A 2D array of optical fibers generating simultaneous spectral and spatial information has been used to observe the central 13 arcsec of NGC 5728; on this basis, an analysis of the morphology and kinematics of the galaxy's circumstellar environment is conducted. The kinematic center coincides with the peak in radio emission, but is separated by

The B array of the VLA has observed a sample of seven H II galaxies at 325 and 1489 MHz; the radio continuum spectra thus obtained exhibit a wide variety of spectral shapes, but four show a significant flattening toward lower frequencies. A detailed discussion is conducted of this LF flattening, invoking several radio emission and absorption

An uncrossed echelle spectrograph has been constructed in a collaboration between the Queen's University of Belfast and the Instituto de Astrofísica de Canarias for a series of joint investigations requiring very high spectral resolution observations (up to λ/Δλ ˜ 1O5). It is being used to observe stellar and interstellar lines over the wavelength

EL PRESENTE TRABAJO REPRESENTA UN PASO MAS EN LA BUSQUEDA DE ALGORIMOS POTENTES PARA PODER APROVECHAR TODA LA POTENCIA DE LOS TELESCOPIOS ACTUALES, DE GRANDES DIAMETROS, PERO LIMITADA RESOLUCION ESPACIAL, DEBIDO A LA INFLUENCIA ATMOSFERICA. LA OBTENCION DE IMAGENES DE ALTA RESOLUCION ESPACIAL ES UNO DE LOS PUNTOS DE MAYOR INTERES DE LA ASTROFISICA
