We construct a Galacto-Local Group rotation curve, combining the Galactic rotation curve with a diagram, where galacto-centric radial velocities of outer globular clusters and member galaxies of the Local Group are plotted against their galacto-centric distances. The high-velocity ends of this pseudo rotation curve within a radius R ∼ 150 kpc are well traced by a rotation curve calculated for t...

This paper reviews major achievements in the large helical device (LHD) project and discusses the prospects in the upcoming nearest future. The LHD is the largest magnetic confinement device among diversified helical systems and employs superconducting coils. These significant features have enabled comprehensive studies on steady-state net-current free plasmas with plasma parameters comparable ...

Sequential rounds of error-prone PCR to introduce random mutations and screening of the resultant mutant libraries have been used to enhance the total catalytic activity of subtilisin E significantly in a non-natural environment, aqueous dimethylformamide (DMF). Seven DNA substitutions coding for three new amino acid substitutions were identified in a mutant isolated after two additional genera...

The Cold Dark Matter (CDM) structure formation model predicts that about 5-10 percent of a typical galactic halo mass ∼ 10M⊙is in substructures with a mass . 10M⊙. To directly detect such substructures, we propose to observe dust continuum emission from a strongly lensed QSO-host galaxy using a large submillimeter interferometer array with a high angular resolution ∼ 0.01arcsec such as the plan...

In this study we investigate the relation between stellar mass, dust extinction and star formation rate (SFR) using ∼ 150, 000 star-forming galaxies from the SDSS DR7. We show that the relation between dust extinction and SFR changes with stellar mass. For galaxies at the same stellar mass dust extinction is anti-correlated with the SFR at stellar masses < 10M⊙. There is a sharp transition in t...

We have collected all available spectra and photometric data from SDSS catalogue for bright AGNs complied from the first three months of the Fermi large area telescope all-sky survey. Based on the 106 high-confidence and 11 low-confidence association bright AGN list, the photometry data are collected from SDSS DR7 for 28 sources (12 BL Lacs and 16 FSRQs), two of which are low-confidence associa...

Recent observations have demonstrated a significant growth in the integrated stellar mass of the red sequence since z = 1, dominated by a steadily increasing number of galaxies with stellar masses M∗ < 10M⊙. In this paper, we use the COMBO-17 photometric redshift survey in conjunction with deep Spitzer 24μm data to explore the relationship between star formation and the growth of stellar mass. ...

We study the dynamical stability of an additional, potentially habitable planet in the HD 47186 planetary system. Two planets are currently known in this system: a “hot Neptune” with a period of 4.08 days and a Saturn-mass planet with a period of 3.7 years. Here we consider the possibility that one or more undetected planets exist between the two known planets and possibly within the habitable ...

We have obtained high-dispersion spectra for four massive star clusters in the dwarf irregular galaxies NGC 4214 and NGC 4449, using the HIRES spectrograph on the Keck I telescope. Combining the velocity dispersions of the clusters with structural parameters and photometry from images taken with the Hubble Space Telescope, we estimate mass-to-light ratios and compare these with simple stellar p...
