Constraints on the X-ray luminosity function of AGN at <i>z</i> = 5.7โ6.4 with the Extragalactic Serendipitous Swift Survey
X-ray luminosity functions (XLFs) of Active Galactic Nuclei (AGN) trace the growth and evolution of supermassive black hole populations across cosmic time, however, current XLF models are poorly constrained at redshifts of z>6, with a lack of spectroscopic constraints at these high redshifts.
