Unusual shock-excited OH maser emission in a young Planetary Nebula
Hai-Hua Qiao, Andrew J. Walsh, Jose F. Gomez +9
We report on OH maser emission toward G336.644-0.695 (IRAS 16333-4807), which is a H2O maser-emitting Planetary Nebula (PN). We have detected 1612, 1667 and 1720 MHz OH masers at t…
Three-Dimensional Distribution of the ISM in the Milky Way Galaxy: III. The Total Neutral Gas Disk
Hiroyuki Nakanishi, Yoshiaki Sofue
We present newly obtained three-dimensional gaseous maps of the Milky Way Galaxy; HI, H and total-gas (HI plus H) maps, which were derived from the HI and CO(--…
A precessing molecular jet signaling an obscured, growing supermassive black hole in NGC1377?
S. Aalto, F. Costagliola, S. Muller +11
With high resolution (0."25 x 0."18) ALMA CO 3-2 observations of the nearby (D=21 Mpc, 1"=102 pc), extremely radio-quiet galaxy NGC1377, we have discovered a high-velocity, very co…
Obscuring Fraction of Active Galactic Nuclei: Implications from Radiation-driven Fountain Models
Keiichi Wada
Active galactic nuclei (AGNs) are believed to be obscured by an optical thick "torus" that covers a large fraction of solid angles for the nuclei. However, the physical origin of t…
Concurrent Formation of Carbon and Silicate Dust in Nova V1280 Sco
Itsuki Sakon, Shigeyuki Sako, Takashi Onaka +12
We present infrared multi-epoch observations of the dust forming nova V1280 Sco over 2000 days from the outburst. The temporal evolution of the infrared spectral energy distr…
Outer Rotation Curve of the Galaxy with VERA III: Astrometry of IRAS 07427-2400 and Test of the Density-Wave Theory
Nobuyuki Sakai, Hiroyuki Nakanishi, Mitsuhiro Matsuo +6
We report the trigonometric parallax of IRAS 07427-2400 with VERA to be 0.185 0.027 mas, corresponding to a distance of 5.41 kpc. The result is consistent w…
