The DEEP Groth Strip Survey. II. Hubble Space Telescope Structural Parameters of Galaxies in the Groth Strip
Weiner, Benjamin J.; Illingworth, Garth D.; Faber, S. M. +7 more
The quantitative morphological classification of distant galaxies is essential to the understanding of the evolution of galaxies over the history of the universe. This paper presents Hubble Space Telescope WFPC2 F606W and F814W photometric structural parameters for 7450 galaxies in the ``Groth Strip.'' These parameters are based on a two-dimension…
Optical and Near-Infrared Imaging of the IRAS 1 Jy Sample of Ultraluminous Infrared Galaxies. II. The Analysis
Veilleux, S.; Sanders, D. B.; Kim, D. -C.
An R and K' atlas of the IRAS 1 Jy sample of 118 ultraluminous infrared galaxies (ULIGs) was presented in a companion paper (our Paper I). The present paper discusses the results from the analysis of these images supplemented with new spectroscopic data obtained at Keck. All but one object in the 1 Jy sample show signs of a strong tidal…
Global Far-Ultraviolet (912-1800 Å) Properties of Star-forming Galaxies
Heckman, Timothy M.; Calzetti, Daniela; Leitherer, Claus +1 more
We present the results of an archival study of the Hopkins Ultraviolet Telescope (HUT) Astro-2 database. Nineteen spectra of star-forming regions and starburst galaxies were retrieved, reprocessed, and analyzed. The spectra cover the wavelength region 912-1800 Å, providing access to the domain of peak luminosity from a young stellar population. We…
Abundances of Deuterium, Nitrogen, and Oxygen in the Local Interstellar Medium: Overview of First Results from the FUSE Mission
Kruk, J. W.; Savage, B. D.; Shull, J. M. +33 more
Observations obtained with the Far Ultraviolet Spectroscopic Explorer (FUSE) have been used to determine the column densities of D I, N I, and O I along seven sight lines that probe the local interstellar medium (LISM) at distances from 37 to 179 pc. Five of the sight lines are within the Local Bubble, and two penetrate the surrounding H I wall. R…
A Hubble Space Telescope Survey of the Mid-Ultraviolet Morphology of Nearby Galaxies
de Jong, Roelof S.; Conselice, Christopher J.; de Grijs, Richard +12 more
We present a systematic imaging survey of 37 nearby galaxies observed with the Hubble Space Telescope (HST) Wide Field and Planetary Camera 2 (WFPC2) in the mid-UV F300W filter, centered at 2930 Å, as well as in the I-band (F814W) filter at 8230 Å. Eleven of these galaxies were also imaged in the F255W filter, centered at 2550 Å. Our sample is car…
CHIANTI-An Atomic Database for Emission Lines. V. Comparison with an Isothermal Spectrum Observed with SUMER
Dere, K. P.; Landi, E.; Feldman, U.
CHIANTI is a database consisting of critically evaluated atomic data and transition probabilities necessary to analyze spectral observations of optically thin plasmas. Previous papers described the content of the database and compared it to a solar active region spectrum between 170 and 450 Å. The aim of the present paper is to compare CHIANTI pre…
The Structure of the Local Interstellar Medium. I. High-Resolution Observations of Fe II, Mg II, and Ca II toward Stars within 100 Parsecs
Redfield, Seth; Linsky, Jeffrey L.
High-resolution absorption measurements (λ/Δλ>~100,000) of the resonance lines of Fe II, Mg II, and Ca II are presented for all available observed targets within 100 pc. The Fe II and Mg II spectra were obtained with the Goddard High Resolution Spectrograph (GHRS) and the Space Telescope Imaging Spectrograph (STIS) instruments aboard the Hubble…
Deuterium Abundance toward G191-B2B: Results from the FUSE Mission
Kruk, J. W.; Sonneborn, G.; Moos, H. W. +19 more
High-resolution spectra of the hot white dwarf G191-B2B, covering the wavelength region 905-1187 Å, were obtained with the Far Ultraviolet Spectroscopic Explorer (FUSE). These data were used in conjunction with existing high-resolution Hubble Space Telescope Space Telescope Imaging Spectrograph (STIS) observations to evaluate the total H I, D I, O…
Classification of 2.4-45.2 Micron Spectra from the Infrared Space Observatory Short Wavelength Spectrometer
Sloan, G. C.; Kraemer, Kathleen E.; Price, Stephan D. +1 more
The Infrared Space Observatory observed over 900 objects with the Short Wavelength Spectrometer in full-grating scan mode (2.4-45.2 µm). We have developed a comprehensive system of spectral classification using these data. Sources are assigned to groups based on the overall shape of the spectral energy distribution (SED). The groups include …
Ultraluminous Infrared Galaxies: Atlas of Near-Infrared Images
Clements, D. L.; Colina, L.; Rowan-Robinson, M. +6 more
A sample of 27 ultraluminous infrared galaxy (ULIRG) systems has been imaged at 1.6 µm using the Hubble Space Telescope (HST) Near Infrared Camera and Multi-Object Spectrometer (NICMOS). These ULIRGs are from a larger sample also imaged with HST in the I band. Images and catalog information for the NICMOS subsample, as well as brief morpholo…
