We report the first detection of submillimeter water maser emission toward water-fountain nebulae, which are post-AGB stars that exhibit high-velocity water masers. Using APEX we found emission in the ortho-H2O (1029 → 936) ...

The most powerful water maser feature ever seen in Orion was monitored for seven years. The maser reached a peak flux density of about 6.7 x 10 to the 6th Jy. The total radiated energy between August 1979 and June 1987 was ...

We present a multiwavelength study of five methanol maser sites which are not directly associated with a strong (>100 mJy) radio continuum source: G31.28+0.06, G59.78+0.06, G173.49+2.42 (S231, S233IR), G188.95+0.89 ...

Using the open photoacoustic cell technique, we obtained the spectra of the photoacoustic signal amplitude as a function of the modulation frequency of the incident radiation. From these spectra we determined the thermal ...
