The 105-Month Swift-BAT All-sky Hard X-Ray Survey
Cenko, S. Bradley; Schawinski, Kevin; Koss, Michael +10 more
We present a catalog of hard X-ray sources detected in the first 105 months of observations with the Burst Alert Telescope (BAT) coded-mask imager on board the Swift observatory. The 105-month Swift-BAT survey is a uniform hard X-ray all-sky survey with a sensitivity of 8.40× {10}-12 {erg} {{{s}}}-1 {cm}}-2 over 90…
The VLA Nascent Disk and Multiplicity Survey of Perseus Protostars (VANDAM). IV. Free-Free Emission from Protostars: Links to Infrared Properties, Outflow Tracers, and Protostellar Disk Masses
Dunham, Michael M.; Kratter, Kaitlin M.; Li, Zhi-Yun +11 more
Emission from protostars at centimeter radio wavelengths has been shown to trace the free-free emission arising from ionizing shocks as a result of jets and outflows driven by protostars. Therefore, measuring properties of protostars at radio frequencies can provide valuable insights into the nature of their outflows and jets. We present a C-band …
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 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 …
The 7-year MAXI/GSC X-Ray Source Catalog in the High Galactic Latitude Sky (3MAXI)
Sakamoto, T.; Mihara, T.; Sugizaki, M. +28 more
We present the third MAXI/GSC catalog in the high Galactic latitude sky (| b| > 10^\circ ) based on the 7-year data from 2009 August 13 to 2016 July 31, complementary to that in the low Galactic latitude sky (| b| < 10^\circ ) (Hori et al. 2018). We compile 682 sources detected at significances of s D,4-10 keV ≥ 6.5 in the 4-10 ke…
The 7-year MAXI/GSC Source Catalog of the Low-Galactic-latitude Sky (3MAXI)
Sakamoto, T.; Mihara, T.; Sugizaki, M. +28 more
We present the first MAXI/GSC X-ray source catalog in the low-Galactic-latitude sky | b| < 10^\circ outside the Galactic center region (| b| < 5^\circ , l < 30°, and l > 330°) based on 7-year data from 2009 August 13 to 2016 July 31. To overcome source confusion in crowded regions, we have accurately calibrated the position-dependent s…
XMM-Newton Survey of Local O VII Absorption Lines in the Spectra of Galactic X-Ray Sources
Fang, Taotao; Luo, Yang; Ma, Renyi
The detection of highly ionized metal absorption lines in the X-ray spectra of the Galactic X-ray binaries (XRBs) implies the distribution of hot gas along the sightline toward the background sources. However, the origin of this hot gas is still unclear: it can arise in the hot interstellar medium (ISM), or is intrinsic to the XRBs. In this paper,…
The Gemini/HST Galaxy Cluster Project: Redshift 0.2-1.0 Cluster Sample, X-Ray Data, and Optical Photometry Catalog
Jørgensen, Inger; Chiboucas, Kristin; Nielsen, Louise D. +2 more
The Gemini/HST Galaxy Cluster Project (GCP) covers 14 z = 0.2-1.0 clusters with X-ray luminosity of {L}500≥slant {10}44 {erg} {{{s}}}-1 in the 0.1-2.4 keV band. In this paper, we provide homogeneously calibrated X-ray luminosities, masses, and radii, and we present the complete catalog of the ground-based photometr…
