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 p…

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…

There Is More to Outshining: 2D Dust Effects on Stellar Mass Estimates at with JWST in the JADES Field

M. Hamed, P. G. Pérez-González, M. Annunziatella +15

Dust attenuation modifies the observed spectral energy distribution (SED), leading to biases in the properties inferred from integrated SED fitting. As spatially resolved SED model…
