Stochastic star formation activity of galaxies within the first billion years probed by JWST
C. Carvajal-Bohorquez, L. Ciesla, N. Laporte +8
In this work, we aim at characterizing the burstiness level of high-redshift galaxy SFHs and its evolution. We implement a stochastic SFH in CIGALE using PSD, to estimate the burst…
Clumpiness of galaxies revealed in the near-infrared with COSMOS-Web
Wilfried Mercier, Boris Sindhu Kalita, Marko Shuntov +30
Clumps in the rest-frame UV emission of galaxies have been observed for decades. Since the launch of the James Webb Space Telescope (JWST), a large population is detected in the re…
COSMOS-Web: A history of galaxy migrations over the stellar mass-star formation rate plane
R. C. Arango-Toro, O. Ilbert, L. Ciesla +39
The stellar mass-star formation rate (-) plane is a fundamental diagnostic for distinguishing galaxy populations. However, the evolutionary pathways of…
Reconstructing galaxy star formation histories from COSMOS2020 photometry using simulation-based inference
G. Aufort, C. Laigle, H. J. McCracken +6
We propose a novel method to reconstruct the full posterior distribution of the star formation histories (SFHs) of galaxies from broad-band photometry. Our method combines simulati…
