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…
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. Dusty outflows and density-complex ISM in the N-enhanced lensed galaxy RXCJ2248-ID at z=6.1
A. Crespo Gómez, Y. Tamura, L. Colina +19
We present an analysis on the kinematics and physical properties of the ionized gas in the lensed galaxy RXCJ2248-ID at z=6.1 based on high-resolution JWST NIRSpec/IFU data in comb…
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 (…
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…
Early massive galaxy formation in the core of a galaxy protocluster 650 million years after the Big Bang
Yoshinobu Fudamoto, Yurina Nakazato, Daniel Ceverino +24
Rest-frame optical observations with the James Webb Space Telescope (JWST) have uncovered a population of massive galaxies, exceeding solar masses, present less than a bi…
