The gas of the Seyfert 2 galaxy NGC 5252 consists of an ionized bicone of gas and a region of neutral gas which fills the regions outside the ionized bicone. We present new HI maps of the neutral components with a spatial resolution which exceeds previously available maps by a factor of 2. In addition, the ionized component was imaged in the Hα

The Universidad Complutense de Madrid (UCM) Survey is a long-term project aiming at finding and analysing star-forming galaxies detected by their H$alpha$ emission in Schmidt objective-prism plates. The instrumental set-up limits the volume of the Universe surveyed to a redshift $zlesssim0.045$. So far we have discovered several hundred emission

Howardites contain dark, carbonaceous chondrite clasts making up a few percent of these meteoritic breccias. This work utilizes a micro-coring technique to extract 1-20 microgram-sized samples of these clasts from thin sections, and micro-INAA techniques to obtain trace element concentrations. The hope was that the trace element geochemical details

The development of effective iterative methods capable of accurately solving NLTE Stokes transfer problems is of considerable importance for the investigation of solar and stellar magnetic fields. After briefly indicating the iterative approach which is being presently pursued for the exact solution of such problems, the particular regime where
