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…
Spitzer MIPS 24 and 70 µm Imaging Near the South Ecliptic Pole: Maps and Source Catalogs
Devlin, Mark J.; Scott, Douglas; Chapin, Edward L. +8 more
We have imaged an 11.5 deg2 region of sky toward the South Ecliptic Pole (R.A. =04h43m, decl. =-53°40', J2000) at 24 and 70 µm with MIPS, the Multiband Imaging Photometer for Spitzer. This region is coincident with a field mapped at longer wavelengths by AKARI and BLAST. We discuss our data reduction and sour…
SpectraFactory.net: A Database of Molecular Model Spectra
Cami, J.; van Malderen, R.; Markwick, A. J.
We present a homogeneous database of synthetic molecular absorption and emission spectra from the optical to mm wavelengths for a large range of temperatures and column densities relevant for various astrophysical purposes, but in particular for the analysis, identification, and first-order analysis of molecular bands in spectroscopic observations…
Absolute Radiometric Calibration of the EUNIS-06 170-205 Å Channel and Calibration Update for Coronal Diagnostic Spectrometer/Normal-Incidence Spectrometer
Brosius, Jeffrey W.; Thomas, Roger J.; Davila, Joseph M. +2 more
The Extreme-Ultraviolet Normal-Incidence Spectrograph sounding-rocket payload was flown on 2006 April 12 (EUNIS-06), carrying two independent imaging spectrographs covering wavebands of 300-370 Å in first order and 170-205 Å in second order, respectively. The absolute radiometric response of the EUNIS-06 long-wavelength (LW) channel was directly m…
