Interplanetary Network Localizations of Konus Short Gamma-Ray Bursts
Frontera, F.; Orlandini, M.; Cline, T. +71 more
Between the launch of the Global Geospace Science Wind spacecraft in 1994 November and the end of 2010, the Konus-Wind experiment detected 296 short-duration gamma-ray bursts (including 23 bursts which can be classified as short bursts with extended emission). During this period, the Interplanetary Network (IPN) consisted of up to 11 spacecraft, a…
Multiband Diagnostics of Unidentified 1FGL Sources with Suzaku and Swift X-Ray Observations
Kataoka, J.; Maeda, K.; Nakamori, T. +3 more
We have analyzed all the archival X-ray data of 134 unidentified (unID) gamma-ray sources listed in the first Fermi/LAT (1FGL) catalog and subsequently followed up by the Swift/XRT. We constructed the spectral energy distributions (SEDs) from radio to gamma-rays for each X-ray source detected, and tried to pick up unique objects that display anoma…
Bright 22 µm Excess Candidates from the Wise All-sky Catalog and the Hipparcos Main Catalog
Yang, Ming; Wu, Hong; Li, Shuo +5 more
In this paper, we present a catalog that includes 141 bright candidates (<=10.27 mag, V band) showing an excess of infrared (IR) at 22 µm. Of these 141 candidates, 38 stars are known IR-excess stars or disks, 23 stars are double or multiple stars, and 4 are Be stars while the remaining more than 70 stars are identified as 22 µm exce…
A New Hα Emission-line Survey in the Orion Nebula Cluster
Pál, A.; Kun, M.; Szegedi-Elek, E. +3 more
We present results from an Hα emission line survey in a 1 deg2 area centered on the Orion Nebula Cluster, obtained with the Wide Field Grism Spectrograph 2 on the 2.2 m telescope of the University of Hawaii. We identified 587 stars with Hα emission, 99 of which, located mainly in the outer regions of the observed area, have not appeared…
Deep Chandra Monitoring Observations of NGC 4649. I. Catalog of Source Properties
Zezas, A.; Luo, B.; Gallagher, J. S. +6 more
We present the X-ray source catalog for the Chandra monitoring observations of the elliptical galaxy, NGC 4649. The galaxy has been observed with Chandra ACIS-S3 in six separate pointings, reaching a total exposure of 299 ks. There are 501 X-ray sources detected in the 0.3-8.0 keV band in the merged observation or in one of the six individual obse…
L1448-MM Observations by the Herschel Key Program, "Dust, Ice, and Gas In Time" (DIGIT)
Choi, Minho; Lee, Jeong-Eun; Lee, Jinhee +7 more
We present Herschel/Photodetector Array Camera and Spectrometer (PACS) observations of L1448-MM, a Class 0 protostar with a prominent outflow. Numerous emission lines are detected at 55 <λ < 210 µm including CO, OH, H2O, and [O I]. We investigate the spatial distribution of each transition to find that lines from low energy …
The Cluster Lensing and Supernova Survey with Hubble: An Overview
Donahue, Megan; Broadhurst, Tom; Moustakas, John +42 more
The Cluster Lensing And Supernova survey with Hubble (CLASH) is a 524-orbit Multi-Cycle Treasury Program to use the gravitational lensing properties of 25 galaxy clusters to accurately constrain their mass distributions. The survey, described in detail in this paper, will definitively establish the degree of concentration of dark matter in the clu…
3D-HST: A Wide-field Grism Spectroscopic Survey with the Hubble Space Telescope
Schmidt, Kasper B.; van Dokkum, Pieter G.; Franx, Marijn +27 more
We present 3D-HST, a near-infrared spectroscopic Treasury program with the Hubble Space Telescope for studying the physical processes that shape galaxies in the distant universe. 3D-HST provides rest-frame optical spectra for a sample of ~7000 galaxies at 1 < z < 3.5, the epoch when ~60% of all star formation took place, the number density o…
The Hawaii Infrared Parallax Program. I. Ultracool Binaries and the L/T Transition
Dupuy, Trent J.; Liu, Michael C.
We present the first results from our high-precision infrared (IR) astrometry program at the Canada-France-Hawaii Telescope. We measure parallaxes for 83 ultracool dwarfs (spectral types M6-T9) in 49 systems, with a median uncertainty of 1.1 mas (2.3%) and as good as 0.7 mas (0.8%). We provide the first parallaxes for 48 objects in 29 systems, and…
Structural Parameters of Galaxies in CANDELS
Kartaltepe, J. S.; Barden, M.; Ferguson, H. C. +19 more
We present global structural parameter measurements of 109,533 unique, H F160W-selected objects from the CANDELS multi-cycle treasury program. Sérsic model fits for these objects are produced with GALFIT in all available near-infrared filters (H F160W, J F125W and, for a subset, Y F105W). The parameters …
