In a previous study from our group, th[...]texto impreso

Hempel, A. ; Cristobal Hornillos, D. ; Prieto, M. ; Trujillo, I. ; Balcells, M. ; López Sanjuan, C. ; Abreu, D. ; Eliche Moral, María del Carmen ; Domínguez Palmero, L. | Wiley | 2011-07We present a new catalogue of EROs from the Groth Strip and study the relation between their morphology and mass. With a selection criterion F814W?K_s? 4 and K_s? 21.0 we find 102 EROs, over a survey area of 155 arcmin^2, leading to a surface de[...]
