An atlas of Hubble Space Telescope STIS spectra of Seyfert galaxies
Spinelli, Patrícia Figueiro; Storchi-Bergmann, Thaisa; Brandt, Carlos Henrique; Calzetti, Daniela (2006) [Journal article]We present a compilation of spectra of 101 Seyfert galaxies obtained with the Hubble Space Telescope (HST ) Space Telescope Imaging Spectrograph (STIS), covering the UV and/or optical spectral range. Information on all the ... -
Chemical abundance calibrations for the narrow-line region of active galaxies
Storchi-Bergmann, Thaisa; Schmitt, Henrique Roberto; Calzetti, Daniela; Kinney, Anne Louise (1998) [Journal article]We investigate two chemical abundance calibrations for the narrow-line region (NLR) of active galaxies in terms of three easily observable optical emission-line ratios, namely, [O III] λλ4959, 5007/Hβ; [N II] λλ6548, ... -
Dust and recent star formation in the core of ngc 5253
Calzetti, Daniela; Meurer, Gerhardt R.; Bohlin, Ralph C.; Garnett, Donald R.; Kinney, Anne Louise; Leitherer, Claus; Storchi-Bergmann, Thaisa (1997) [Journal article]Ultraviolet and optical narrow and broad band images of NGC 5253 obtained with the Hubble Space Te/escape Wide Field and Planetary Camera 2 are used to derive the properties of the dust distribution and the recent star ... -
Dust extinction of the stellar continua in Starburst galaxies : the ultraviolet and optical extinction law
Calzetti, Daniela; Kinney, Anne Louise; Storchi-Bergmann, Thaisa (1994) [Journal article]We analyze the IUE UV and the optical spectra of 39 starburst and blue compact galaxies in order to study the average properties of dust extinction in extended regions of galaxies. The optical spectra have been obtained ... -
Dust obscuration in starburst galaxies from near-infrared spectroscopy
Calzetti, Daniela; Kinney, Anne Louise; Storchi-Bergmann, Thaisa (1996) [Journal article]We present new observations of the near-infrared hydrogen recombination lines Paβ and Bry in the central starburst regions of 13 galaxies. The near-infrared data are supplemented with data on the optical Balmer line emission ... -
Template ultraviolet to near-infrared spectra of star-forming galaxies and their application to K-corrections
Kinney, Anne Louise; Calzetti, Daniela; Bohlin, Ralph C.; Mcquade, Kerry; Storchi-Bergmann, Thaisa; Schmitt, Henrique Roberto (1996) [Journal article]Template UV-optical spectra of quiescent and starburst galaxies are presented and used to derive K corrections as a function of morphological type and redshift. IUE observations and archival data are used for the UV ... -
The dust content and opacity of actively star-forming galaxies
Calzetti, Daniela; Armus, Lee; Bohlin, Ralph C.; Kinney, Anne Louise; Koornneef, Jan; Storchi-Bergmann, Thaisa (2000) [Journal article]We present far-infrared (FIR) photometry at 150 and 205 μm of eight low-redshift starburst galaxies obtained with the Infrared Space Observatory (ISO) ISOPHOT. Five of the eight galaxies are detected in both wave bands, ... -
The heating of dust in starburst galaxies : the contribution of the nonionizing radiation
Calzetti, Daniela; Bohlin, Ralph C.; Kinney, Anne Louise; Storchi-Bergmann, Thaisa; Heckman, Timothy M. (1995) [Journal article]The IUE UV and optical spectra and the far-infrared (FIR) IRAS flux densities of a sample of starburst and blue compact galaxies are used to investigate the relationship between dust obscuration and dust emission. The ... -
The reddening law outside the local group galaxies : the case of NGC 7552 and NGC 5236
Kinney, Anne Louise; Calzetti, Daniela; Bica, Eduardo Luiz Damiani; Storchi-Bergmann, Thaisa (1994) [Journal article]The dust reddening law from the UV to the near-IR for the extended regions of galaxies is here derived from the spectral distributions of the starburst spiral galaxies NGC 7552 and NGC 5236. The centers of these galaxies ... -
The spectral energy distribution of normal, starburst, and active galaxies
Schmitt, Henrique Roberto; Kinney, Anne Louise; Calzetti, Daniela; Storchi-Bergmann, Thaisa (1997) [Journal article]We present the results of an extensive literature search of multiwavelength data for a sample of 59 galaxies, consisting of 26 Starbursts, 15 Seyfert 2's, 5 LINER's, 6 normal spirals, and 7 normal elliptical galaxies. The ... -
Ultraviolet to near-infrared spectral distributions of star-forming galaxies : metallicity and age effects
Storchi-Bergmann, Thaisa; Calzetti, Daniela; Kinney, Anne Louise (1994) [Journal article]Spectral distributions from the UV to the near-IR of a sample of 44 star-forming galaxies are used to calculate the metallicity (0/H), star-formation rate (SFR) and age of the starbursts. The oxygen abundance covers the ...
