A Detailed Study on the Range Fluctuations of $10^{11}$eV to $10^{18}$eV Muons in Water and the Fluctuations of the Cherenkov Lights due to the Accompanied Cascade Showers initiated by Muons
the Range Fluctuations the Cherenkov Lights
2011/1/10
The validity of our Monte Carlo simulation procedure ({\it the integral method}) had been verified by the corresponding analytical procedure of which is quite independent of our method methodologicall...
Formation of Early Water Oceans on Rocky Planets

2010/11/15
Terrestrial planets, with silicate mantles and metallic cores, are likely to obtain water and
carbon compounds during accretion. Here I examine the conditions that allow early formation of a surface ...
Two Epochs of Very Large Array Observations of Water Maser Emission in the active galaxy NGC 6240
galaxies active - galaxies individual (NGC 6240) - galaxies ISM - ISM - galaxies nuclei masers
2010/11/12
Studies of 22GHz H2O maser emission from the merging galaxy NGC 6240 with double nuclei are presented. Two epochs of Very Large Array (VLA) obser-vations in the A-configuration in spectral-line mode w...
Distribution of Water Vapor in Molecular Clouds

2010/11/16
We report the results of a large-area study of water vapor along the Orion Molecular Cloud ridge, the purpose of which was to determine the depth-dependent distribution of gas-phase water in dense mol...
The Determination of the Water Vapor Content in the Pulkovo VKM-100 Multipass Vacuum Cell Using Polymer Sensors of Humidity
Instrumentation and Methods for Astrophysics (astro-ph.IM)
2011/1/7
In spectral studies of water vapor under laboratory conditions (determination of molecular constants, measurement for spectral transmission functions), the amount of water vapor in the time of the mea...
A Laboratory Study of Absorbing Capacity of Water Vapor at the Wavelengths from 6500 TO 10500 Å
Instrumentation and Methods for Astrophysics (astro-ph.IM)
2011/1/7
We obtained laboratory spectra of absorption by water vapor at the wavelengths 6500-10500 {\AA} with the multipass cell. The water vapor content along the line of view varied from 0.1 to 3.0 cm of pre...
The Laboratory Complex for the Calibration of Photometers Using the Optical Method for Determination of the Water Vapor Content in the Earth Atmosphere
Instrumentation and Methods for Astrophysics (astro-ph.IM)
2011/1/7
We describe the laboratory complex for the calibration of photometers that are used in weather service to measure the water vapor content in the Earth atmosphere.
Photochemistry in the inner layers of clumpy circumstellar envelopes: formation of water in C-rich objects and of C-bearing molecules in O-rich objects
Galaxy Astrophysics (astro-ph.GA)
2010/12/28
A mechanism based on the penetration of interstellar ultraviolet photons into the inner layers of clumpy circumstellar envelopes around AGB stars is proposed to explain the non-equilibrium chemistry o...
Fluctuation of TeV to EeV Energy Muons and Induced Muon Showers in Water
High Energy Astrophysical Phenomena (astro-ph.HE)
2010/12/27
By using the integral method in the muon propagation through water, we calculate the range fluctuation of high and ultra high energy muons. Many authors divide all radiative processes into two parts, ...
