Hard X-Ray to Radio Multiwavelength SED Analysis of Local U/LIRGs in the GOALS Sample with a Self-consistent AGN Model including a Polar-dust Component
Imanishi, Masatoshi; Tanimoto, Atsushi; Ueda, Yoshihiro +7 more
We conduct hard X-ray to radio multiwavelength spectral energy distribution (SED) decomposition for 57 local luminous and ultraluminous infrared galaxies observed with the Nuclear Spectroscopic Telescope Array and/or Swift/Burst Alert Telescope in the GOALS sample. We modify the latest SED-fitting code X-CIGALE by implementing the infrared (IR) CL…
Extension of HOPS out to 500 pc (eHOPS). I. Identification and Modeling of Protostars in the Aquila Molecular Clouds
Manoj, P.; Narang, Mayank; Gutermuth, Robert A. +14 more
We present a Spitzer/Herschel focused survey of the Aquila molecular clouds (d ~ 436 pc) as part of the eHOPS (extension of the Herschel orion protostar survey, or HOPS, Out to 500 ParSecs) census of nearby protostars. For every source detected in the Herschel/PACS bands, the eHOPS-Aquila catalog contains 1-850 µm SEDs assembled from the Two…
CARMA-NRO Orion Survey: Unbiased Survey of Dense Cores and Core Mass Functions in Orion A
Sanhueza, Patricio; Nakamura, Fumitaka; Shimajiri, Yoshito +16 more
The mass distribution of dense cores is a potential key to understanding the process of star formation. Applying dendrogram analysis to the CARMA-NRO Orion C18O (J = 1-0) data, we identify 2342 dense cores, about 22% of which have virial ratios smaller than 2 and can be classified as gravitationally bound cores. The derived core mass fu…
Panchromatic Photometry of Low-redshift, Massive Galaxies Selected from SDSS Stripe 82
Ho, Luis C.; Zhuang, Ming-Yang; Shangguan, Jinyi +2 more
The broadband spectral energy distribution of a galaxy encodes valuable information on its stellar mass, star formation rate (SFR), dust content, and possible fractional energy contribution from nonstellar sources. We present a comprehensive catalog of panchromatic photometry, covering 17 bands from the far-ultraviolet to 500 µm, for 2685 lo…
Chemical Differentiation around Five Massive Protostars Revealed by ALMA: Carbon-chain Species and Oxygen/Nitrogen-bearing Complex Organic Molecules
Caselli, Paola; Nakamura, Fumitaka; Li, Zhi-Yun +9 more
We present Atacama Large Millimeter/submillimeter Array Band 3 data toward five massive young stellar objects (MYSOs), and investigate relationships between unsaturated carbon-chain species and saturated complex organic molecules (COMs). An HC5N (J = 35-34) line has been detected from three MYSOs, where nitrogen (N)-bearing COMs (CH
CMR Exploration. I. Filament Structure with Synthetic Observations
Klessen, Ralf S.; Arce, Héctor G.; Kong, Shuo +2 more
In this paper, we carry out a pilot parameter exploration for the collision-induced magnetic reconnection (CMR) mechanism that forms filamentary molecular clouds. Following Kong et al., we utilize Athena++ to model CMR in the context of resistive magnetohydrodynamics (MHD), considering the effect from seven physical conditions, including the ohmic…
Investigating the Impact of Metallicity on Star Formation in the Outer Galaxy. I. VLT/KMOS Survey of Young Stellar Objects in Canis Major
Herczeg, Gregory J.; Tabone, Benoît; Fischer, William J. +9 more
The effects of metallicity on the evolution of protoplanetary disks may be studied in the outer Galaxy where the metallicity is lower than in the solar neighborhood. We present the VLT/KMOS integral field spectroscopy in the near-infrared of ~120 candidate young stellar objects (YSOs) in the CMa-ℓ224 star-forming region located at a Galactocentric…
Infrared Galaxies Detected by the Atacama Cosmology Telescope
Kilerci, Ece; Hashimoto, Tetsuya; Goto, Tomotsugu +4 more
We report on 167 infrared (IR) galaxies selected by AKARI and IRAS and detected in the Atacama Cosmology Telescope (ACT) Data Release 5 (DR5) sky maps at the 98, 150, and 220 GHz frequency bands. Of these detections, 134 (80%) of the millimeter counterparts are first-time identifications with ACT. We expand the previous ACT extragalactic source ca…
WISE Green Objects (WGOs): The Massive Star Candidates in the Whole Galactic Plane (∣b∣ < 2°)
Yuan, Jing-Hua; Zhang, Guo-Yin; Zhang, Chang +1 more
Massive young stellar objects (MYSOs) play a crucial role in star formation. Given that MYSOs were previously identified based on the extended structure and the observational data for them is limited, screening the Wide-field Infrared Survey Explorer (WISE) objects showing green features (for the common coding of the 4.6 µm band as the green…
