Ultra High Energy Comic Rays in the Cosmic Microwave Background
Ultra High Energy Comic Rays Cosmic Microwave Background
2011/10/13
We consider the propagation of ultra high energy cosmic rays (UHECR), for energies greater than E > 10^{14} eV but less than E < 10^{26} eV, in the cosmic medium of the Cosmic Microwave Background (CM...

Ultra-High Energy Cosmic Rays Galactic Magnetic Field
2011/10/8
We present a new method to search for heavy nuclei sources, on top of background, in the Ultra-High Energy Cosmic Ray data. We apply it to the 69 events with energies E>55 EeV published by the Pierre ...

A High Galactic Latitude HI 21cm-line Absorption Survey using the GMRT：II. Results and Interpretation
clouds kinematics and dynamics radio lines
2009/5/14
We have carried out a sensitive high-latitude (|b| > 15◦)
HI 21 cm-line absorption survey towards 102 sources using the GMRT.
With a 3σ detection limit in optical depth of ∼0.01, this is...
A High Galactic Latitude HI 21cm-line Absorption Survey using the GMRT：I. Observations and Spectra
clouds kinematics and dynamics radio lines
2009/5/14
We have used the Giant Meterwave Radio Telescope (GMRT)
to measure the Galactic HI 21-cm line absorption towards 102 extragalactic
radio continuum sources, located at high (|b| > 15◦) Galactic...
