Gas and Dust in a Submillimeter Galaxy at z = 4.24 from the Herschel Atlas
Valtchanov, I.; Ivison, R. J.; Menten, K. M. +39 more
We report ground-based follow-up observations of the exceptional source, ID 141, one of the brightest sources detected so far in the Herschel Astrophysical Terahertz Large Area Survey cosmological survey. ID 141 was observed using the IRAM 30 m telescope and Plateau de Bure interferometer (PdBI), the Submillimeter Array, and the Atacama Pathfinder…
Constraints on the Assembly and Dynamics of Galaxies. I. Detailed Rest-frame Optical Morphologies on Kiloparsec Scale of z ~ 2 Star-forming Galaxies
Förster Schreiber, N. M.; Genzel, R.; Cresci, G. +5 more
We present deep and high-resolution Hubble Space Telescope NIC2 F160W imaging at 1.6 µm of six z ~ 2 star-forming galaxies with existing near-infrared integral field spectroscopy from SINFONI at the Very Large Telescope. The unique combination of rest-frame optical imaging and nebular emission-line maps provides simultaneous insight into mor…
Mid-Infrared Spectral Diagnostics of Luminous Infrared Galaxies
Sturm, E.; Veilleux, S.; Surace, J. A. +21 more
We present a statistical analysis of the mid-infrared (MIR) spectra of 248 luminous infrared (IR) galaxies (LIRGs) which comprise the Great Observatories All-sky LIRG Survey (GOALS) observed with the Infrared Spectrograph (IRS) on board the Spitzer Space Telescope. The GOALS sample enables a direct measurement of the relative contributions of star…
Propagating Waves Along Spicules
De Pontieu, Bart; Okamoto, Takenori J.
Alfvénic waves are thought to play an important role in coronal heating and acceleration of solar wind. Here we investigate the statistical properties of Alfvénic waves along spicules (jets that protrude into the corona) in a polar coronal hole using high-cadence observations of the Solar Optical Telescope on board Hinode. We developed a technique…
X-Ray Properties of the First Sunyaev-Zel'dovich Effect Selected Galaxy Cluster Sample from the South Pole Telescope
Gladders, M. D.; Ade, P. A. R.; Rest, A. +60 more
We present results of X-ray observations of a sample of 15 clusters selected via their imprint on the cosmic microwave background from the thermal Sunyaev-Zel'dovich (SZ) effect. These clusters are a subset of the first SZ-selected cluster catalog, obtained from observations of 178 deg2 of sky surveyed by the South Pole Telescope (SPT).…
The Relation between Black Hole Mass and Host Spheroid Stellar Mass Out to z ~ 2
Treu, Tommaso; Auger, Matthew W.; Malkan, Matthew A. +2 more
We combine Hubble Space Telescope images from the Great Observatories Origins Deep Survey with archival Very Large Telescope and Keck spectra of a sample of 11 X-ray-selected broad-line active galactic nuclei in the redshift range 1 < z < 2 to study the black-hole-mass-stellar-mass relation out to a look-back time of 10 Gyr. Stellar masses o…
The Brightest of Reionizing Galaxies Survey: Design and Preliminary Results
Shull, J. M.; Treu, T.; Trenti, M. +7 more
We present the first results on the search for very bright (M AB ≈ -21) galaxies at redshift z ~ 8 from the Brightest of Reionizing Galaxies (BoRG) survey. BoRG is a Hubble Space Telescope Wide Field Camera 3 (WFC3) pure-parallel survey that is obtaining images on random lines of sight at high Galactic latitudes in four filters (F606W, …
Three Millisecond Pulsars in Fermi LAT Unassociated Bright Sources
Abdo, A. A.; Camilo, F.; Çelik, Ö. +33 more
We searched for radio pulsars in 25 of the non-variable, unassociated sources in the Fermi LAT Bright Source List with the Green Bank Telescope at 820 MHz. We report the discovery of three radio and γ-ray millisecond pulsars (MSPs) from a high Galactic latitude subset of these sources. All of the pulsars are in binary systems, which would have mad…
Extreme Emission-line Galaxies in CANDELS: Broadband-selected, Starbursting Dwarf Galaxies at z > 1
Wuyts, S.; Jahnke, K.; Dickinson, M. +29 more
We identify an abundant population of extreme emission-line galaxies (EELGs) at redshift z ~ 1.7 in the Cosmic Assembly Near-IR Deep Extragalactic Legacy Survey imaging from Hubble Space Telescope/Wide Field Camera 3 (HST/WFC3). Sixty-nine EELG candidates are selected by the large contribution of exceptionally bright emission lines to their near-i…
z ~ 4 Hα Emitters in the Great Observatories Origins Deep Survey: Tracing the Dominant Mode for Growth of Galaxies
Dickinson, Mark; Yan, Chi-Hung; Chary, Ranga-Ram +4 more
We present evidence for strong Hα emission in galaxies with spectroscopic redshifts in the range of 3.8 < z < 5.0 over the Great Observatories Origins Deep Survey fields. Among 74 galaxies detected in the Spitzer IRAC 3.6 and 4.5 µm bands, more than 70% of the galaxies show clear excess at 3.6 µm compared to the expected flux den…
