In the report, we will discuss the value distribution of the modified Mellin transform of the square of the Riemann zeta-function introduced and studied by A.Ivic, M.Jutila and Y.Motohashi. We will recall its analytical properties as well as some estimates and mean square estimates. After this, we will state continuous and discrete limit theorems in the sense of weak convergence of probability measures on the complex plane and in the space of meromorphic functions for this transform. ...

Calculation of Atmospheric Emission Measured by Gregorian Feed Horns Paul F. Goldsmith September 16, 2001 As we use higher frequencies, emission from the Earth's atmosphere becomes more sig- ni cant. ... To use this program, you input the altitude, temperature, and precipitable water vapor (pwv) in mm. ... I have run the ATM code for several values of pwv with plausible temperature, and generated the zenith sky temperature as a function of frequency between 1 and 15 GHz. ...

... Clearly, what we need is big telescopes with high resolution spectrographs, to get good data on QSO absorption-lines. With bigger and better telescopes, you could measure the clustering and 3D distribution of gas in the early universe, by looking at lots of faint QSOs in the same parts of the sky. ... With the high resolutions made possible by big telescopes, you could look at the internal velocity structure of the absorbing clouds. ...
