The Dusty Galactic Center as Seen by SCUBA-2
Tilanus, R. P. J.; Currie, M. J.; Chrysostomou, A. +9 more
We present new JCMT SCUBA-2 observations of the Galactic Center region from 355° < l< 5° and b< +/- 1° , covering 10 × 2 square degrees along the Galactic Plane to a depth of 43 mJy beam-1 at 850 µm and 360 mJy beam-1 at 450 µm. We describe the mapping strategy and reduction method used. We present 1…
A Comprehensive Catalog of Galactic Eclipsing Binary Stars with Eccentric Orbits Based on Eclipse Timing Diagrams
Ogłoza, W.; Kim, H. -W.; Kim, C. -H. +3 more
A comprehensive catalog of 623 galactic eclipsing binary (EB) systems with eccentric orbits is presented with more than 2830 times of minima determined from the archived photometric data by various sky-survey projects and new photometric measurements. The systems are divided into two groups according to whether the individual system has a GCVS nam…
Planck Cold Clumps in the λ Orionis Complex. II. Environmental Effects on Core Formation
Ristorcelli, I.; Soam, Archana; Choi, Minho +29 more
Based on the 850 µm dust continuum data from SCUBA-2 at James Clerk Maxwell Telescope (JCMT), we compare overall properties of Planck Galactic Cold Clumps (PGCCs) in the λ Orionis cloud to those of PGCCs in the Orion A and B clouds. The Orion A and B clouds are well-known active star-forming regions, while the λ Orionis cloud has a different…
A New Version of the OCARS Catalog of Optical Characteristics of Astrometric Radio Sources
Malkin, Zinovy
A new version of the Optical Characteristics of Astrometric Radio Sources (OCARS) catalog is presented. This compiled catalog includes radio sources observed in different VLBI programs and experiments that result in source position determination, their redshift, and photometry in the visible and near-infrared bands. A cross-identification table be…
The 3CR Chandra Snapshot Survey: Extragalactic Radio Sources with 0.5 < z < 1.0
Forman, W. R.; Wilkes, B. J.; Liuzzo, E. +10 more
This paper presents the analysis of Chandra X-ray snapshot observations of a subsample of the extragalactic sources listed in the revised Third Cambridge radio catalog (3CR), previously lacking X-ray observations and thus observed during Chandra Cycle 15. This data set extends the current Chandra coverage of the 3CR extragalactic catalog up to red…
Empirical Relations for the Accurate Estimation of Stellar Masses and Radii
Chaplin, William J.; Davies, Guy R.; Moya, Andy +1 more
In this work, we have taken advantage of the most recent accurate stellar characterizations carried out using asteroseismology, eclipsing binaries and interferometry to evaluate a comprehensive set of empirical relations for the estimation of stellar masses and radii. We have gathered a total of 934 stars—of which around two-thirds are on the main…
A Galaxy Redshift Survey Near HST/COS AGN Sight Lines
Savage, Blair D.; Shull, J. Michael; Danforth, Charles W. +8 more
To establish the connection between galaxies and UV-detected absorption systems in the local universe, a deep (g ≤ 20) and wide (∼20‧ radius) galaxy redshift survey is presented around 47 sight lines to UV-bright AGNs observed by the Cosmic Origins Spectrograph (COS). Specific COS science team papers have used this survey to connect absorbers to g…
The Massive Star-forming Regions Omnibus X-ray Catalog, Second Installment
Naylor, Tim; Garmire, Gordon P.; Feigelson, Eric D. +4 more
We present the second installment of the Massive Star-forming Regions (MSFRs) Omnibus X-ray Catalog (MOXC2), a compilation of X-ray point sources detected in Chandra/ACIS observations of 16 Galactic MSFRs and surrounding fields. MOXC2 includes 13 ACIS mosaics, three containing a pair of unrelated MSFRs at different distances, with a total catalog …
The NuSTAR Extragalactic Surveys: Source Catalog and the Compton-thick Fraction in the UDS Field
Harrison, F. A.; Stern, D.; Alexander, D. M. +19 more
We present the results and the source catalog of the NuSTAR survey in the UKIDSS Ultra Deep Survey (UDS) field, bridging the gap in depth and area between NuSTAR’s ECDFS and COSMOS surveys. The survey covers a ∼0.6 deg2 area of the field for a total observing time of ∼1.75 Ms, to a half-area depth of ∼155 ks corrected for vignetting at …
The APOGEE-2 Survey of the Orion Star-forming Complex. I. Target Selection and Validation with Early Observations
Da Rio, Nicola; Pan, Kaike; Majewski, Steven R. +26 more
The Orion Star-forming Complex (OSFC) is a central target for the APOGEE-2 Young Cluster Survey. Existing membership catalogs span limited portions of the OSFC, reflecting the difficulty of selecting targets homogeneously across this extended, highly structured region. We have used data from wide-field photometric surveys to produce a less biased …
