Photospheric Flow Field Related to the Evolution of the Sun's Polar …

We investigated the role of photospheric plasma motions in the formation and evolution of polar magnetic patches using time-sequence observations wit…

The evidence of radio polarization induced by the radiative grain a…

The mechanisms causing millimeter-wave polarization in protoplanetary disks are under debate. To disentangle the polarization mechanisms, we observe …

Probing the shape and internal structure of dark matter halos with th…

Weak lensing three-point statistics are powerful probes of the structure of dark matter halos. We propose to use the correlation of the positions of …

The interstellar medium in [OIII]-selected star-forming galaxies at …

We present new results from near-infrared spectroscopy with Keck/MOSFIRE of [OIII]-selected galaxies at $z\sim3.2$. With our $H$ and $K$-band spectra…

The imprint of $f(R)$ gravity on weak gravitational lensing II : In…

We investigate the information content of various cosmic shear statistics on the theory of gravity. Focusing on the Hu-Sawicki-type $f(R)$ model, we …

We have conducted a search for remnant clouds associated with the formation of TW Hya association in both CO emission, and Na absorption. We find that CO emission is detected towards three peaks of IR brightness, clouds A, B and C. Cloud A is relati…

Search for Remnant Clouds Associated with the TW Hya Association

We report on a search for the parental molecular clouds of the TW Hya association (TWA), using CO emission and Na I absorption lines. TWA is the near…

Properties of star-forming galaxies in a cluster and its surrounding …

We conduct a narrow-band imaging survey of [OII] emitters over a 32'x23' area in and around the XMMXCS J2215.9-1738 cluster at z=1.46 with Subaru/Sup…

Rotation and surface abundance peculiarities in A-type stars

In an attempt of clarifying the connection between the photospheric abundance anomalies and the stellar rotation as well as of exploring the nature o…

Properties of Type II Plateau Supernova SNLS-04D2dc: Multicolor Light…

Shock breakout is the brightest radiative phenomenon in a Type II supernova (SN). Although it was predicted to be bright, the direct observation is d…

Covariance in the Thermal SZ-Weak Lensing Mass Scaling Relation of …

The thermal Sunyaev-Zel'dovich (tSZ) effect signal is widely recognized as a robust mass proxy of galaxy clusters with small intrinsic scatter. Howev…

High-Resolution Spectroscopy of Extremely Metal-Poor Stars from SDS…

Chemical compositions are determined based on high-resolution spectroscopy for 137 candidate extremely metal-poor (EMP) stars selected from the Sloan…

Photospheric Velocity Structures during the Emergence of Small Active…

We study the plasma flows in the solar photosphere during the emergence of two small active regions, NOAA 9021 and 10768. Using SOHO/MDI data, we fin…

Detection of a filament connected to CL0016 with weak gravitational …

We report on the weak lensing detection of a filament between two galaxy clusters at $z=0.55$, CL0015.9+1609 and RX J0018.3+1618. We conduct weak len…

Formation of HI Clouds in Shock-compressed Interstellar Medium: Physi…

Recent observations of neutral Galactic interstellar medium showed that filamentary structures of HI clouds are aligned with the interstellar magneti…

Pseudo Evolution of Galaxy-Cluster Masses and Its Impact on Mass Dens…

A mass of galaxy cluster is commonly defined by a spherical over-density (SO) mass with respect to a reference density, whereas the time evolution of…
