Optical and CO Radio Observations of Poor Cluster Zwicky 1615.8+3505
A. Tomita, H. Maehara, T. T. Takeuchi +4
The cluster Zwicky 1615.8+3505 is considered to be a dynamically young poor cluster. To investigate the morphology and star-formation activity of galaxies under the environment of…
Study of variable stars in the MOA data base: long-period red variables in the Large Magellanic Cloud
S. Noda, M. Takeuti, F. Abe +31
One hundred and forty six long-period red variable stars in the Large Magellanic Cloud (LMC) from the three year MOA project database were analysed. A careful periodic analysis was…
J-Net Galactic Plane Survey of VLBI Radio Sources for VLBI Exploration of Radio Astrometry (VERA)
M. Honma
In order to search for new VLBI sources in the Galactic plane that can be used as phase reference sources in differential VLBI, we have conducted 22 GHz observations of radio sourc…
Distance and Proper Motion Measurement of the Red Supergiant, S Persei, with VLBI H2O Maser Astrometry
Y. Asaki, S. Deguchi, H. Imai +3
We have conducted VLBA phase-referencing monitoring of H2O masers around the red supergiant, S Persei, for six years. We have fitted maser motions to a simple expanding-shell model…
Nuclear spins, magnetic moments and quadrupole moments of Cu isotopes from N = 28 to N = 46: probes for core polarization effects
P. Vingerhoets, K. T. Flanagan, M. Avgoulea +21
Measurements of the ground-state nuclear spins, magnetic and quadrupole moments of the copper isotopes from 61Cu up to 75Cu are reported. The experiments were performed at the ISOL…
A wide and collimated radio jet in 3C 84 on the scale of a few hundred gravitational radii
G. Giovannini, T. Savolainen, M. Orienti +22
Understanding the launching, acceleration, and collimation of jets powered by active galactic nuclei remains an outstanding problem in relativistic astrophysics. This is partly bec…
