An Attenuation Bump at z=9.3: Probing Dust Diversity at Cosmic Dawn
Giulia Rodighiero, Santiago Álvarez-Córdoba, Michele Catone +46
We report the identification of a UV attenuation bump in the Black Pearl, a galaxy at a spectroscopic redshift of 9.3335 observed with JWST/NIRSpec as part of the ZENITH and EMBER…
Discovery of the Lyman- Forest in a Star-Forming Galaxy at : Implications for the Timing and Topology of Cosmic Reionization
Jakob M. Helton, Joris Witstok, Marta Laska +15
The escape of ionizing photons from galaxies during the Epoch of Reionization is often inferred indirectly because the intervening neutral hydrogen in the intergalactic medium (IGM…
Little Red Dots: One Photometric Tag Concealing Diverse Spectroscopic Flavors of Massive Star Formation and Black Hole Activity
Pablo G. Pérez-González, Guillermo Barro, Stefano Carniani +61
We compile JWST/NIRSpec prism and MIRI data for 249 Little Red Dots (LRDs) at 2.3<z<9.3, forming a representative spectroscopic subset of NIRCam-selected LRDs. We derive a median s…
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…
