Swift X-Ray Observations of Classical Novae. II. The Super Soft Source Sample
Walter, Frederick M.; Drake, Jeremy J.; Woodward, Charles E. +9 more
The Swift gamma-ray burst satellite is an excellent facility for studying novae. Its rapid response time and sensitive X-ray detector provides an unparalleled opportunity to investigate the previously poorly sampled evolution of novae in the X-ray regime. This paper presents Swift observations of 52 Galactic/Magellanic Cloud novae. We included the…
The HETDEX Pilot Survey. I. Survey Design, Performance, and Catalog of Emission-line Galaxies
Finkelstein, Steven L.; Schneider, Donald P.; Blanc, Guillermo A. +23 more
We present a catalog of emission-line galaxies selected solely by their emission-line fluxes using a wide-field integral field spectrograph. This work is partially motivated as a pilot survey for the upcoming Hobby-Eberly Telescope Dark Energy Experiment. We describe the observations, reductions, detections, redshift classifications, line fluxes, …
Very Wide Binaries and Other Comoving Stellar Companions: A Bayesian Analysis of the Hipparcos Catalogue
Olling, Rob P.; Shaya, Ed J.
We develop Bayesian statistical methods for discovering and assigning probabilities to non-random (e.g., physical) stellar companions. These companions are either presently bound or were previously bound. The probabilities depend on similarities in corrected proper motion parallel and perpendicular to the brighter component's motion, parallax, and…
The DEEP3 Galaxy Redshift Survey: Keck/DEIMOS Spectroscopy in the GOODS-N Field
Nandra, Kirpal; Davis, Marc; Juneau, Stéphanie +8 more
We present the results of spectroscopic observations in the GOODS-N field completed using DEIMOS on the Keck II telescope as part of the DEEP3 Galaxy Redshift Survey. Observations of 370 unique targets down to a limiting magnitude of R AB = 24.4 yielded 156 secure redshifts. In addition to redshift information, we provide sky-subtracted…
Chandra ACIS Survey of X-ray Point Sources in 383 Nearby Galaxies. I. The Source Catalog
Liu, Jifeng
The Chandra data archive is a treasure for various studies, and in this paper we exploit this valuable resource to study the X-ray point source populations in nearby galaxies. By 2007 December 14, 383 galaxies within 40 Mpc with isophotal major axis above 1 arcmin had been observed by 626 public ACIS observations, most of which were for the first …
UV-to-FIR Analysis of Spitzer/IRAC Sources in the Extended Groth Strip. I. Multi-wavelength Photometry and Spectral Energy Distributions
Barro, Guillermo; Yamada, T.; Kajisawa, M. +6 more
We present an IRAC 3.6+4.5 µm selected catalog in the Extended Groth Strip (EGS) containing photometry from the ultraviolet to the far-infrared and stellar parameters derived from the analysis of the multi-wavelength data. In this paper, we describe the method used to build coherent spectral energy distributions (SEDs) for all the sources. I…
UV-to-FIR Analysis of Spitzer/IRAC Sources in the Extended Groth Strip. II. Photometric Redshifts, Stellar Masses, and Star Formation Rates
Yamada, T.; Kajisawa, M.; Ashby, M. L. N. +6 more
Based on the ultraviolet to far-infrared photometry already compiled and presented in a companion paper (Paper I), we present a detailed spectral energy distribution (SED) analysis of nearly 80,000 IRAC 3.6 + 4.5 µm selected galaxies in the Extended Groth Strip. We estimate photometric redshifts, stellar masses, and star formation rates (SFR…
What Dominates the Coronal Emission Spectrum During the Cycle of Impulsive Heating and Cooling?
Klimchuk, J. A.; Bradshaw, S. J.
The "smoking gun" of small-scale, impulsive events heating the solar corona is expected to be the presence of hot (>5 MK) plasma. Evidence for this has been scarce, but has gradually begun to accumulate due to recent studies designed to constrain the high-temperature part of the emission measure distribution. However, the detected hot component…
Carina OB Stars: X-ray Signatures of Wind Shocks and Magnetic Fields
Corcoran, Michael F.; Walborn, Nolan R.; Moffat, Anthony F. J. +10 more
The Chandra Carina Complex contains 200 known O- and B-type stars. The Chandra survey detected 68 of the 70 O stars and 61 of 127 known B0-B3 stars. We have assembled a publicly available optical/X-ray database to identify OB stars that depart from the canonical L X/L bol relation or whose average X-ray temperatures exceed 1 …
Structure and Evolution of Debris Disks Around F-type Stars. I. Observations, Database, and Basic Evolutionary Aspects
Apai, D.; Pascucci, I.; Kovács, J. +11 more
Although photometric and spectroscopic surveys with the Spitzer Space Telescope remarkably increased the number of well-studied debris disks around A-type and Sun-like stars, detailed analyses of debris disks around F-type stars remained less frequent. Using the MIPS camera and the Infrared Spectrograph (IRS) spectrograph, we searched for debris d…
