The Subaru/XMM-Newton Deep Survey (SXDS) - V. Optically Faint Variable Object Survey
Tomoki Morokuma, Mamoru Doi, Naoki Yasuda +19
We present our survey for optically faint variable objects using multi-epoch (8-10 epochs over 2-4 years) -band imaging data obtained with Subaru Suprime-Cam over 0.918 deg…
The Subaru/XMM-Newton Deep Survey (SXDS) - VI. Properties of Active Galactic Nuclei Selected by Optical Variability
Tomoki Morokuma, Mamoru Doi, Naoki Yasuda +11
We present the properties of active galactic nuclei (AGN) selected by optical variability in the Subaru/XMM-Newton Deep Field (SXDF). Based on the locations of variable components…
The Effect of Poloidal Magnetic Field on Type I Planetary Migration: Significance of Magnetic Resonance
Takayuki Muto, Masahiro N. Machida, Shu-ichiro Inutsuka
We study the effect of poloidal magnetic field on type I planetary migration by linear perturbation analysis in the shearing-sheet approximation and the analytic results are compar…
The Elongations and Supersonic Motions of Molecular Clouds
Jin Koda, Tsuyoshi Sawada, Tetsuo Hasegawa +1
New 13CO data from the BU-FCRAO Milky Way Galactic Ring Survey (GRS) are analyzed to understand the shape and internal motions of molecular clouds. For a sample of more than five h…
On Heating of Cluster Cooling Flows by Sound Waves
Yutaka Fujita, Takeru Ken Suzuki
We investigate heating of the cool core of a galaxy cluster through the dissipation of sound waves excited by the activities of the central active galactic nucleus (AGN). Using a w…
Making the corona and the fast solar wind: a self-consistent simulation for the low-frequency Alfven waves from photosphere to 0.3AU
Takeru K. Suzuki, Shu-ichiro Inutsuka
We show that the coronal heating and the fast solar wind acceleration in the coronal holes are natural consequence of the footpoint fluctuations of the magnetic fields at the photo…
The Reionization History and Early Metal Enrichment inferred from the Gamma-Ray Burst Rate
T. Murakami, D. Yonetoku, M. Umemura +2
Based on the gamma-ray burst (GRB) event rate at redshifts of , which is assessed by the spectral peak energy-to-luminosity relation recently found by Yonetoku et…
Tsunamis in Galaxy Clusters: Heating of Cool Cores by Acoustic Waves
Yutaka Fujita, Takeru Ken Suzuki, Keiichi Wada
Using an analytical model and numerical simulations, we show that acoustic waves generated by turbulent motion in intracluster medium effectively heat the central region of a so-ca…
NMA CO (J=1-0) Observations of the Halpha/Radio Lobe Galaxy NGC 3079: Gas Dynamics in a Weak Bar Potential and Central Massive Core
J. Koda, Y. Sofue, K. Kohno +4
within 24 lines with 80 characters) We present ^12CO (1-0) observations in the central 4.5 kpc (1 arcmin) of the Halpha/Radio lobe galaxy NGC 3079 with the Nobeyama Millimeter Arra…
Detecting z > 10 objects through carbon, nitrogen and oxygen emission lines
Maki Suginohara, Tatsushi Suginohara, David N. Spergel
By redshift of 10, star formation in the first objects should have produced considerable amounts of Carbon, Nitrogen and Oxygen. The submillimeter lines of C, N and O redshift into…
Cross-Correlating Cosmic Microwave Background Radiation Fluctuations with Redshift Surveys: Detecting the Signature of Gravitational Lensing
Maki Suginohara, Tatsushi Suginohara, David N. Spergel
Density inhomogeneities along the line-of-sight distort fluctuations in the cosmic microwave background. Usually, this effect is thought of as a small second-order effect that mild…
