MIRI spectrophotometry of GN-z11: Detection and nature of an optical red continuum component

A. Crespo Gómez, L. Colina, P. G. Pérez-González +16

We present new MIRI F560W, F770W and F1000W imaging of GN-z11, extending the previous rest-frame coverage from 0.38 to 0.86m. We report significant detections (14) in the F56…
