UV slope of z$\sim$3 bright ($L>L^{\ast }$) Lyman-break galaxies in the COSMOS field

S. Pilo, M. Castellano, A. Fontana +7

We analyse a unique sample of 517 bright ($L>L^{\ast }$) LBGs at redshift z$\sim$3 in order to characterise the distribution of their UV slopes $\beta$ and infer their dust extinction unde…
