RIOJA. Environmental Effects on Stellar Populations and Ionized Gas in a Protocluster at

Wataru Osone, Takuya Hashimoto, Javier Álvarez-Márquez +23

Protoclusters in the epoch of reionization provide key laboratories for investigating how environment shapes early galaxy formation and evolution, and may also have contributed to…

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 …

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. Young Starburst and Ionized Gas Outflows in a Galaxy Uncovered by JWST NIRCam and NIRSpec Observations

Yi W. Ren, Akio K. Inoue, Javier Álvarez-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 (…

ELPIS: Accelerated metal and dust enrichment in a proto-cluster core at

Hideki Umehata, Yoichi Tamura, Yoshinobu Fudamoto +17

We present a study of the metal, dust, and molecular gas content in galaxies within the A2744-z7p9OD proto-cluster at z ~ 7.88. We focus on two galaxy groups, the Quintet and the C…
