The aim of the project is to contribute to the characterisation of the spectral energy distribution of the coolest brown dwarfs discovered to date, the Y dwarfs.We obtained z-band far-red imaging for six Y dwarfs and a T9+Y0 binary with the OSIRIS (Optical System for Imaging and low Resolution Integrated Spectroscopy) instrument on the 10.4-m Gran Telescopio de Canarias (GTC).We detect five of the seven known Y dwarfs in the z-band, infer theioptical-to-infrared colours, and measure their proper motions. We find a higher dispersion in the z-J and z-H colours of Y0 dwarfs than in T dwarfs

Recent observations with the GTC take us a step closer to conditions in the early Universe

The project, carried out with the OSIRIS camera of the Gran Telescopio CANARIAS, has undertaken the deepest and most detailed census of the massive supercluster Cygnus OB2, one of the largest and nearest known 'nurseries' of stars

The new connection for the RedIRIS-NOVA and the Canarian R+D+i network is now established
