Water Maser Disk and a Supermassive Black Hole at the Nucleus of the Active Galaxy NGC 7738
Rinka Ito, Yusuke Miyamoto, Naomasa Nakai +2
We present the results of very long baseline interferometry (VLBI) observations of water vapor masers in the nucleus of the LINER galaxy NGC 7738. The red- and blue-shifted and new…
Trigonometric parallax and proper motion of Sagittarius A* measured by VERA using the new broad-band back-end system OCTAVE-DAS
Tomoaki Oyama, Takumi Nagayama, Aya Yamauchi +12
We successfully measured the trigonometric parallax of Sagittarius A* (Sgr A*) to be micro-arcseconds (as) using the VLBI Exploration of Radio Astrometry (VERA) with…
Probing the Heart of Active Narrow-line Seyfert 1 Galaxies with VERA Wideband Polarimetry
Mieko Takamura, Kazuhiro Hada, Mareki Honma +9
We explored the parsec-scale nuclear regions of a sample of radio-loud narrow-line Seyfert 1 galaxies (NLSy1s) using the VLBI Exploration of Radio Astronomy (VERA) wideband (at a r…
Demonstration of Ultrawideband Polarimetry Using VLBI Exploration of Radio Astrometry (VERA)
Yoshiaki Hagiwara, Kazuhiro Hada, Mieko Takamura +3
We report on recent technical developments in the front- and back-ends for the four 20 m radio telescopes of the Japanese Very-Long-Baseline Interferometry (VLBI) project, VLBI Exp…
High-sensitivity VLBI Observations of the Water Masers in the Seyfert Galaxy NGC 1068
Yuna Morishima, Hiroshi Sudou, Aya Yamauchi +2
We present observational results of water vapor maser emission with our high-sensitivity 22 GHz VLBI imaging of the Seyfert galaxy NGC 1068. In this galaxy, there are the following…
The First VERA Astrometry Catalog
VERA collaboration, Tomoya Hirota, Takumi Nagayama +59
We present the first astrometry catalog from the Japanese VLBI (very long baseline interferometer) project VERA (VLBI Exploration of Radio Astrometry). We have compiled all the ast…
