Intercomparison Study of Time and Frequency Transfer between VLBI and Other Techniques (GPS, ETS8(TCE), TW(DPN) and DMTD)
Hiroshi Takiguchi, Moritaka Kimura, Tetsuro Kondo +15
We carried out the intercomparison experiments between VLBI and other techniques to show the capability of VLBI time and frequency transfer by using the current geodetic VLBI techn…
Propagation of Highly Efficient Star Formation in NGC 7000
Hideyuki Toujima, Takumi Nagayama, Toshihiro Omodaka +3
We surveyed the (1,1), (2,2), and (3,3) lines of NH3 and the H2O maser toward the molecular cloud L935 in the extended HII region NGC 7000 with an angular resolution of 1.6' using…
VLBI Detections of Parsec-Scale Nonthermal Jets in Radio-Loud Broad Absorption Line Quasars
Akihiro Doi, Noriyuki Kawaguchi, Yusuke Kono +19
We conducted radio detection observations at 8.4 GHz for 22 radio-loud broad absorption line (BAL) quasars, selected from the Sloan Digital Sky Survey (SDSS) Third Data Release, by…
NH3 in the Galactic Center is formed in Cool Conditions
Takumi Nagayama, Toshihiro Omodaka, Toshihiro Handa +5
It is an open question why the temperature of molecular gas in the Galactic center region is higher than that of dust. To address this problem, we made simultaneous observations in…
The 2006 Radio Outburst of a Microquasar Cyg X-3: Observation and Data
M. Tsuboi, T. Tosaki, N. Kuno +22
We present the results of the multi-frequency observations of radio outburst of the microquasar Cyg X-3 in February and March 2006 with the Nobeyama 45-m telescope, the Nobeyama Mi…
A Complete Survey of the Central Molecular Zone in NH3
Takumi Nagayama, Toshihiro Omodaka, Toshihiro Handa +4
We present a map of the major part of the central molecular zone (CMZ) of simultaneous observations in the NH3 (J,K) = (1,1) and (2,2) lines using the Kagoshima 6-m telescope. The…
