Mauro Giavalisco
The exploration of the relation between galaxy sizes and other physical parameters has given important clues to understand the galaxy formation processes. We use the CANDELS Deep+Wide surveys in the GOODS-South, UDS and EGS fields, complemented by data from the HUDF09 program, to address the relation between size and luminosity at z\sim7. We select 153 z-band drop-out galaxies in six different fields characterized by a wide combination of depth and areal coverage, ideally suited to sample without biases the observed size-magnitude plane. Detailed simulations allow us to derive the completeness as a function of sizes and magnitudes and to quantify …
