Chromospheric Running Wave from a Solar Cyclone Produced through the Emergence of a Twisted Magnetic Flux Tube
Magara, Tetsuya; Inoue, Satoshi; Lee, Hwanhee +3 more
An innovative solar observing satellite, Hinode, has successfully observed the detailed evolution of an emerging magnetic field, starting from its appearance at the solar surface, to forming a developed bipolar region. The high spatial and temporal resolutions provided by the satellite has enabled us to capture prominent dynamic phenomena caused b…
Erratum: X-Ray Study of the Outer Region of Abell 2142 with Suzaku
Hoshino, Akio; Sato, Kosuke; Ohashi, Takaya +4 more
In the paper [PASJ 63, S1019 (2012)], there was an error in the estimation of gas mass. The correct gas mass at the virial radius is 2.40±0.20 × 1014 M⊙. Thus, the gas mass fraction also changes from 14.4+7.1-4.1% to 21.8+10.7-6.3%. Although this value is still consistent with the w…
Asteroid Catalog Using Akari: AKARI/IRC Mid-Infrared Asteroid Survey
Oyabu, Shinki; Hasegawa, Sunao; Onaka, Takashi +10 more
We present the results of an unbiased asteroid survey in the mid-infrared wavelength region with the Infrared Camera (IRC) on board the Japanese infrared satellite AKARI. About 20% of the point source events recorded in the AKARI All-Sky Survey observations are not used for the IRC Point Source Catalog (IRC-PSC) in its production process because o…
X-Ray Study of the Outer Region of Abell 2142 with Suzaku
Hoshino, Akio; Sato, Kosuke; Ohashi, Takaya +4 more
We observed outer regions of a bright cluster of galaxies, A 2142, with Suzaku. Temperature and brightness structures were measured out to the virial radius (

X-Ray Spectrum of a Peculiar Supernova Remnant, G359.1-0.5
Yamaguchi, Hiroya; Koyama, Katsuji; Tsuru, Takeshi Go +3 more
We present Suzaku results of a supernova remnant (SNR), G 359.1-0.5, in the direction of the Galactic center region. From the SNR, we have found prominent K-shell lines of highly ionized Si and S ions, together with unusual structures at 2.5-3.0 and 3.1-3.6 keV. No canonical SNR plasma model, in either ionization equilibrium or under-ionization, c…
MOIRCS Deep Survey. IX. Deep Near-Infrared Imaging Data and Source Catalog
Ouchi, Masami; Tanaka, Ichi; Yamada, Toru +13 more
We present deep J-, H-, and Ks-band imaging data of the MOIRCS Deep Survey (MODS), which was carried out with the Multi-Object Infrared Camera and Spectrograph (MOIRCS) mounted on the Subaru Telescope in the GOODS-North region. The data reach 5σ total limiting magnitudes for point sources of J = 23.9, H = 22.8, and Ks = 22.8 …
Discovery of a Cyclotron Resonance Feature in the X-Ray Spectrum of GX 304-1 with RXTE and Suzaku during Outbursts Detected by MAXI in 2010
Yamaoka, Kazutaka; Makishima, Kazuo; Mihara, Tatehiro +5 more
We report on the discovery of a cyclotron resonance scattering feature (CRSF) in the X-ray spectrum of GX 304
Suzaku Studies of Wide-Band Spectral Variability of the Bright Type I Seyfert Galaxy Markarian 509
Makishima, Kazuo; Nakazawa, Kazuhiro; Yamada, Shin'ya +3 more
The Type I Seyfert galaxy Markarian 509 was observed with Suzaku in 2010 November, for a gross time span of 2.2 days. The timing and spectral properties of the 0.5-45 keV X-rays, detected with the XIS and HXD, consistently revealed the presence of a soft spectral component that remained constant while the total X-ray intensity varied by
Statistical Study on the Nature of Solar-Flux Emergence
Shibata, Kazunari; Ichimoto, Kiyoshi; Kitai, Reizaburo +1 more
We studied 101 flux emergence events ranging from small ephemeral regions to large emerging flux regions that were observed with the Hinode Solar Optical Telescope filtergram. We investigated how the total magnetic flux of the emergence event controls the nature of emergence. To determine the modes of emergences, horizontal velocity fields of the …
