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 …
Extremely UV-bright starbursts at the end of cosmic reionization
R. Marques-Chaves, D. Schaerer, M. Dessauges-Zavadsky +22
We present a study of 27 very UV-bright (-22.0<MUV<-24.4) sources at z~6 identified in SHELLQs survey. Stacking their rest-frame UV spectra reveals a prominent NV1240A P-Cygni, con…
Near-infrared diagnostic diagrams of the gas ionization sources in nearby galaxies: a JWST NIRSpec view
J. H. Costa-Souza, Luis Colina, Rogemar A. Riffel +6
Buried active galactic nuclei and obscured young stellar clusters pose significant challenges to traditional optical diagnostic diagrams. Therefore, developing new tools to trace t…
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…
RIOJA. A Clumpy Galaxy Assembly at Redshift 6.81 Revealed by JWST
Ken Mawatari, Luca Costantin, Mitsutaka Usui +21
Spatially resolved multi-wavelength analysis is essential to study galaxy formation and evolution. A UV-bright galaxy COS-2987030247 at is one of the Rosetta Stones in t…
RIOJA. Young Starburst and Ionized Gas Outflows in a Galaxy Uncovered by JWST NIRCam and NIRSpec Observations
Yi W. Ren, Akio K. Inoue, Javier Ãlvarez-Márquez +21
We present analysis of JWST NIRCam and NIRSpec observations of the galaxy SXDF-NB1006-2 at , as part of the Reionization and the ISM/Stellar Origins with JWST and ALMA (…
