We present preliminary results of long-slit spectroscopic observations of the extended emission line region (hereafter, EELR) in NGC 4388. We detect broad emission lines in the line complexes Hα+[NII] and [SII] which can be modelled by the superposition of several narrow components. Multicomponent line profiles appear at positions very close to the

The Spanish participation as an Associate Member in the Millimeter Array (MMA) project - led by the U.S. National Radio Astronomy Observatory (NRAO) - has been recently proposed to the Spanish Science and Technology Bureau (OCYT). This request to the Spanish Government is based on two key factors: (1) The high scientific interest and support of the

During the last years, inversion techniques have become one of the most powerful tools to obtain, from spectropolarimetric data, the stratification of physical quantities (temperature, pressure, velocity fields, magnetic field, etc.) describing different structures in the solar atmosphere. The SIR code (Stokes Inversion based on Response functions)
