Spin Parity of Spiral Galaxies VI -- A Search for Dynamical Memory in the Spin Distribution of Galaxies in HSC WIDE Survey Regions
Masanori Iye, Masafumi Yagi
We analyzed the distribution of spin parity in spiral galaxies using the HSC DR2 data. The spiral winding parity of disk galaxies, observed as S-spiral or Z-spiral projected onto t…
Re-recognized universality of Kozai oscillation on three-body dynamics
Masanori Iye, Takashi Ito
In 1962, Yoshihide Kozai reported his findings on the secular dynamics of asteroids moving in orbits with high inclination and eccentricity. In contrast to the classic understandin…
Spin Parity of Spiral Galaxies IV -- Differential Reddening of Globular Cluster Systems of Nearby Spiral Galaxies
Masanori Iye, Masafumi Yagi
The northwest side of the disk of M31 is known to be the near side because of the differential reddening of globular clusters found from their photographic photometry. This paper r…
Spiral Structure and Differential Dust Size Distribution in the LkHa 330 Disk
E. Akiyama, J. Hashimoto, H. B. Liu +58
Dust trapping accelerates the coagulation of dust particles, and thus it represents an initial step toward the formation of planetesimals. We report -band (1.6 um) linear polari…
The Structure of Pre-transitional Protoplanetary Disks. II. Azimuthal Asymmetries, Different Radial Distributions of Large and Small Dust Grains in PDS~70
J. Hashimoto, T. Tsukagoshi, J. M. Brown +54
The formation scenario of a gapped disk, i.e., transitional disk, and its asymmetry is still under debate. Proposed scenarios such as disk-planet interaction, photoevaporation, gra…
Direct Imaging Detection of Methane in the Atmosphere of GJ 504 b
M. Janson, T. Brandt, M. Kuzuhara +54
Most exoplanets detected by direct imaging so far have been characterized by relatively hot (> ~1000 K) and cloudy atmospheres. A surprising feature in some of their atmospheres ha…
Direct Imaging of a Cold Jovian Exoplanet in Orbit around the Sun-like Star GJ 504
M. Kuzuhara, M. Tamura, T. Kudo +54
Several exoplanets have recently been imaged at wide separations of >10 AU from their parent stars. These span a limited range of ages (<50 Myr) and atmospheric properties, with te…
Near-Infrared Multi-Band Photometry of the Substellar Companion GJ 758 B
M. Janson, J. Carson, C. Thalmann +46
GJ 758 B is a cold (~600K) companion to a Sun-like star at 29 AU projected separation, which was recently detected with high-contrast imaging. Here we present photometry of the com…
Panoramic Views of Cluster-Scale Assemblies Explored by Subaru Wide-Field Imaging
Tadayuki Kodama, the PISCES team
We have started PISCES project; a panoramic imaging and spectroscopic survey of distant clusters on Subaru. It exploits the unique wide-field imaging capability of Suprime-Cam, whi…
A photometric and spectroscopic study of dwarf and giant galaxies in the Coma cluster - V. Dependence of the spectroscopic properties on location in the cluster
D. Carter, B. Mobasher, T. J. Bridges +10
We investigate the radial dependence of the spectroscopic properties, in particular the Mg2, <Fe> and H beta spectroscopic indices, in a sample of galaxies spanning a wide range of…
Ages of S0 and elliptical galaxies in the Coma cluster
B. M. Poggianti, T. Bridges, D. Carter +10
The ages of stellar populations in 52 elliptical and S0 galaxies in the Coma cluster are investigated using a new spectroscopic sample. More than 40% of the S0s are found to have e…
A photometric and spectroscopic study of dwarf and giant galaxies in the Coma cluster - II. Spectroscopic observations
B. Mobasher, T. J. Bridges, D. Carter +10
This is the second paper in a series studying the photometric and spectroscopic properties of galaxies of different luminosities in the Coma cluster. The sample selection, spectros…
