Maser Emission toward the Infrared Dark Cloud G359.94+0.17 Seen in Silhouette against the Galactic Center
S. Deguchi, D. Tafoya, N. Shino
The infrared dark cloud G359.94+0.17 is a conspicuous, opaque cloud, which is seen in silhouette against the Galactic center. We found unexpectedly strong (~50 Jy) maser emission o…
A molecular cloud within the light echo of V838 Monocerotis
T. Kamiński, R. Tylenda, S. Deguchi
Context. V838 Mon is an eruptive variable, which exploded in 2002. It displayed the most spectacular light echo ever observed. However, neither the origin of the reflecting matter…
SiO Maser Spectra of V407 Cyg after the 2010 March Nova Outburst
S. Deguchi, K. Koike, N. Kuno +3
We report on the time variation of SiO maser emission from the symbiotic stellar system V407 Cyg after the classical nova outburst on 2010 March 10. Although both the SiO --0…
SiO and H2O Maser Observations of Red Supergiants in Star Clusters Embedded in the Galactic Disk
S. Deguchi, J. Nakashima, Y. Zhang +3
We present the result of radio observations of red supergiants in the star cluster, Stephenson's #2, and candidates for red supergiants in the star clusters, Mercer et al. (2005)'s…
CO in OH/IR stars close to the Galactic centre
A. Winnberg, S. Deguchi, M. J. Reid +3
Aims: A pilot project has been carried out to measure circumstellar CO emission from three OH/IR stars close to the Galactic centre. The intention was to find out whether it would…
Observations of Stellar Maser Sources with no IRAS Counterpart
S. Deguchi, J. Nakashima, T. Miyata +1
We investigated stellar maser sources with no IRAS counterpart at the radio, middle-infrared, and near-infrared wavelengths. A 43 GHz SiO maser search for 120 2MASS/MSX objects, an…
