Finding bright $z\ge 6.6$ Lyman-$\alpha$ emitters with lensing: prospects for Euclid

Lucia Marchetti, Stephen Serjeant, Mattia Vaccari

We model the $z\ge 6.6$ Ly$\alpha$ luminosity function to estimate the number of lensed high$-z$ Ly$\alpha$ emitters that may be detected by the Euclid Deep Survey. To span the whole range…
