CO Observations of the Type Ia Supernova Remnant 3C 397 by the Nobeyama 45-m Radio Telescope: Possible Evidence for the Single-Degenerated Explosion
Daisuke Ito, Hidetoshi Sano, Kazuhiro Nakazawa +4
We present a new CO observation toward the Type Ia supernova remnant (SNR) 3C 397 using the Nobeyama 45-m radio telescope at an unprecedent angular resolution of 18''. We new…
Overall variation of the masers around W Hydrae in 28 years
Hiroshi Imai, Akiharu Nakagawa, Hiroshi Takaba
In this paper, we present the distribution of masers associated with the semi-regular variable star W Hydrae (W Hya). We have collected the radio interferometric data of the…
Time Variations of the Radial Velocity of HO Masers in the Semi-regular Variable R Crt
H. Sudou, M. Shiga, T. Omodaka +2
HO maser emission at 22 GHz in the circumstellar envelope is one of the good tracers of detailed physics and kinematics in the mass loss process of asymptotic giant branch star…
No Microwave Flare of Sagittarius A* around the G2 Periastron Passing
Masato Tsuboi, Yoshiharu Asaki, Osamu Kameya +11
In order to explore any change caused by the G2 cloud approaching, we have monitored the flux density of Sgr A* at 22 GHz from Feb. 2013 to Aug. 2014 with a sub-array of Japanese V…
Observations of 6.7 GHz Methanol Masers with EAVN I: VLBI Images of the first Epoch of Observations
Kenta Fujisawa, Koichiro Sugiyama, Kazuhito Motogi +26
Very long baseline interferometry (VLBI) monitoring of the 6.7 GHz methanol maser allows us to measure the internal proper motions of the maser spots and therefore study the gas mo…
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…
