Stellar Masses and Star Formation Rates for 1M Galaxies from SDSS+WISE
van der Wel, Arjen; Rix, Hans-Walter; da Cunha, Elisabete +1 more
We combine Sloan Digitital Sky Survey (SDSS) and WISE photometry for the full SDSS spectroscopic galaxy sample, creating spectral energy distributions (SEDs) that cover λ = 0.4-22 µm for an unprecedentedly large and comprehensive sample of 858,365 present-epoch galaxies. Using MAGPHYS, we then simultaneously and consistently model both the a…
The FMOS-COSMOS Survey of Star-forming Galaxies at z~1.6. III. Survey Design, Performance, and Sample Characteristics
Daddi, E.; Rodighiero, G.; Ilbert, O. +28 more
We present a spectroscopic survey of galaxies in the COSMOS field using the Fiber Multi-object Spectrograph (FMOS), a near-infrared instrument on the Subaru Telescope. Our survey is specifically designed to detect the Hα emission line that falls within the H-band (1.6-1.8 µm) spectroscopic window from star-forming galaxies with 1.4 < z &l…
Herschel Survey of the Palomar-Green QSOs at Low Redshift
Ho, Luis C.; Scoville, Nicholas Z.; Petric, Andreea O. +1 more
We investigate the global cold dust properties of 85 nearby (z≤slant 0.5) QSOs, chosen from the Palomar-Green sample of optically luminous quasars. We determine their infrared spectral energy distributions and estimate their rest-frame luminosities by combining Herschel data from 70 to 500 µm with near-infrared and mid-infrared measurements …
A Herschel Study of 24 µµm-Selected AGNs and Their Host Galaxies
Smith, G. P.; Egami, E.; Rieke, G. H. +3 more
We present a sample of 290 24 µm-selected active galactic nuclei (AGNs) mostly at z ∼ 0.3-2.5, within 5.2 {{deg}}2 distributed as 25\prime × 25\prime fields around each of 30 galaxy clusters in the Local Cluster Substructure Survey. The sample is nearly complete to 1 mJy at 24 µm, and has a rich multiwavelength set of ancill…
Chemical Abundances and Dust in the Halo Planetary Nebula K648 in M15: Its Origin and Evolution Based on an Analysis of Multiwavelength Data
Otsuka, Masaaki; Hyung, Siek; Tajitsu, Akito
We report on an investigation of the extremely metal-poor and C-rich planetary nebula (PN) K648 in M15 using the UV to far-infrared data obtained using Subaru, the Hubble Space Telescope, the Far Ultraviolet Spectroscopic Explorer, Spitzer, and Herschel. We determined the nebular abundances of 10 elements. The enhancement of F ([F/H] = +0.96) is c…
A Deep Near-infrared Survey toward the Aquila Molecular Cloud. I. Molecular Hydrogen Outflows
Fang, Min; Wang, Hongchi; Wang, Min +4 more
We have performed an unbiased, deep near-infrared survey toward the Aquila molecular cloud with a sky coverage of ∼1 deg2. We identified 45 molecular hydrogen emission-line objects (MHOs), of which only 11 were previously known. Using the Spitzer archival data, we also identified 802 young stellar objects (YSOs) in this region. Based on…
The Warm CO Gas along the UV-heated Outflow Cavity Walls: A Possible Interpretation for the Herschel/PACS CO Spectra of Embedded YSOs
Lee, Jeong-Eun; Bergin, Edwin A.; Lee, Seokho
A fraction of the mid-J (J = 14-13 to J = 24-23) CO emission detected by the Herschel/Photodetector Array Camera and Spectrometer observations of embedded young stellar objects (YSOs) has been attributed to the UV-heated outflow cavity walls. We have applied our newly developed self-consistent models of photon-dominated-region (PDR) and non-local-…
“Dust, Ice, and Gas In Time” (DIGIT) Herschel Observations of GSS30-IRS1 in Ophiuchus
Lee, Jeong-Eun; Green, Joel D.; Je, Hyerin +2 more
As a part of the “Dust, Ice, and Gas In Time” (DIGIT) key program on Herschel, we observed GSS30-IRS1, a Class I protostar located in Ophiuchus (d = 120 pc), with Herschel/Photodetector Array Camera and Spectrometer. More than 70 lines were detected within a wavelength range from 50 to 200 µ m, including CO, H2O, OH, and two atomi…
