Model-independent reconstruction of UV luminosity function and reionization epoch

Hazra, Dhiraj Kumar; Adak, Debabrata; Mitra, Sourav +1 more

We conduct a first comprehensive study of the Luminosity Function (LF) using a non-parametric approach. We use Gaussian Process to fit available luminosity data between redshifts z ∼ 2-8. Our free-form LF in the non-parametric approach rules out the conventional Schechter function model to describe the abundance-magnitude relation at redshifts z=3…
