Abstract
Abstract We present CAPERS-LRD-z9, a little red dot (LRD) that we confirm to be a z = 9.288 broad-line active galactic nucleus (BLAGN). First identified as a high-redshift LRD candidate from PRIMER NIRCam photometry, follow-up NIRSpec/PRISM spectroscopy of CAPERS-LRD-z9 from the CANDELS-Area Prism Epoch of Reionization Survey (CAPERS) has revealed a broad 3500 km s −1 full width at half-maximum H β emission line and narrow [O iii ] λλ 4959, 5007 lines, indicative of a BLAGN. Based on the broad H β line, we compute a canonical black hole mass of log ( M BH / M ⊙ ) = 7.58 ± 0.15 , although full consideration of systematic uncertainties yields a conservative range of 6.65 < log ( M BH /…
