Infrared Spectra and Optical Constants of Nitrile Ices Relevant to Titan's Atmosphere
Moore, Marla H.; Ferrante, Robert F.; Moore, W. James +1 more
Spectra and optical constants of nitrile ices known or suspected to be in Titan's atmosphere are presented from 2.0 to 333.3 µm (~5000-30 cm-1). These results are relevant to the ongoing modeling of Cassini CIRS observations of Titan's winter pole. Ices studied are: HCN, hydrogen cyanide; C2N2, cyanogen; CH
Local Luminous Infrared Galaxies. I. Spatially Resolved Observations with the Spitzer Infrared Spectrograph
Pérez-González, Pablo G.; Colina, Luis; Rieke, George H. +5 more
We present results from the Spitzer Infrared Spectrograph spectral mapping observations of 15 local luminous infrared galaxies (LIRGs). In this paper, we investigate the spatial variations of the mid-IR emission which includes fine structure lines, molecular hydrogen lines, polycyclic aromatic features (PAHs), continuum emission, and the 9.7 &micr…
Looking Into the Hearts of Bok Globules: Millimeter and Submillimeter Continuum Images of Isolated Star-forming Cores
Wolf, S.; Henning, Th.; Ward-Thompson, D. +6 more
We present the results of a comprehensive infrared, submillimeter, and millimeter continuum emission study of isolated low-mass star-forming cores in 32 Bok globules, with the aim to investigate the process of star formation in these regions. The submillimeter and millimeter dust continuum emission maps together with the spectral energy distributi…
The Chandra M101 Megasecond: Diffuse Emission
Kuntz, K. D.; Snowden, S. L.
Because M101 is nearly face-on, it provides an excellent laboratory in which to study the distribution of X-ray-emitting gas in a typical late-type spiral galaxy. We obtained a Chandra observation with a cumulative exposure of roughly 1 Ms to study the diffuse X-ray emission in M101. The bulk of the X-ray emission is correlated with the star forma…
White Dwarf-Red Dwarf Systems Resolved with the Hubble Space Telescope. II. Full Snapshot Survey Results
Hoard, D. W.; Farihi, J.; Wachter, S.
Results are presented for a Hubble Space Telescope Advanced Camera for Surveys high-resolution imaging campaign of 90 white dwarfs with known or suspected low-mass stellar and substellar companions. Of the 72 targets that remain candidate and confirmed white dwarfs with near-infrared excess, 43 are spatially resolved into two or more components, a…
The HST/ACS Coma Cluster Survey. II. Data Description and Source Catalogs
Ferguson, Henry C.; Mobasher, Bahram; Miller, Bryan W. +46 more
The Coma cluster, Abell 1656, was the target of an HST-ACS Treasury program designed for deep imaging in the F475W and F814W passbands. Although our survey was interrupted by the ACS instrument failure in early 2007, the partially completed survey still covers ~50% of the core high-density region in Coma. Observations were performed for 25 fields …
An XMM-Newton Survey of the Soft X-ray Background. I. The O VII and O VIII Lines Between l = 120° and l = 240°
Henley, David B.; Shelton, Robin L.
We present measurements of the soft X-ray background (SXRB) O VII and O VIII intensity between l = 120° and l = 240°, the first results of a survey of the SXRB using archival XMM-Newton observations. We do not restrict ourselves to blank-sky observations, but instead use as many observations as possible, removing bright or extended sources by hand…
Optical Images and Source Catalog of AKARI North Ecliptic Pole Wide Survey Field
Im, Myungshin; Lee, Hyung Mok; Lee, Myung Gyoon +3 more
We present the source catalog and the properties of the B-, R-, and I-band images obtained to support the AKARI North Ecliptic Pole Wide (NEP-Wide) survey. The NEP-Wide is an AKARI infrared imaging survey of the north ecliptic pole covering a 5.8 deg2 area over 2.5-6 µm wavelengths. The optical imaging data were obtained at the Ma…
Southern Cosmology Survey. II. Massive Optically Selected Clusters from 70 Square Degrees of the Sunyaev-Zel'dovich Effect Common Survey Area
Hilton, Matt; Hughes, John P.; Kosowsky, Arthur +8 more
We present a catalog of 105 rich and massive (M>3 × 1014 M sun) optically selected clusters of galaxies extracted from 70 deg2 of public archival griz imaging from the Blanco 4 m telescope acquired over 45 nights between 2005 and 2007. We use the clusters' optically derived properties to estimate photometric red…
Deep GALEX Observations of the Coma Cluster: Source Catalog and Galaxy Counts
Hornschemeier, A. E.; Smith, R.; Arnouts, S. +5 more
We present a source catalog from a deep 26 ks Galaxy Evolution Explorer (GALEX) observation of the Coma cluster in the far-UV (FUV; 1530 Å) and near-UV (NUV; 2310 Å) wavebands. The observed field is centered ~0fdg9 (1.6 Mpc) southwest of the Coma core in a well-studied region of the cluster known as "Coma-3." The entire field is located within the…
