An unambiguous AGN and a Balmer break in an Ultraluminous Little Red Dot at z=4.47 from Ultradeep UNCOVER and All the Little Things Spectroscopy

Ivo Labbe, Jenny E. Greene, Jorryt Matthee +37

We present a detailed exploration of the most optically-luminous Little Red Dot (erg/s, erg/s, F444W=22AB) found to date. Located in the Abell 2744 fie…
