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 …
The dynamics of the Anglerfish cluster
B. Destefanis, M. Balboni, I. Bartalucci +8
Merging galaxy clusters represent the ideal laboratory to test our understanding of the large scale structure formation history and the processes involved. While many merging clust…
MIDIS: Strong H+[OIII] Line Emitters at
Thomas R. Greve, Steven Gillman, Pierluigi Rinaldi +24
We present a search for strong H+[O III] emitters at in the HUDF using ultra-deep JWST/MIRI F560W imaging from the MIDIS survey. Three galaxies are identified via…
JWST Reveals Two Overmassive Black Hole Candidates in Dwarf Galaxies at z 0.7: Pushing Black Hole Searches into the Dwarf-Galaxy Regime
E. Iani, P. Rinaldi, A. Torralba +35
We report the discovery and characterization of two compact galaxies, Pelias and Neleus, at z ~ 0.71 and z ~ 0.75, identified in MACS J0416.1-2403 and GOODS-North. Both exhibit unu…
Radio selection of heavily obscured AGN in the J1030 field: unraveling a missing Compton-thick population
Giovanni Mazzolari, Roberto Gilli, Marco Mignoli +21
We tested the effectiveness of radio selection to discover heavily obscured AGNs, particularly at high-z, and we measured their abundance for the first time from a radio perspectiv…
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…
