Evolution of Interstellar Medium, Star Formation, and Accretion at High Redshift
Aussel, H.; Ivison, R. J.; Ilbert, O. +20 more
ALMA observations of the long wavelength dust continuum are used to estimate the interstellar medium (ISM) masses in a sample of 708 galaxies at z = 0.3 to 4.5 in the COSMOS field. The galaxy sample has known far-infrared luminosities and, hence, star formation rates (SFRs) and stellar masses ({M}* ) from the optical-infrared spectrum f…
A Herschel/PACS Far-infrared Line Emission Survey of Local Luminous Infrared Galaxies
Sanders, D. B.; Surace, J. A.; Inami, H. +20 more
We present an analysis of [O I]63, [O III]88, [N II]122, and [C II]158 far-infrared (FIR) fine-structure line observations obtained with Herschel/PACS, for ∼240 local luminous infrared galaxies (LIRGs) in the Great Observatories All-sky LIRG Survey. We find pronounced declines ("deficits") of line-to-FIR…
The Green Bank Ammonia Survey: First Results of NH3 Mapping of the Gould Belt
Caselli, Paola; Di Francesco, James; Rosolowsky, Erik +23 more
We present an overview of the first data release (DR1) and first-look science from the Green Bank Ammonia Survey (GAS). GAS is a Large Program at the Green Bank Telescope to map all Gould Belt star-forming regions with {A}{{V}}≳ 7 mag visible from the northern hemisphere in emission from NH3 and other key molecular tracers. T…
The Radio Spectral Energy Distribution and Star-formation Rate Calibration in Galaxies
Boquien, M.; De Looze, I.; Murphy, E. J. +17 more
We study the spectral energy distribution (SED) of the radio continuum (RC) emission from the Key Insight in Nearby Galaxies Emitting in Radio (KINGFISHER) sample of nearby galaxies to understand the energetics and origin of this emission. Effelsberg multi-wavelength observations at 1.4, 4.8, 8.4, and 10.5 GHz combined with archive data allow us, …
ISM Properties of a Massive Dusty Star-forming Galaxy Discovered at z ∼ 7
Menten, K. M.; Béthermin, M.; Murphy, E. J. +28 more
We report the discovery and constrain the physical conditions of the interstellar medium of the highest-redshift millimeter-selected dusty star-forming galaxy to date, SPT-S J031132-5823.4 (hereafter SPT0311-58), at z=6.900+/- 0.002. SPT0311-58 was discovered via its 1.4 mm thermal dust continuum emission in the South Pole Telescope (SPT)-SZ surve…
Molecular Outflows in Local ULIRGs: Energetics from Multitransition OH Analysis
Sturm, E.; Veilleux, S.; Farrah, D. +11 more
We report on the energetics of molecular outflows in 14 local ultraluminous infrared galaxies (ULIRGs) that show unambiguous outflow signatures (P Cygni profiles or high-velocity absorption wings) in the far-infrared lines of OH measured with the Herschel/PACS spectrometer. All sample galaxies are gas-rich mergers at various stages of the merging …
Calibrating Star Formation in WISE Using Total Infrared Luminosity
Dale, D. A.; Smith, J. -D. T.; Brown, M. J. I. +3 more
We present accurate resolved WISE photometry of galaxies in the combined SINGS and KINGFISH sample. The luminosities in the W3 12 µm and W4 23 µm bands are calibrated to star formation rates (SFRs) derived using the total infrared luminosity, avoiding UV/optical uncertainties due to dust extinction corrections. The W3 relation has a 1σ…
The Origins of [C II] Emission in Local Star-forming Galaxies
Boquien, M.; Rigopoulou, D.; Armus, L. +17 more
The [C II] 158 µm fine-structure line is the brightest emission line observed in local star-forming galaxies. As a major coolant of the gas-phase interstellar medium, [C II] balances the heating, including that due to far-ultraviolet photons, which heat the gas via the photoelectric effect. However, the origin of [C II] emission remains uncl…
The Complete Infrared View of Active Galactic Nuclei from the 70 Month Swift/BAT Catalog
Ueda, Yoshihiro; Kawamuro, Taiki; Ricci, Claudio +5 more
We systematically investigate the near- to far-infrared (FIR) photometric properties of a nearly complete sample of local active galactic nuclei (AGNs) detected in the Swift/Burst Alert Telescope (BAT) all-sky ultra-hard X-ray (14-195 keV) survey. Out of 606 non-blazar AGNs in the Swift/BAT 70 month catalog at high galactic latitudes of | b| > …
The Herschel Orion Protostar Survey: Luminosity and Envelope Evolution
Manoj, P.; Myers, Philip C.; Fischer, William J. +12 more
The Herschel Orion Protostar Survey obtained well-sampled 1.2-870 µm spectral energy distributions (SEDs) of over 300 protostars in the Orion molecular clouds, home to most of the young stellar objects (YSOs) in the nearest 500 pc. We plot the bolometric luminosities and temperatures for 330 Orion YSOs, 315 of which have bolometric temperatu…
