AKARI Near-infrared Spectroscopy of the Extended Green Object G318.05+0.09: Detection of CO Fundamental Ro-vibrational Emission
Onaka, Takashi; Sakon, Itsuki; Mori, Tamami +1 more
We present the results of near-infrared (2.5-5.4 µm) long-slit spectroscopy of the extended green object (EGO) G318.05+0.09 with AKARI. Two distinct sources are found in the slit. The brighter source has strong red continuum emission with H2O ice, CO2 ice, and CO gas and ice absorption features at 3.0, 4.25 µm, 4.…
Evaluation of standoff distance method to determine the coronal magnetic field using CME-driven shocks
Shanmugaraju, A.; Suresh, K.; Syed Ibrahim, M.
We have analyzed the propagation characteristics of four limb coronal mass ejections (CMEs) with their shocks. These CMEs were observed in 18 frames up to 18 solar radii using LASCO white light images. Gopalswamy and Yashiro (Astrophys. J. 736:L17, 2011) introduced the standoff distance method (SOD) to find the magnetic field in the corona using C…
Suzaku observation of a high-entropy cluster Abell 548W
Makishima, Kazuo; Nakazawa, Kazuhiro; Gu, Liyi +4 more
Abell 548W, one of the galaxy clusters located in the Abell 548 region, has about an order of magnitude lower X-ray luminosity compared to ordinal clusters in view of the well-known intracluster medium (ICM) temperature vs. X-ray luminosity (kT-LX) relation. The cluster hosts a pair of diffuse radio sources to the northwest and north, b…
Corrigendum to "The SESAME/CASSE instrument listening to the MUPUS PEN insertion phase on comet 67P/Churyumov-Gerasimenko" [Acta Astronaut., DOI: 10.1016/j.actaastro.2016.02.018]

Disentangling AGN and Star Formation Activity at High Redshift Using Hubble Space Telescope Grism Spectroscopy
Trump, Jonathan R.; Schneider, Donald P.; Gronwall, Caryl +4 more
Differentiating between active galactic nucleus (AGN) activity and star formation in z ∼ 2 galaxies is difficult because traditional methods, such as line-ratio diagnostics, change with redshift, while multi-wavelength methods (X-ray, radio, IR) are sensitive to only the brightest AGNs. We have developed a new method for spatially resolving emissi…
EU-FP7-iMARS: Analysis of Mars Multi-Resolution Images Using Auto-Coregistration Data Mining and Crowd Source Techniques: Processed Results - a First Look
Willner, Konrad; van Gasselt, Stephan; Tao, Yu +18 more
Understanding planetary atmosphere-surface exchange and extra-terrestrial-surface formation processes within our Solar System is one of the fundamental goals of planetary science research. There has been a revolution in planetary surface observations over the last 15 years, especially in 3D imaging of surface shape. This has led to the ability to …
Narrow-line X-Ray-selected Galaxies in the Chandra-COSMOS Field. I. Optical Spectroscopic Catalog
Civano, F.; Elvis, M.; Watson, M. G. +1 more
The COSMOS survey is a large and deep survey with multiwavelength observations of sources from X-rays to the UV, allowing an extensive study of their properties. The central 0.9 deg2 of the COSMOS field have been observed by Chandra with a sensitivity up to 1.9 × 10-16 erg cm-2 s-1 in the full (0.5-10 ke…
Optical Survey with KMTNet for Dusty Star-Forming Galaxies in the Akari Deep Field South

Morphological Classification of High-redshift Massive Galaxies in the COSMOS/UltraVISTA Field
Kong, Xu; Fang, Guan-wen; Ma, Zhong-yang
Utilizing the multi-band photometric data of the COSMOS (Cosmic Evolution Survey)/UltraVISTA (Ultra-deep Visible and Infrared Survey Telescope for Astronomy) field and the high-resolution HST WFC3 (Hubble Space Telescope Wide Field Camera 3) near-infrared images in the CANDELS (Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey) field,…
Validation of Earth atmosphere models using solar EUV observations from the CORONAS and PROBA2 satellites in occultation mode
Berghmans, David; Slemzin, Vladimir; Kuzin, Sergey +4 more
Aims: Knowledge of properties of the Earth's upper atmosphere is important for predicting the lifetime of low-orbit spacecraft as well as for planning operation of space instruments whose data may be distorted by atmospheric effects. The accuracy of the models commonly used for simulating the structure of the atmosphere is limited by the scarcity …
