A Herschel Space Observatory Spectral Line Survey of Local Luminous Infrared Galaxies from 194 to 671 Microns
Gao, Yu; Díaz-Santos, Tanio; Lu, Nanyao +18 more
We describe a Herschel Space Observatory 194-671 µm spectroscopic survey of a sample of 121 local luminous infrared galaxies and report the fluxes of the CO J to J-1 rotational transitions for 4≤slant J≤slant 13, the [N II] 205 µm line, the [C I] lines at 609 and 370 µm, as well as additional and usually fainter lines. The CO spe…
The Great Observatories All-Sky LIRG Survey: Herschel Image Atlas and Aperture Photometry
Sanders, D. B.; Frayer, D. T.; Kim, D. -C. +24 more
Far-infrared images and photometry are presented for 201 Luminous and Ultraluminous Infrared Galaxies [LIRGs: log ({L}{IR}/{L}⊙ )=11.00{--}11.99, ULIRGs: log ({L}{IR}/{L}⊙ )=12.00{--}12.99], in the Great Observatories All-Sky LIRG Survey (GOALS), based on observations with the Herschel Space Observatory …
The Herschel-ATLAS Data Release 2, Paper I. Submillimeter and Far-infrared Images of the South and North Galactic Poles: The Largest Herschel Survey of the Extragalactic Sky
Smith, Matthew W. L.; Dunne, Loretta; Viaene, Sébastien +11 more
We present the largest submillimeter images that have been made of the extragalactic sky. The Herschel Astrophysical Terahertz Large Area Survey (H-ATLAS) is a survey of 660 deg2 with the PACS and SPIRE cameras in five photometric bands: 100, 160, 250, 350, and 500 µm. In this paper we present the images from our two largest field…
The Herschel Planetary Nebula Survey (HerPlaNS): A Comprehensive Dusty Photoionization Model of NGC6781
Villaver, Eva; Ueta, Toshiya; Szczerba, Ryszard +9 more
We perform a comprehensive analysis of the planetary nebula (PN) NGC 6781 to investigate the physical conditions of each of its ionized, atomic, and molecular gas and dust components and the object’s evolution, based on panchromatic observational data ranging from UV to radio. Empirical nebular elemental abundances, compared with theoretical predi…
Insights from Synthetic Star-forming Regions. I. Reliable Mock Observations from SPH Simulations
Dale, James E.; Robitaille, Thomas P.; Koepferl, Christine M. +1 more
Through synthetic observations of a hydrodynamical simulation of an evolving star-forming region, we assess how the choice of observational techniques affects the measurements of properties that trace star formation. Testing and calibrating observational measurements requires synthetic observations that are as realistic as possible. In this part o…
Measuring Filament Orientation: A New Quantitative, Local Approach
Green, C. -E.; Dawson, J. R.; Cunningham, M. R. +3 more
The relative orientation between filamentary structures in molecular clouds and the ambient magnetic field provides insight into filament formation and stability. To calculate the relative orientation, a measurement of filament orientation is first required. We propose a new method to calculate the orientation of the one-pixel-wide filament skelet…
