An Approach Detecting the Event Horizon of SgrA* (2004)
Imaging the vicinity of black hole is one of the ultimate goals of VLBI astronomy. The closest massive black hole, SgrA*, located at Galactic center is the leading candidate for such observations....

SiO maser survey of AGB stars in the North Galactic Cap (2001)
Ita, Y, Deguchi, S, Fujii, T, Kameya, O, Miyoshi, M, Nakada, Y, ...
A SiO maser survey in the J=1-0, v=1 and 2 transitions has been made for IRAS sources in the North Galactic Cap b > 30o) with the Nobeyama 45 m radio telescope. The sources were selected on the basis...
A 4% Geometric Distance to the Galaxy NGC4258 from Orbital Motions in a Nuclear Gas Disk (1999)
Herrnstein, J. R., Moran, J. M., Greenhill, L. J., Diamond, P. J., Inoue, M., Nakai, N., ...
The water maser in the mildly active nucleus in the nearby galaxy NGC4258 traces a thin, nearly edge-on, subparsec-scale Keplerian disk. Using the technique of very long baseline interferometry, we...
Measurement of geometrical dimensions using scanning electron microscopy (1999)
Komatsu, F., Tsubusaki, K., Miyoshi, M.
In this paper, in-process measurement method of geometrical dimensions of fine patterns using the principle of stereoscopy and digital image processing techniques is presented. We have applied this...
VLBA Continuum Observations of NGC 4258: Constraints on an Advection-Dominated Accretion Flow (1998)
