We present preliminary results of the surface photometry of a sample of blue compact dwarf galaxies (BCDGs). A total of 28 galaxies have been observed in the BVRI bands. From these data the contour maps and surface brightness distributions in each band have been built. Contour maps and surface profiles of the 22 galaxies already analysed are

The LEGRI Science Operation Center (SOC) is the single contact point between the MINISAT-01 Centro de Operaciones Científicas (COC) located at Villafranca del Castillo (Madrid) and the LEGRI Consortium. Its architecture, operational procedures and associated software has been developed at the Universities of Valencia and Birmingham on the scope to

Two years after launch (04.21.97), LEGRI is operating on Minisat-01 in a LEO orbit. The LEGRI detector plane is formed by two type of gamma-ray solid state detectors: HgI_2 and CdZnTe. Detectors are embedded in a box containing the FEE and DFE electronics. This box provides an effective detector passive shielding. Detector plane is multiplexed by a

LEGRI has been operating successfully on MINISAT-01 since its switch-on the 22nd of May 1997. HouseKeeping (HK) data have been continuously received for nearly two years by LEGRI SOC in Valencia, and subsequently checked on a daily basis and then stored for long term monitoring analysis. LEGRI HouseKeeping data include three critical operating

We present a comparison between the ionized gas and stellar kinematics for a sample of five early-to-intermediate disc galaxies. We measured the major axis V and σ radial profiles for both gas and stars, and the h_3 and h_4 radial profiles of the stars. We also derived from the R-band surface photometry of each galaxy the light contribution of

Images are presented of some of the galaxies in the sample of the BARS `International Time Project' in the near-infrared JHK_s bands, obtained with the Infra-Red Camera at the 1.5 m Carlos Sánchez Telescope, Teide Observatory, between 1996 and 1998. We discuss the scientific importance of imaging galaxies in the near-infrared bands and recent and
