Challenging the Active Galactic Nucleus Scenario for JWST/NIRSpec Little Red Dot and Non–Little Red Dot Broad Hα Emitters in Light of Nondetection of NIRCam Photometric Variability and X-Ray
JWST has uncovered a substantial population of high- z ( z ≳ 4) galaxies exhibiting broad H α emission lines with a full width at half-maximum exceeding 1000 km s ^−1 . This population consists of a well-known subset called little red dots (LRDs) and the remaining non-LRDs. If all of these broad H...
