Water Masers as an Early Tracer of Star Formation [PDF]
The Astrophysical Journal Supplement Series, 2022 Abstract We present a study of the correlation between 22 GHz water maser emission and far-infrared/submillimeter (IR/sub-mm) sources. The generalized linear model (GLM) is used to predict H2O maser detection in a particular source with defined physical parameters.

Water maser emission in IC 342 [PDF]
Astronomy & Astrophysics, 2002 The detection of 22 GHz water vapor emission from IC342 is reported, raising the detection rate among northern galaxies with 100 micron IRAS point source fluxes > 50 Jy to 16%. The maser, associated with a star forming region 10-15 arcsec west of the nucleus, consists of a single 0.5 km/s wide feature and reaches an isotropic luminosity of 0.01 ...

WATER MASERS IN THE ANDROMEDA GALAXY. II. WHERE DO MASERS ARISE? [PDF]
The Astrophysical Journal, 2016 ABSTRACT We present a comparative multiwavelength analysis of water-maser-emitting regions and non-maser-emitting luminous 24 μm star-forming regions in the Andromeda Galaxy (M31) to identify the sites most likely to produce luminous water masers useful for astrometry and proper motion studies.

Online Database of Multiwavelength Water Masers in Galactic Star-Forming Regions [PDF]
, 2022 In this paper, we present an online multiwavelength database of water masers in star-forming regions of the Galaxy. The collected data represent 1/495% of all observations of water masers in star-forming regions published since 1989. Nineteen transitions

WATER MASERS IN THE ANDROMEDA GALAXY. I. A SURVEY FOR WATER MASERS, AMMONIA, AND HYDROGEN RECOMBINATION LINES [PDF]
The Astrophysical Journal, 2016 ABSTRACT We report the results of a Green Bank Telescope survey for water masers, ammonia (1, 1) and (2, 2), and the H66α recombination line toward 506 luminous compact 24 μm emitting regions in the Andromeda Galaxy (M31). We include the 206 sources observed in the Darling water maser survey for completeness.

Submillimeter H2O masers in water-fountain nebulae [PDF]
, 2014 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 (10(29) -> 9(36)) transition at 321.226 GHz

Probing AGN with Water Masers [PDF]
Symposium - International Astronomical Union, 1996 Observations of the angular distribution of the water masers in the nucleus of NGC4258 reveal the presence of a thin molecular disk in nearly perfect Keplerian orbit (Miyoshi et al., 1995; Moran et al., 1995). About 300 galaxies have been searched for nuclear water masers to a limiting sensitivity of about 0.1 Jy (e.g., Braatz, 1996); and 16 masers ...
