    • An atlas of H II regions in nearby Seyfert galaxies 

      Evans, I.N.; Koratkar, A.P.; Storchi-Bergmann, Thaisa; Kirkpatrick, H.; Heckman, Timothy M.; Wilson, Andrew S. (1996) [Artigo de periódico]
      Continuum-subtracted Hα images of 17 nearby Seyfert galaxies are presented. The images are calibrated astrometrically usmg the Hubble Space Telescope Guide Star Catalog reference frame. For each galaxy, an inventory of HII ...

    • Gemini/GMOS IFU gas velocity 'tomography' of the narrow line region of nearby active galaxies 

      Barbosa, Fausto Kuhn Berenguer; Storchi-Bergmann, Thaisa; Fernandes Junior, Roberto Cid; Winge, Claudia; Schmitt, Henrique Roberto (2009) [Artigo de periódico]
      We present two-dimensional (2D) mapping of the gas velocity field of the inner few hundred parsecs of six nearby active galaxies, using spectra obtained with the integral field unit of the Gemini Multi-Object Spectrograph ...

    • Infrared array photometry of bulge globular clusters I. Combined ground based JK and HST VI photometry of NGC 6553 

      Guarnieri, M.D.; Ortolani, Sergio; Montegriffo, P.; Renzini, Alvio; Barbuy, Beatriz; Bica, Eduardo Luiz Damiani; Moneti, Andrea (1998) [Artigo de periódico]
      JK infrared photometry for the bulge globular cluster NGC 6553, combined with high resolution visual VI observations are presented and discussed in connection with the bulge metal rich population. The infrared data were ...

    • The physical parameters of the evolving population of faint galaxies 

      Glazebrook, Karl; Abraham, Roberto G.; Santiago, Basilio Xavier; Ellis, Richard S.; Griffiths, Richard E. (1998) [Artigo de periódico]
      The excess number of blue galaxies at faint magnitudes is a subject of much controversy. Recent Hubble Space Telescope results have revealed a plethora of galaxies with peculiar morphologies tentatively identified as the ...

    • Two serendipitous low-mass lmc dusters discovered with hst 

      Santiago, Basilio Xavier; Elson, Rebecca A.W.; Sigurdsson, Steinn; Gilmore, Gerard Fitzgerald (1998) [Artigo de periódico]
      We present V and I photometry of two open clusters in the LMC down to V~26. The clusters were imaged with the Wide Field and Planetary Camera 2 (WFPC2) on board the Hubble Space Telescope (HST), as part of the Medium Deep ...
