The Herschel Stripe 82 Survey (HerS): Maps and Early Catalog
Doré, O.; Scott, D.; Jogee, S. +36 more
We present the first set of maps and band-merged catalog from the Herschel Stripe 82 Survey (HerS). Observations at 250, 350, and 500 µm were taken with the Spectral and Photometric Imaging Receiver instrument aboard the Herschel Space Observatory. HerS covers 79 deg2 along the SDSS Stripe 82 to an average depth of 13.0, 12.9, and…
Infrared Spectra and Photometry Of Complete Samples of Palomar-Green and Two Micron All Sky Survey Quasars
Balog, Z.; Rieke, G. H.; Shi, Yong +2 more
As a step toward a comprehensive overview of the infrared (IR) diagnostics of the central engines and host galaxies of quasars at low redshift, we present Spitzer Space Telescope spectroscopic (5-40 µm) and photometric (24, 70, and 160 µm) measurements of all Palomar-Green (PG) quasars at z < 0.5 and Two Micron All Sky Survey (2MASS…
Herschel Key Program, "Dust, Ice, and Gas In Time" (DIGIT): The Origin of Molecular and Atomic Emission in Low-mass Protostars in Taurus
Lee, Jeong-Eun; Lee, Jinhee; Green, Joel D. +2 more
Six low-mass embedded sources (L1489, L1551-IRS5, TMR1, TMC1-A, L1527, and TMC1) in Taurus have been observed with Herschel-PACS to cover the full spectrum from 50 to 210 µm as part of the Herschel key program, "Dust, Ice, and Gas In Time." The relatively low intensity of the interstellar radiation field surrounding Taurus minimizes contamin…
Optical-faint, Far-infrared-bright Herschel Sources in the CANDELS Fields: Ultra-luminous Infrared Galaxies at z > 1 and the Effect of Source Blending
Pérez-González, Pablo G.; Grogin, Norman A.; Koekemoer, Anton M. +13 more
The Herschel very wide field surveys have charted hundreds of square degrees in multiple far-IR (FIR) bands. While the Sloan Digital Sky Survey (SDSS) is currently the best resource for optical counterpart identifications over such wide areas, it does not detect a large number of Herschel FIR sources and leaves their nature undetermined. As a test…
Herschel and Spitzer Observations of Slowly Rotating, Nearby Isolated Neutron Stars
Pavlov, G. G.; Wachter, S.; Posselt, B. +1 more
Supernova fallback disks around neutron stars have been suspected to influence the evolution of the diverse neutron star populations. Slowly rotating neutron stars are the most promising places to find such disks. Searching for the cold and warm debris of old fallback disks, we carried out Herschel PACS (70 µm, 160 µm) and Spitzer IRAC…
A Photon-dominated Region Model for the FIR Mid-J CO Ladder with Universal Rotational Temperature in Star Forming Regions
Lee, Jeong-Eun; Bergin, Edwin A.; Lee, Seokho +1 more
A photon-dominated region (PDR) is one of the leading candidate mechanisms for the origin of warm CO gas with near universal ~300 K rotational temperature inferred from the CO emission detected toward embedded protostars by Herschel/PACS. We have developed a PDR model in general coordinates, where we can use the most adequate coordinate system for…
