The NuSTAR Serendipitous Survey: The 40-month Catalog and the Properties of the Distant High-energy X-Ray Source Population
Harrison, F. A.; Stern, D.; Zhang, W. W. +35 more
We present the first full catalog and science results for the Nuclear Spectroscopic Telescope Array (NuSTAR) serendipitous survey. The catalog incorporates data taken during the first 40 months of NuSTAR operation, which provide ≈20 Ms of effective exposure time over 331 fields, with an areal coverage of 13 deg2, and 497 sources detecte…
Updated 34-band Photometry for the Sings/KINGFISH Samples of Nearby Galaxies
Helou, G.; Boquien, M.; Roussel, H. +22 more
We present an update to the ultraviolet-to-radio database of global broadband photometry for the 79 nearby galaxies that comprise the union of the KINGFISH (Key Insights on Nearby Galaxies: A Far-Infrared Survey with Herschel) and SINGS (Spitzer Infrared Nearby Galaxies Survey) samples. The 34-band data set presented here includes contributions fr…
Kinematic Structure of Molecular Gas around High-mass YSO, Papillon Nebula, in N159 East in the Large Magellanic Cloud: A New Perspective with ALMA
Lebouteiller, Vianney; Inoue, Tsuyoshi; Tokuda, Kazuki +20 more
We present the ALMA Band 3 and Band 6 results of 12CO(2-1), 13CO(2-1), H30α recombination line, free-free emission around 98 GHz, and the dust thermal emission around 230 GHz toward the N159 East Giant Molecular Cloud (N159E) in the Large Magellanic Cloud (LMC). LMC is the nearest active high-mass star-forming face-on galaxy …
Dust Properties of C II Detected z ∼ 5.5 Galaxies: New HST/WFC3 Near-IR Observations
Kartaltepe, J. S.; Scoville, N. Z.; Riechers, D. A. +7 more
We examine the rest-frame ultraviolet (UV) properties of 10 [C II]λ158 µm-detected galaxies at z ∼ 5.5 in COSMOS using new Hubble Space Telescope/Wide Field Camera 3 near-infrared imaging. Together with pre-existing 158 µm continuum and [C II] line measurements by the Atacama Large Millimeter/submillimeter Array, we study their dust at…
SCUBA-2 Ultra Deep Imaging EAO Survey (STUDIES): Faint-end Counts at 450 µm
Goto, Tomotsugu; Smail, Ian; Bunker, Andrew J. +40 more
The SCUBA-2 Ultra Deep Imaging EAO Survey (STUDIES) is a three-year JCMT Large Program aiming to reach the 450 µm confusion limit in the COSMOS-CANDELS region to study a representative sample of the high-redshift far-infrared galaxy population that gives rise to the bulk of the far-infrared background. We present the first-year data from STU…
The State-of-the-art HST Astro-photometric Analysis of the Core of ω Centauri. III. The Main Sequence's Multiple Populations Galore
Anderson, J.; Milone, A. P.; Marino, A. F. +5 more
We take advantage of the exquisite quality of the Hubble Space Telescope 26-filter astro-photometric catalog of the core of ω Cen presented in the first paper of this series and the empirical differential-reddening correction presented in the second paper in order to distill the main sequence into its constituent populations. To this end, we restr…
Variable H13CO+ Emission in the IM Lup Disk: X-Ray Driven Time-dependent Chemistry?
Cleeves, L. Ilsedore; Bergin, Edwin A.; Öberg, Karin I. +3 more
We report the first detection of a substantial brightening event in an isotopologue of a key molecular ion, HCO+, within a protoplanetary disk of a T Tauri star. The H13CO+ J=3-2 rotational transition was observed three times toward IM Lup between 2014 July and 2015 May with the Atacama Large Millimeter/submillimet…
On a New Theoretical Framework for RR Lyrae Stars. II. Mid-infrared Period-Luminosity-Metallicity Relations
Madore, Barry F.; Freedman, Wendy L.; Beaton, Rachael L. +14 more
We present new theoretical period-luminosity-metallicity (PLZ) relations for RR Lyræ stars (RRLs) at Spitzer and WISE wavelengths. The PLZ relations were derived using nonlinear, time-dependent convective hydrodynamical models for a broad range of metal abundances (Z = 0.0001-0.0198). In deriving the light curves, we tested two sets of atmospheric…
The SOFIA Massive (SOMA) Star Formation Survey. I. Overview and First Results
Tanaka, Kei E. I.; Zhang, Yichen; Tan, Jonathan C. +6 more
We present an overview and first results of the Stratospheric Observatory For Infrared Astronomy Massive (SOMA) Star Formation Survey, which is using the FORCAST instrument to image massive protostars from ∼10 to 40 µm. These wavelengths trace thermal emission from warm dust, which in Core Accretion models mainly emerges from the inner regio…
Galactic-scale Feedback Observed in the 3C 298 Quasar Host Galaxy
Armus, Lee; Larkin, James E.; Wright, Shelley A. +3 more
We present high angular resolution multiwavelength data of the 3C 298 radio-loud quasar host galaxy (z = 1.439) taken using the W.M. Keck Observatory OSIRIS integral field spectrograph (IFS) with adaptive optics, the Atacama Large Millimeter/submillimeter Array (ALMA), the Hubble Space Telescope (HST) WFC3, and the Very Large Array (VLA).
