The NIKA2 Cosmological Legacy Survey in COSMOS: Final 1.2mm and 2mm source catalogs and redshift distribution of dusty star-forming galaxies
C. R. Carvajal-Bohorquez, G. Lagache, A. Beelen +64
We present the final 1.2mm and 2mm source catalogs and the redshift distribution of the mm-selected population from the NIKA2 Cosmological Legacy Survey (N2CLS) in the COSMOS field…
Before its time: a remarkably evolved protocluster core at z=7.88
Callum Witten, Pascal A. Oesch, William McClymont +11
Protoclusters represent the most extreme environments in the very early Universe. They form from large-scale dark matter overdensities, harbouring an overabundance of galaxies fed…
The NIKA2 cosmological legacy survey at 2 mm: catalogs, colors, redshift distributions, and implications for deep surveys
M. Béthermin, G. Lagache, C. Carvajal-Bohorquez +54
Millimeter galaxy surveys are particularly effective in detecting dusty star-forming galaxies at high redshift. While such observations are typically conducted at ~1mm, some studie…
A systematic search for dormant galaxies at z~5-7 from the JWST NIRSpec archive
Alba Covelo-Paz, Corentin Meuwly, Pascal A. Oesch +6
JWST has revealed a population of ``dormant'' galaxies at that have recently halted their star formation and are characterized by weak emission lines and significant Balmer b…
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…
