The MUSCLES Treasury Survey. I. Motivation and Overview
DOI: 10.3847/0004-637X/820/2/89 Bibcode: 2016ApJ...820...89F

Loyd, R. O. Parke; Kowalski, Adam F.; Hawley, Suzanne L. +19 more

Ground- and space-based planet searches employing radial velocity techniques and transit photometry have detected thousands of planet-hosting stars in the Milky Way. With so many planets discovered, the next step toward identifying potentially habitable planets is atmospheric characterization. While the Sun-Earth system provides a good framework f…

The Evolution of the Galaxy Stellar Mass Function at z = 4-8: A Steepening Low-mass-end Slope with Increasing Redshift
DOI: 10.3847/0004-637X/825/1/5 Bibcode: 2016ApJ...825....5S

Papovich, Casey; Finkelstein, Steven L.; Dickinson, Mark +16 more

We present galaxy stellar mass functions (GSMFs) at z = 4-8 from a rest-frame ultraviolet (UV) selected sample of ∼4500 galaxies, found via photometric redshifts over an area of ∼280 arcmin2 in the Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey (CANDELS)/Great Observatories Origins Deep Survey (GOODS) fields and the Hubb…

ALMA Spectroscopic Survey in the Hubble Ultra Deep Field: The Infrared Excess of UV-Selected z = 2-10 Galaxies as a Function of UV-Continuum Slope and Stellar Mass
DOI: 10.3847/1538-4357/833/1/72 Bibcode: 2016ApJ...833...72B

Carilli, Chris; Labbé, Ivo; Bouwens, Rychard J. +25 more

We make use of deep 1.2 mm continuum observations (12.7 µJy beam-1 rms) of a 1 arcmin2 region in the Hubble Ultra Deep Field to probe dust-enshrouded star formation from 330 Lyman-break galaxies spanning the redshift range z = 2-10 (to ∼2-3 M yr-1 at 1σ over the entire range). Given the depth and…

The MOSDEF Survey: Electron Density and Ionization Parameter at z ~ 2.3
DOI: 10.3847/0004-637X/816/1/23 Bibcode: 2016ApJ...816...23S

Siana, Brian; Shapley, Alice E.; Reddy, Naveen A. +8 more

Using observations from the MOSFIRE Deep Evolution Field survey, we investigate the physical conditions of star-forming regions in z ∼ 2.3 galaxies, specifically the electron density and ionization state. From measurements of the [O II]λλ3726,3729 and [S II]λλ6716,6731 doublets, we find a median electron density of ∼250 cm-3 at z ∼ 2.3,…

The Chandra COSMOS Legacy survey: optical/IR identifications
DOI: 10.3847/0004-637X/817/1/34 Bibcode: 2016ApJ...817...34M

Finoguenov, A.; Jahnke, K.; Silverman, J. D. +27 more

We present the catalog of optical and infrared counterparts of the Chandra COSMOS-Legacy Survey, a 4.6 Ms Chandra program on the 2.2 deg2 of the COSMOS field, combination of 56 new overlapping observations obtained in Cycle 14 with the previous C-COSMOS survey. In this Paper we report the I, K, and 3.6 µm identifications of the 22…

The SFR-M* Relation and Empirical Star-Formation Histories from ZFOURGE* at 0.5 < z < 4
DOI: 10.3847/0004-637X/817/2/118 Bibcode: 2016ApJ...817..118T

Papovich, Casey; Dickinson, Mark; Inami, Hanae +19 more

We explore star formation histories (SFHs) of galaxies based on the evolution of the star formation rate stellar mass relation (SFR-M*). Using data from the FourStar Galaxy Evolution Survey (ZFOURGE) in combination with far-IR imaging from the Spitzer and Herschel observatories we measure the SFR-M* relation at 0.5 < z <…

Space Telescope and Optical Reverberation Mapping Project. III. Optical Continuum Emission and Broadband Time Delays in NGC 5548
DOI: 10.3847/0004-637X/821/1/56 Bibcode: 2016ApJ...821...56F

Im, M.; Geier, S.; Brandt, W. N. +94 more

We present ground-based optical photometric monitoring data for NGC 5548, part of an extended multiwavelength reverberation mapping campaign. The light curves have nearly daily cadence from 2014 January to July in nine filters (BVRI and ugriz). Combined with ultraviolet data from the Hubble Space Telescope and Swift, we confirm significant time de…

Kiloparsec-scale Dust Disks in High-redshift Luminous Submillimeter Galaxies

Smail, I.; Ivison, R. J.; Menten, K. M. +22 more

We present high-resolution (0.″16) 870 µm Atacama Large Millimeter/submillimeter Array (ALMA) imaging of 16 luminous ({L}{IR}∼ 4× {10}12 {L}) submillimeter galaxies (SMGs) from the ALESS survey of the Extended Chandra Deep Field South. This dust imaging traces the dust-obscured star formation in these z∼ 2.…

On Galactic Density Modeling in the Presence of Dust Extinction
DOI: 10.3847/0004-637X/818/2/130 Bibcode: 2016ApJ...818..130B

Bovy, Jo; Rix, Hans-Walter; Finkbeiner, Douglas P. +2 more

Inferences about the spatial density or phase-space structure of stellar populations in the Milky Way require a precise determination of the effective survey volume. The volume observed by surveys such as Gaia or near-infrared spectroscopic surveys, which have good coverage of the Galactic midplane region, is highly complex because of the abundant…

z ≳ 7 Galaxies with Red Spitzer/IRAC [3.6]-[4.5] Colors in the Full CANDELS Data Set: The Brightest-Known Galaxies at z ~ 7-9 and a Probable Spectroscopic Confirmation at z = 7.48
DOI: 10.3847/0004-637X/823/2/143 Bibcode: 2016ApJ...823..143R

Oesch, P. A.; van Dokkum, P.; Bouwens, R. J. +9 more

We identify four unusually bright (H {}160,{AB} < 25.5) galaxies from Hubble Space Telescope (HST) and Spitzer CANDELS data with probable redshifts z ∼ 7-9. These identifications include the brightest-known galaxies to date at z ≳ 7.5. As Y-band observations are not available over the full CANDELS program to perform a standard Lyman-…
