Luke-warm dark matter: Bose-condensation of ultra-light particles
Luke-warm dark matter ultra-light particles
2010/3/18
We discuss the thermal evolution and Bose condensation of ultra-light scalar particles with Compton wavelength of galactic scales. We find an upper bound of 1.5 K for the dark matter temperature from ...

Comet ice luminescence frozen hydrocarbon particles unidentified lines
2009/5/12
The possible nature of unidentified cometary emissions is
under discussion.We propose a new model of the ice particles in cometary
halos as a mixture of frozen polycyclic aromatic hydrocarbons and a...
