The $z \gtrsim 9$ galaxy UV luminosity function from the JWST Advanced Deep Extragalactic Survey: insights into early galaxy evolution and reionization

Understand

The high-redshift UV luminosity function provides important insights into the evolution of early galaxies.

• JWST has revealed an unexpectedly large population of bright ($M_\mathrm{UV} \lesssim -20$) galaxies at $z\gtrsim10$, implying fundamental changes in the star forming properties of galaxies at increasingly early times.
• However, constraining the fainter population ($M_\mathrm{UV} \gtrsim -18$) has been more challenging.
• In this work, we present the $z\gtrsim9$ UV luminosity function from the JWST Advanced Deep Extragalactic Survey.
