The DEEP Groth Strip Survey. I. The Sample
Weiner, Benjamin J.; Illingworth, Garth D.; Rhodes, Jason +18 more
The Deep Extragalactic Exploratory Probe (DEEP) is a multiphase research program dedicated to the study of the formation and evolution of galaxies and of large-scale structure in the distant universe. This paper describes the first five-year phase, denoted DEEP1. A series of 10 DEEP1 papers will discuss a range of scientific topics (e.g., the stud…
The DEEP Groth Strip Survey. VIII. The Evolution of Luminous Field Bulges at Redshift z ~ 1
Weiner, Benjamin J.; Bouwens, Rychard J.; Gebhardt, Karl +12 more
We present a candidate sample of luminous bulges (including ellipticals) found within the Groth Strip Survey (GSS), with spectroscopic redshifts of 0.73<z<1.04 from the Keck Telescope. This work is distinguished by its use of two-dimensional two-component decomposition photometry from Hubble Space Telescope (HST) images to separate the bulge…
Integral Field Spectroscopy of 23 Spiral Bulges
Marconi, A.; Capetti, A.; Scarlata, C. +7 more
We have obtained integral-field spectroscopy for 23 spiral bulges using INTEGRAL on the William Herschel Telescope and SPIRAL on the Anglo-Australian Telescope. This is the first two-dimensional survey directed solely at the bulges of spiral galaxies. Eleven galaxies of the sample do not have previous measurements of the stellar velocity dispersio…
Comparison of Star Clusters With and Without Wolf-Rayet Stars in Wolf-Rayet Galaxies
Kobulnicky, Henry A.; Dufour, Reginald J.; Buckalew, Brent A.
We compare the properties of young star clusters with and without Wolf-Rayet (W-R) stars in W-R galaxies using optical, near-infrared imagery and optical spectroscopy. Our work identifies the clusters with W-R stars in these galaxies for the first time. With this information, comparisons of clusters with and without W-R stars are now possible, ena…
The Interplanetary Network Supplement to the BATSE Catalogs of Untriggered Cosmic Gamma-Ray Bursts
Frontera, F.; Cline, T.; Hurley, K. +16 more
We present Interplanetary Network (IPN) detection and localization information for 211 gamma-ray bursts (GRBs) observed as untriggered events by the Burst and Transient Source Experiment (BATSE) and published in catalogs by Kommers et al. and Stern et al. IPN confirmations have been obtained by analyzing the data from 11 experiments. For any given…
Catalog of Galaxy Morphology in Four Rich Clusters: Luminosity Evolution of Disk Galaxies at 0.33 < z < 0.83
Saintonge, Amélie; Yee, H. K. C.; Carlberg, R. G. +2 more
Hubble Space Telescope (HST) imaging of four rich, X-ray-luminous, galaxy clusters (0.33<z<0.83) is used to produce quantitative morphological measurements for galaxies in their fields. Catalogs of these measurements are presented for 1642 galaxies brighter than F814W(AB)=23.0. Galaxy luminosity profiles are fitted with three models: exponen…
Interstellar Ice: The Infrared Space Observatory Legacy
Whittet, D. C. B.; Tielens, A. G. G. M.; Boogert, A. C. A. +1 more
We present 2.5-30 µm spectra from the Short-Wavelength Spectrometer of the Infrared Space Observatory for a total of 23 sources. The sources include embedded young stellar objects spanning a wide range of mass and luminosity, together with field stars sampling quiescent dark clouds and the diffuse interstellar medium. Expanding on results of…
GEMS: Galaxy Evolution from Morphologies and SEDs
Bell, Eric F.; Somerville, Rachel S.; Wisotzki, Lutz +13 more
GEMS (Galaxy Evolution from Morphologies and SEDs) is a large-area (800 arcmin2) two-color (F606W and F850LP) imaging survey with the Advanced Camera for Surveys on the Hubble Space Telescope. Centered on the Chandra Deep Field-South, it covers an area of ~28'×28', or about 120 Hubble Deep Field areas, to a depth o…
The 24 Micron Source Counts in Deep Spitzer Space Telescope Surveys
Rigby, J. R.; Le Floc'h, E.; Dole, H. +20 more
Galaxy source counts in the infrared provide strong constraints on the evolution of the bolometric energy output from distant galaxy populations. We present the results from deep 24 µm imaging from Spitzer surveys, which include ~5×104 sources to an 80% completeness of ~=60 µJy. The 24 µm counts rapidly rise at near-Eu…
Photoionization Modeling and the K Lines of Iron
Kallman, T. R.; Krolik, J. H.; Bautista, M. A. +2 more
We calculate the efficiency of iron K line emission and iron K absorption in photoionized models using a new set of atomic data. These data are more comprehensive than those previously applied to the modeling of iron K lines from photoionized gases and allow us to systematically examine the behavior of the properties of line emission and absorptio…
