SILVERRUSH. VIII. Spectroscopic Identifications of Early Large-scale Structures with Protoclusters over 200 Mpc at z ∼ 6-7: Strong Associations of Dusty Star-forming Galaxies
Ono, Yoshiaki; Ouchi, Masami; Goto, Tomotsugu +32 more
We have obtained three-dimensional maps of the universe in ∼200 × 200 × 80 comoving Mpc3 (cMpc3) volumes each at z = 5.7 and 6.6 based on a spectroscopic sample of 179 galaxies that achieves ≳80% completeness down to the Lyα luminosity of {log}({L}Lyα }/[{erg} {{{s}}}-1])=43.0, based on our Keck and Gemi…
The East Asian Observatory SCUBA-2 Survey of the COSMOS Field: Unveiling 1147 Bright Sub-millimeter Sources across 2.6 Square Degrees
Thomson, A. P.; Ivison, R. J.; Smail, Ian +28 more
We present sensitive 850 µm imaging of the Cosmological Evolution Survey (COSMOS) field using 640 hr of new and archival observations taken with SCUBA-2 at the East Asian Observatory’s James Clerk Maxwell Telescope. The SCUBA-2 COSMOS survey (S2COSMOS) achieves a median noise level of σ 850µm = 1.2 mJy beam-1 over…
BAT AGN Spectroscopic Survey. XI. The Covering Factor of Dust and Gas in Swift/BAT Active Galactic Nuclei
Ueda, Yoshihiro; Kawamuro, Taiki; Ricci, Claudio +10 more
We quantify the luminosity contribution of active galactic nuclei (AGNs) to the 12 µm, mid-infrared (MIR; 5-38 µm), and total IR (5-1000 µm) emission in the local AGNs detected in the all-sky 70 month Swift/Burst Alert Telescope (BAT) ultrahard X-ray survey. We decompose the IR spectral energy distributions (SEDs) of 587 objects …
HAWC+/SOFIA Multiwavelength Polarimetric Observations of OMC-1
Morris, Mark R.; Staguhn, Johannes; Ward-Thompson, Derek +36 more
We report new polarimetric and photometric maps of the massive star-forming region OMC-1 using the HAWC+ instrument on the Stratospheric Observatory for Infrared Astronomy. We present continuum polarimetric and photometric measurements of this region at 53, 89, 154, and 214 µm at angular resolutions of 5″, 8″, 14″, and 19″ for the four bands…
High Angular Resolution ALMA Images of Dust and Molecules in the SN 1987A Ejecta
Bouchet, P.; Wheeler, J. C.; Matsuura, Mikako +23 more
We present high angular resolution (∼80 mas) ALMA continuum images of the SN 1987A system, together with CO J = 2 \to 1, J = 6 \to 5, and SiO J = 5 \to 4 to J = 7 \to 6 images, which clearly resolve the ejecta (dust continuum and molecules) and ring (synchrotron continuum) components. Dust in the ejecta is asymmetric and clumpy, and overall the du…
The Polycyclic Aromatic Hydrocarbon Mass Fraction on a 10 pc Scale in the Magellanic Clouds
Gordon, Karl D.; Bot, Caroline; Leroy, Adam K. +8 more
We present maps of the dust properties in the Small and Large Magellanic Clouds (SMC, LMC) from fitting Spitzer and Herschel observations with the Draine & Li dust model. We derive the abundance of the small carbonaceous grain (or polycyclic aromatic hydrocarbon; PAH) component. The global PAH fraction ({q}{{PAH}}, the fraction of t…
Multi-wavelength Properties of Type 1 and Type 2 AGN Host Galaxies in the Chandra-COSMOS Legacy Survey
Lusso, Elisabeta; Marchesi, Stefano; Onodera, Masato +6 more
We investigate the multi-wavelength properties of host galaxies of 3701 X-ray-selected active galactic nuclei (AGNs) out to z ∼ 5 in the Chandra-COSMOS Legacy Survey. Thanks to the extensive multi-wavelength photometry available in the COSMOS field, we derive AGN luminosities, host stellar masses, and star formation rates (SFRs) via a multi-compon…
Confirming Herschel Candidate Protoclusters from ALMA/VLA CO Observations
Pérez-Fournon, I.; Valtchanov, I.; Clements, D. L. +11 more
ALMA 870 µm continuum imaging has uncovered a population of blends of multiple dusty star-forming galaxies (DSFGs) in sources originally detected with the Herschel Space Observatory. However, their pairwise separations are much smaller than what is found by ALMA follow-up of other single-dish surveys or expected from theoretical simulations.…
The Main Sequence at z ∼ 1.3 Contains a Sizable Fraction of Galaxies with Compact Star Formation Sizes: A New Population of Early Post-starbursts?
Daddi, E.; Elbaz, D.; Le Floc'h, E. +20 more
Atacama Large Millimeter/submillimeter Array (ALMA) measurements for 93 Herschel-selected galaxies at 1.1 ≤ z ≤ 1.7 in COSMOS reveal a sizable (>29%) population with compact star formation (SF) sizes, lying on average >×3.6 below the optical stellar mass (M ⋆)-size relation of disks. This sample widely spans the star-forming main …
Optically Faint Massive Balmer Break Galaxies at z > 3 in the CANDELS/GOODS Fields
Barro, Guillermo; Pérez-González, Pablo G.; Eliche-Moral, M. Carmen +7 more
We present a sample of 33 Balmer break galaxies (BBGs) selected as Hubble Space Telescope/F160W dropouts in the deepest CANDELS/GOODS fields (H ≳ 27.3 mag) but relatively bright in Spitzer/IRAC ([3.6], [4.5] < 24.5 mag), implying red colors (median and quartiles: < H-[3.6]> ={3.1}2.83.4 {mag}). Half of these BBGs are…
