Sub-kiloparsec ALMA Imaging of Compact Star-forming Galaxies at z ~ 2.5: Revealing the Formation of Dense Galactic Cores in the Progenitors of Compact Quiescent Galaxies
Rujopakarn, W.; Faber, S. M.; Guo, Y. +10 more
We present spatially resolved Atacama Large Millimeter/submillimeter Array (ALMA) 870 µm dust continuum maps of six massive, compact, dusty star-forming galaxies at z ∼ 2.5. These galaxies are selected for their small rest-frame optical sizes ({r}{{e,F160W}}∼ 1.6 kpc) and high stellar mass densities that suggest that they are dire…
The ALMA Spectroscopic Survey in the Hubble Ultra Deep Field: Continuum Number Counts, Resolved 1.2 mm Extragalactic Background, and Properties of the Faintest Dusty Star-forming Galaxies
Smail, I.; Magnelli, B.; Daddi, E. +31 more
We present an analysis of a deep (1σ = 13 µJy) cosmological 1.2 mm continuum map based on ASPECS, the ALMA Spectroscopic Survey in the Hubble Ultra Deep Field. In the 1 arcmin2 covered by ASPECS we detect nine sources at \gt 3.5σ significance at 1.2 mm. Our ALMA-selected sample has a median redshift of z=1.6+/- 0.4, with only one …
Estimating Distances from Parallaxes. II. Performance of Bayesian Distance Estimators on a Gaia-like Catalogue
Bailer-Jones, Coryn A. L.; Astraatmadja, Tri L.
Estimating a distance by inverting a parallax is only valid in the absence of noise. As most stars in the Gaia catalog will have non-negligible fractional parallax errors, we must treat distance estimation as a constrained inference problem. Here we investigate the performance of various priors for estimating distances, using a simulated Gaia cata…
Estimating Distances from Parallaxes. III. Distances of Two Million Stars in the Gaia DR1 Catalogue
Bailer-Jones, Coryn A. L.; Astraatmadja, Tri L.
We infer distances and their asymmetric uncertainties for two million stars using the parallaxes published in the Gaia DR1 (GDR1) catalogue. We do this with two distance priors: A minimalist, isotropic prior assuming an exponentially decreasing space density with increasing distance, and an anisotropic prior derived from the observability of stars…
L‧CO/LFIR Relations with CO Rotational Ladders of Galaxies Across the Herschel SPIRE Archive
Conley, A.; Glenn, J.; Kamenetzky, J. +2 more
We present a catalog of all CO (J = 4-3 through J = 13-12), [C I], and [N II] lines available from extragalactic spectra from the Herschel SPIRE Fourier Transform Spectrometer (FTS) archive combined with observations of the low-J CO lines from the literature and from the Arizona Radio Observatory. This work examines the relationships between L
ISM Excitation and Metallicity of Star-forming Galaxies at z ≃ 3.3 from Near-IR Spectroscopy
Daddi, E.; Capak, P.; Carollo, C. M. +8 more
We study the relationship between stellar mass, star formation rate (SFR), ionization state, and gas-phase metallicity for a sample of 41 normal star-forming galaxies at 3 ≲ z ≲ 3.7. The gas-phase oxygen abundance, ionization parameter, and electron density of ionized gas are derived from rest-frame optical strong emission lines measured on near-i…
Morphologies of ~190,000 Galaxies at z = 0-10 Revealed with HST Legacy Data. II. Evolution of Clumpy Galaxies
Ouchi, Masami; Harikane, Yuichi; Shibuya, Takatoshi +1 more
We investigate the evolution of clumpy galaxies with Hubble Space Telescope (HST) samples of ∼17,000 photo-z and Lyman break galaxies at z ≃ 0-8. We detect clumpy galaxies with off-center clumps in a self-consistent algorithm that is well tested with previous study results, and we measure the number fraction of clumpy galaxies at the rest-frame UV…
Measurements of Extragalactic Background Light from the Far UV to the Far IR from Deep Ground- and Space-based Galaxy Counts
Cohen, Seth; Driver, Simon P.; Robotham, Aaron S. G. +7 more
We combine wide and deep galaxy number-count data from the Galaxy And Mass Assembly, COSMOS/G10, Hubble Space Telescope (HST) Early Release Science, HST UVUDF, and various near-, mid-, and far-IR data sets from ESO, Spitzer, and Herschel. The combined data range from the far UV (0.15 µm) to far-IR (500 µm), and in all cases the contrib…
The Swift Gamma-Ray Burst Host Galaxy Legacy Survey. I. Sample Selection and Redshift Distribution
Cenko, S. B.; Greiner, J.; Berger, E. +20 more
We introduce the Swift Gamma-Ray Burst Host Galaxy Legacy Survey (“SHOALS”), a multi-observatory high-redshift galaxy survey targeting the largest unbiased sample of long-duration gamma-ray burst (GRB) hosts yet assembled (119 in total). We describe the motivations of the survey and the development of our selection criteria, including an assessmen…
VLA and ALMA Imaging of Intense Galaxy-wide Star Formation in z ∼ 2 Galaxies
Elbaz, D.; Ivison, R. J.; Scott, D. +30 more
We present ≃0.″4 resolution extinction-independent distributions of star formation and dust in 11 star-forming galaxies (SFGs) at z = 1.3-3.0. These galaxies are selected from sensitive blank-field surveys of the 2‧ × 2‧ Hubble Ultra-Deep Field at λ = 5 cm and 1.3 mm using the Karl G. Jansky Very Large Array and Atacama Large Millimeter/submillime…
