Dissecting the Obscured Core of GN20: an Active Galactic Nucleus Outshone by Young Stars

M. Hamed, L. Colina, P. G. Pérez-González +17

We investigate the relative contributions of star formation and AGN activity to the total energy budget of GN20, one of the most luminous dusty star-forming galaxies known at

MIDIS: The identification of deep MIRI-red sources as candidates for extreme Balmer-break and line emitting galaxies at high-z

I. Jermann, G. Brammer, S. Gillman +27

We investigate the detection and nature of 5.6~μm MIRI-red sources in the MIRI Deep Imaging Survey (MIDIS), covering 2.4~arcmin in the Hubble Ultra Deep Field. MIDIS is the de…

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 F…

Spatially resolved H emission in B14-65666: compact starbursts, ionizing efficiency and gas kinematics in an advanced merger at the Epoch of Reionization

C. Prieto-Jiménez, J. Álvarez-Márquez, L. Colina +28

We present MIRI/JWST medium resolution spectroscopy (MRS) and imaging (MIRIM) of B14-65666, a Lyman-break and interacting galaxy at redshift =7.15. We detect the H line emis…

MIDIS. Near-infrared rest-frame morphology of massive galaxies at in the Hubble eXtreme Deep Field

L. Costantin, S. Gillman, L. A. Boogaard +29

Thanks to decades of observations using the Hubble Space Telescope (HST), the structure of galaxies at redshift has been widely studied in the rest-frame ultraviolet regime,…
