Star formation quenching precedes morphological transformation in COSMOS-WEB's richest galaxy groups

Z. Ghaffari, G. Gozaliasl, A. Biviano +26

We analyzed the 25 richest galaxy groups in COSMOS-Web at z = 0.18-3.65, identified via the AMICO algorithm. These groups contain 20-30 galaxies with high (>75%) membership probabi…

EMU and Euclid: Detection of a radio-optical galaxy clustering cross-correlation signal between the Evolutionary Map of the Universe and Euclid

G. Piccirilli, B. Bahr-Kalus, S. Camera +173

Synergies between large-scale radio-continuum and optical/near-infrared galaxy surveys are a powerful tool for cosmology. Cross-correlating these surveys can constrain the redshift…

Euclid preparation. Establishing the quality of the 2D reconstruction of the filaments of the cosmic web with DisPerSE using Euclid photometric redshifts

Euclid Collaboration, N. Malavasi, F. Sarron +313

Cosmic filaments are prominent structures of the matter distribution of the Universe. Modern detection algorithms are an efficient way to identify filaments in large-scale observat…

Quantitative analysis of the molecular gas morphology in nearby disk galaxies

Takashi Yamamoto, Daisuke Iono, Toshiki Saito +4

We present a quantitative and statistical analysis of the molecular gas morphology in 73 nearby galaxies using high spatial resolution CO ( = 2-1) data obtained from the Atacama…
