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…
X-ray stellar feedback in low-metallicity starbursts: Insights from the template starburst galaxy ESO 338-IG04 and its halo
M. Chatzis, L. M. Oskinova, S. Reyero Serantes +7
The X-ray output of low-metallicity starburst galaxies is a key component of stellar feedback, tracing the processes responsible for gas ionization and chemical enrichment. The int…
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…
MIDIS: Unveiling the Star Formation History in massive galaxies at with spectro-photometric analysis
M. Annunziatella, P. G. Pérez-González, J. Ãlvarez-Márquez +23
We investigate the star formation histories (SFHs) of a sample of massive galaxies () in the redshift range . We analyze spectro-photo…
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. Ãlvarez-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…
