   Gracias Jaime...

Yo ya habia oido hablar de este proyecto hace algun tiempo y
no me habia vuelto a acordar de el, con el envio de ese texto
se me ha refrescado la memoria, Gracias...

Y por ello busque la pagina de el "National Cosmology SuperComputer"
que es como lo llaman esta es la direccion:

http://www.damtp.cam.ac.uk/cosmos/home.html

Es una pena que la parte dedicada a la parte teorica todavia este
bajo construccion:

COSMOS scientific results & publications (under development)

        The cosmic microwave sky 
        The early universe 
        Large-scale structure formation 
        Publications list 

Muy interesante...

Un Salu2...
