Se presenta el mapa de la radiación de la galaxia a 2300 MHz, producido con los datos obtenidos durante la estadía del radiotelescopio GEM en Colombia. Se halla a dependencia del índice espectral de la radiación de la galaxia con la latitud galáctica en la banda o ervable desde Villa de Leyva (Boyacá) se construye un mapa de la radiación de la galaxia a 53 GHz a través e un escalamiento del mapa de Haslam a 408 MHz utilizando la forma del índice espectral hallada. Se estima el valor del cuadripolo co mológico a partir del cuadripolo en los mapas, a 53 GHz, de COBE y de la radiación de la galaxia. Con el cuadripolo cosmológico hallado se cálcula una cota observaciona a la velocidad angular de rotación global del universo y la orientación del eje e dicha rotación.
We present the galactic radiation map at 2300 MHz, produced with the data taken during the Colombian expedition of the GEM radiotelescope. The dependence of the galactic radiation spectral index with the galactic latitude is found over the sky band observable from Villa de Leyva (Boyacá) and is used to build a galactic radiation map at 53 GHz by scaling the Haslam 408 MHz map.
This 53 GHz map along with the COBE one at the same frequency are used to estímate the cosmic quadrupole as well as the galactic one. Finally we obtain an observational upper limit to a posible angular rotation velocity of the universe and the orientation of the rotation axis.
