Abstract:
We present the detection of 145 extended Lyman-alpha haloes around
individual high-z (3-6) star-forming galaxies in the UDF field
observed by MUSE/VLT. Using a 2D, two-component (continuum-like and
halo) decomposition of Lyman-alpha emission assuming circular
exponential distributions, we measure scale lengths and luminosities
of Lyman-alpha haloes.
Description:
Fitted parameters, measurements and general properties of the 145
Lyman-alpha emitters surrounded by a halo in the MUSE UDF data.
