Pumping of OH Main-Line Masers in Star-Forming Regions
Pumping routes of masers can in principle be recovered from a small matrix of master equations, at an advanced stage of elimination, by tracing back the coefficients to a set of unmodified all-process rate coefficients, drawn from those which appeared in the original set of master equations, prior to any elimination operations. The traceback is achieved by logging the operations carried out on ...
متن کاملUbiquitous Water Masers in Nearby Star-forming Galaxies
We report the detection of water maser emission from four nearby galaxies hosting ultradense H II (UDHII) regions, He 2-10, the Antennae galaxies (NGC 4038/4039), NGC 4214, and NGC 5253, with the Green Bank Telescope. Our detection rate is 100%, and all of these H2O “kilomasers” (LH2O < 10 L⊙) are located toward regions of known star formation as traced by UDHII regions and bright 24 μm emissio...
متن کاملStatistical Analysis of Water Masers in Star-forming Regions: Cepheus a and W75 N
We have done a statistical analysis of Very Long Baseline Array (VLBA) data of water masers in the star-forming regions (SFRs) Cepheus A and W75 N, using correlation functions to study the spatial clustering and Doppler-velocity distribution of these masers. Two-point spatial correlation functions show a characteristic scale size for clusters of water maser spots .1 AU, similar to the values fo...
متن کاملWater in star- and planet-forming regions.
In this paper, we discuss the astronomical search for water vapour in order to understand the disposition of water in all its phases throughout the processes of star and planet formation. Our ability to detect and study water vapour has recently received a tremendous boost with the successful launch and operation of the Herschel Space Observatory. Herschel spectroscopic detections of numerous t...
متن کاملObservations of Massive Star Forming Regions with Water Masers: Mid-infrared Imaging
We present here a mid-infrared imaging survey of 26 sites of water maser emission. Observations were obtained at the InfraRed Telescope Facility 3-m telescope with the University of Florida mid-infrared imager/spectrometer OSCIR, and the JPL mid-infrared camera MIRLIN. The main purpose of the survey was to explore the relationship between water masers and the massive star formation process. It ...
