Maps of the Magellanic Clouds from Combined South Pole Telescope and PLANCK Data
Bleem, L. E.; Stark, A. A.; George, E. M. +39 more
We present maps of the Large and Small Magellanic Clouds from combined South Pole Telescope (SPT) and Planck data. The Planck satellite observes in nine bands, while the SPT data used in this work were taken with the three-band SPT-SZ camera, The SPT-SZ bands correspond closely to three of the nine Planck bands, namely those centered at 1.4, 2.1, …
Infrared and Ultraviolet Spectra of Methane Diluted in Solid Nitrogen and Irradiated with Electrons during Deposition at Various Temperatures
Chin, Chih-Hao; Chen, Sian-Cong; Liu, Meng-Chen +2 more
We recorded the infrared and ultraviolet absorption spectra of CH4:N2 matrix samples that underwent electron bombardment during deposition in the temperature range of 10-44 K. In contrast to a previous experiment on the IR spectroscopy of electron-bombarded icy samples, methyl and azide radicals became the main products upon …
A Search for Very Low-luminosity Objects in Gould Belt Clouds
Kim, Gwanjeong; Kim, Mi-Ryang; Lee, Chang Won +3 more
We present the results of a search for Very Low-Luminosity Objects (VeLLOs) in the Gould Belt (GB) clouds using infrared and sub-millimeter (sub-mm) data from 1.25 to 850 µm and our {{{N}}}2{{{H}}}+ (J = 1-0) observations. We modified the criteria by Dunham et al. to select the VeLLOs in the GB clouds, finding 95 VeLLO …
The Spitzer-IRAC/MIPS Extragalactic Survey (SIMES) in the South Ecliptic Pole Field
Rodighiero, G.; Papovich, C.; Salvato, M. +25 more
We present the Spitzer-IRAC/MIPS Extragalactic survey (SIMES) in the South Ecliptic Pole field. The large area covered (7.7 deg2), together with one of the lowest Galactic cirrus emissions in the entire sky and a very extensive coverage by Spitzer, Herschel, Akari, and GALEX, make the SIMES field ideal for extragalactic studies. The elo…
A Multi-wavelength 3D Model of BD+30°3639
Freeman, M. J.; Kastner, Joel H.
We present a 3D multi-wavelength reconstruction of BD+30°3639, one of the best-studied planetary nebulae in the solar neighborhood. BD+30°3639, which hosts a [WR]-type central star, has been imaged at wavelength regimes that span the electromagnetic spectrum, from radio to X-rays. We have used the astrophysical modeling software SHAPE to construct…
FK Comae Berenices, King of Spin: The COCOA-PUFS Project
Granzer, T.; Ayres, Thomas R.; Korhonen, H. +8 more
COCOA-PUFS is an energy-diverse, time-domain study of the ultra-fast spinning, heavily spotted, yellow giant FK Comae Berenices (FK Com: HD117555; G4 III). This single star is thought to be a recent binary merger, and is exceptionally active by measure of its intense ultraviolet (UV) and X-ray emissions, and proclivity to flare. COCOA-PUFS was car…
Neon and [C II] 158 µm Emission Line Profiles in Dusty Starbursts and Active Galactic Nuclei
Lebouteiller, Vianney; Samsonyan, Anahit; Weedman, Daniel +2 more
A sample of 379 extragalactic sources is presented that has mid-infrared, high-resolution spectroscopy from the Spitzer Infrared Spectrograph (IRS) and also spectroscopy of the [C II] 158 µm line from the Herschel Photodetector Array Camera and Spectrometer (PACS). The emission line profiles of [Ne II] 12.81 µm, [Ne III] 15.55 µm…
The Young Stellar Population of Lynds 1340. An Infrared View
Apai, D.; Balog, Z.; Kun, M. +4 more
We present results of an infrared study of the molecular cloud Lynds 1340, forming three groups of low- and intermediate-mass stars. Our goals are to identify and characterize the young stellar population of the cloud, study the relationships between the properties of the cloud and the emergent stellar groups, and integrate L1340 into the picture …
Near-Infrared Polarization Source Catalog of the Northeastern Regions of the Large Magellanic Cloud
Tamura, Motohide; Jeong, Woong-Seob; Pak, Soojong +2 more
We present a near-infrared band-merged photometric and polarimetric catalog for the 39‧ × 69‧ fields in the northeastern part of the Large Magellanic Cloud (LMC), which were observed using SIRPOL, an imaging polarimeter of the InfraRed Survey Facility. This catalog lists 1858 sources brighter than 14 mag in the H band with a polarization signal-to…
The Swift AGN and Cluster Survey. II. Cluster Confirmation with SDSS Data
Bregman, Joel N.; Kochanek, Christopher S.; Dai, Xinyu +1 more
We study 203 (of 442) Swift AGN and Cluster Survey extended X-ray sources located in the SDSS DR8 footprint to search for galaxy over-densities in three-dimensional space using SDSS galaxy photometric redshifts and positions near the Swift cluster candidates. We find 104 Swift clusters with a >3σ galaxy over-density. The remaining targets are p…
