PublicaciónAnisotropy measurements of the cosmic microwave background radiation at intermediate angular scales
Galaxy formation by gravitational instability implies the presence of temperature fluctuations in the cosmic microwave background. New observations at 10.45 and...

PublicaciónBar pattern speed at z∼1-2 to explore challenges of the Standard Cosmology
Stellar bars drive the galaxy secular evolution. While rotating around the galaxy centre with a given angular frequency, the bar pattern speed, they sweep...
