted, spanning a velocity range of nearly 200 km s-1. The presence of components

We explore possible correlations between the light profile shapes of early-type galaxies, as parameterized by the Sérsic index n, and relevant stellar population parameters, which were obtained from spectra of extremely high signal-to-noise and stellar population models that provide an age indicator that is virtually free of the effects of
