The ALPINE-CRISTAL-JWST Survey: The Fast Metal Enrichment of Massive Galaxies at z~5

Andreas L. Faisst, Lun-Jun Liu, Yohan Dubois +54

We present the stellar mass-metallicity relation (MZR) and mass-metallicity-star formation relation ("fundamental metallicity relation"; FMR) of 18 massive (log(M/Msun) = 9.5 - 11)…

The ALPINE-CRISTAL-JWST Survey: JWST/IFU Optical Observations for 18 Main-Sequence Galaxies at z=4-6

A. L. Faisst, S. Fujimoto, A. Tsujita +80

To fully characterize the formation and evolution of galaxies, we need to observe their stars, gas, and dust on resolved spatial scales. We present the ALPINE-CRISTAL-JWST survey,…

Active galactic nuclei-heated dust revealed in "little red dots"

I. Delvecchio, E. Daddi, B. Magnelli +11

Little red dots (LRDs) are a puzzling population of extragalactic sources whose origin is highly debated. In this {work}, we performed a comprehensive stacking analysis of NIRCam,…

The observed total star formation rate function up to z \sim 6: complementary UV and IR contributions and comparison with state-of-the-art galaxy formation models

A. Traina, C. Gruppioni, I. Delvecchio +21

We investigate how the obscured IR-derived and the dust-corrected UV star formation rate functions (SFRFs) compare with each other, and with predictions from state-of-the-art theor…

The ALPINE-CRISTAL-JWST survey: spatially resolved star formation relations at

C. Accard, M. Béthermin, M. Boquien +37

Star formation governs galaxy evolution, shaping stellar mass assembly and gas consumption across cosmic time. The Kennicutt-Schmidt (KS) relation, linking star formation rate (SFR…

Spatially resolved [CII]-gas conversion factor in early galaxies

L. Vallini, A. Pallottini, M. Kohandel +12

Determining how efficiently gas collapses into stars at high-redshift is key to understanding galaxy evolution in the Epoch of Reionization (EoR). Globally, this process is quantif…
