Characterisation of the non-Gaussianity of radio and IR point-sources at CMB frequencies
ology: Cosmic Microwave Background, large scale structures Galaxiesstatistics, Infrared: galaxies Radio continuum: galaxies Methods: statistical
2011/10/8
The present study focuses on the characterisation of the non-Gaussianity produced by radio point-sources and, for the first time, by infrared sources in the frequency range of the CMB from 30 to 350 G...

2010/11/12
Measurement of redshifted 21-cm emission from neutral hydrogen promises to be the most e ective method for studying the reionisation history of hydrogen and,indirectly, the rst galaxies. These studie...

We have analyzed data from a multi-site campaign to observe oscillations in the F5 star Procyon. The data consist of high-precision velocities that we obtained over more than three weeks with eleven t...
GUIDING OF WHISTLER-MODE WAVES WITH FREQUENCIES ABOVE ONE HALF OF THE GYROFREQUENCY IN THE MAGNETOSPHERE
WHISTLER-MODE WAVES GYROFREQUENCY MAGNETOSPHERE FREQUENCIES
2009/3/19
Ray-tracing calculations show that a trough, L = 4.6, located
in the region outside the plasmapause is capable to guide whistler-mode waves in
frequency range 0.5fBmin−0.64fBmin, from one hemi...
THE ANALYSIS OF THE POSSIBLE THERMAL EMISSION AT RADIO FREQUENCIES FROM AN EVOLVED SUPERNOVA REMNANT HB 3 (G132.7+1.3)：REVISITED
Radiation mechanisms thermal-Radio continuum general-ISM supernova remnants-ISM individual objects HB3
2009/1/19
It has recently been reported that some of the °ux density values
for an evolved supernova remnant (SNR) HB 3 (G132.7+1.3) are not accurate
enough. In this work we therefore revised the analysis of ...
