Nobeyama CO Atlas of Nearby Spiral Galaxies
The results of a CO(1–0) map** survey of 40 nearby spiral galaxies performed with the Nobeyama 45-m telescope are presented. The maps of CO cover most of the optical disk of the galaxies. We investigated the...

VERA Project
In this paper we review the current status of VERA (VLBI Exploration of Radio Astrometry) project. First, we present an overview of VERA, and then we report on recent results from VERA, particularly the parall...

Radial Velocity Search for Extrasolar Planets in Binary Systems
We have started a search for extrasolar planets in visual binary systems from 2003. We monitor them by precise radial velocity measurements, using High Dispersion Echelle Spectrograph(HIDES) equipped on the Ok...

The Neutrino Burst from Supernovae and Neutrino Oscillations
Core-collapse driven supernovae are the most luminous neutrino source in the universe. If neutrinos have finite masses and convert into each other, the time profile and energy spectrum of the neutrino burst fr...

Stellar Mass of Faint Mid-Infrared Galaxies
Near-infrared emission is a good estimator of stellar masses of galaxies. For galaxies at high redshifts, mid-infrared observations are needed to trace the near-infrared emission at the rest-frame. A deep mid-...

Power Spectrum Analysis of Far-Infrared Sky Brightness in the Lockman Hole
We investigate the characteristics of far-infrared brightness fluctuations at 90 μm and 170 μm in the Lockman Hole which were surveyed with ISO, using power spectrum analysis over the spatial frequency range o...

ISO Deep Far-Infrared Survey in the Lockman Hole
Two 44’ ×44’ fields in the Lockman hole have been surveyed at 95 and 175μm with ISOPHOT. The raw data were reduced by PIA up to AAP products and then the responsivity drift was corrected by the median filter t...

A K-Band Luminosity Function of Hickson Compact Groups of Galaxies
Figure 1. A K-band luminosity function of Hickson Compact Groups of Galaxies. The data were obtained at the University of Hawaii Planetary Patrol 24 inch telescope with a NICMOS3 camera. The K-band luminosity ...

Spin-Down of Neutron Stars and Compositional Transitions in the Cold Crustal Matter
Transitions of nuclear compositions in the crust of a neutron star induced by stellar spin-down are evaluated at zero temperature. We construct a compressible liquid-drop model for the energy of nuclei immerse...

ASCA Observation of Groups of Galaxies
Based on the ASCA observations, the X-ray features like spatial extentions and spectral properties of their component were analyzed for nearby four compact groups of galaxies; HCG62, NGC2300 group, HCG42 and H...

A Large-Scale CO Imaging of the Galactic Center
Molecular gas in the Galactic center region is spatially and kinematically complex, and its physical conditions are distinctively different from those of molecular gas in the Galactic disk (e.g., Morris 1996). Re...

Three-Dimensional Simulation Study of Plasmoid Injection into Magnetized Plasma
Resent observations suggest that, during solar flares, plasmoids are injected into the interplanetary medium (Stewart et al., 1982). It has also been pointed out that solar wind irregularities modeled as plasmoid...

CO Map** of the Inner Few Hundred Parsecs of the Galaxy
We have made high resolution map** observations of 12CO ( J=l−0) and 13CO ( J=l−0) from the central few hundred parsecs of the Galaxy using the NRO 45m telescope (HPBW=16″). The high resolution CO maps reveal m...

Multigroup Simulation of Protoneutron Star Cooling
As well known, the data of the neutrino burst from SN1987A observed by KAMI-OKANDE-II and 1MB show good agreement with the theoretical model of protoneutron star cooling developed by mainly BURROWS and LATTIME...
