AKARI Infrared Camera Survey of the Large Magellanic Cloud. I. Point-source Catalog
Onaka, Takashi; Tanabé, Toshihiko; Ita, Yoshifusa +10 more
We present a near- to mid-infrared point-source catalog of five photometric bands at 3.2, 7, 11, 15, and 24 µm for a 10 deg2 area of the Large Magellanic Cloud (LMC) obtained with the Infrared Camera on board the AKARI satellite. To cover the survey area the observations were carried out at three separate seasons from 2006 May to …
The Connection between 3.3 µm Polycyclic Aromatic Hydrocarbon Emission and Active Galactic Nucleus Activity
Imanishi, Masatoshi; Kim, Ji Hoon; Woo, Jong-Hak +1 more
We investigate the connection between starburst and active galactic nucleus (AGN) activity by comparing 3.3 µm polycyclic aromatic hydrocarbon (PAH) emission with AGN properties. Utilizing the slitless spectroscopic capability of the AKARI space telescope, we observe a moderate-luminosity Type I AGN at z ~ 0.4 to measure global starburst act…
Wide-field Survey of Emission-line Stars in IC 1396
Ishihara, D.; Ueno, M.; Watanabe, M. +3 more
We have made an extensive survey of emission-line stars in the IC 1396 H II region to investigate the low-mass population of pre-main-sequence (PMS) stars. A total of 639 Hα emission-line stars were detected in an area of 4.2 deg2 and their i' photometry was measured. Their spatial distribution exhibits several aggregates near the eleph…
Detecting Variability in Massive Astronomical Time-series Data. II. Variable Candidates in the Northern Sky Variability Survey
Chang, Seo-Won; Kim, Dae-Won; Byun, Yong-Ik +2 more
We present variability analysis of data from the Northern Sky Variability Survey (NSVS). Using the clustering method, which defines variable candidates as outliers from large clusters, we cluster 16,189,040 light curves having data points at more than 15 epochs as variable and non-variable candidates in 638 NSVS fields. Variable candidates are sel…
A Catalog of Galactic Infrared Carbon Stars
Chen, P. S.; Yang, X. H.
We collected almost all of the Galactic infrared carbon stars (IRCSs) from literature published up to the present to organize a catalog of 974 Galactic IRCSs in this paper. Some of their photometric properties in the near-, mid-, and far-infrared are discussed.
AKARI/AcuA Physical Studies of the Cybele Asteroid Family
Hasegawa, Sunao; Usui, Fumihiko; Ootsubo, Takafumi +4 more
We present a study of 107 Cybele asteroids based on the archival database "Asteroid Catalog Using AKARI (AcuA)" taken by the Infrared Astronomical Satellite. The database provides diameters D > 10 km, geometric albedos, and taxonomic information (75%) of the Cybeles. We find taxonomic diversity (mainly C-, D-, and P-type) in the population of 7…
