Discovery of a Lyα blob photo-ionised by a super-cluster of massive stars associated with a z = 3.49 galaxy

Aims. We report the discovery and characterisation of a Lyman α (Lyα) blob close to a galaxy at redshift z = 3.49. We present the analysis we performed to check whether the companion galaxy could be the source of the ionised photons responsible for the Lyα emission from the blob.
