MEGA: Spectrophotometric Spectral Energy Distribution Fitting of Little Red Dots Detected in JWST MIRI

We analyze eight spectroscopically confirmed little red dots (LRDs) at redshifts z  = 5.1–8.7 with JWST/NIRCam, NIRSpec, and MIRI data. The LRDs have red NIRCam colors, F150W − F444W > 1, but flat NIRCam − MIRI colors, −0.5 < F444W − F770W < 0.5, suggesting weak warm/hot dust components. The LRDs ha...
