Dense cores inside interstellar clouds do shine: a widespread phenomenon
The emission of diffuse light in the mid infrared from interstellar cloud dense cores has been searched thoroughly in the Galaxy. This emission, named...
Exploring the epoch of reionization through the 21 cm radiation
After the Big-bang, the Universe experienced a dark age, just after the hydrogen atoms recombined, and before the first sources (stars and quasars) could...
The Spite plateau exists also in other galaxies: the case of omega Centauri
For over twenty years the lithium abundance in old stars (the Spite plateau) has been considered a primary indicator of the baryonic density of the Universe,...
