Probing the large-scale structure with 21cm-galaxy cross-bispectrum: Estimates from simulations and forecasts for upcoming cosmological surveys

Leon Noble, Suman Majumdar, Matteo Viel +7

The paper investigates the 21 cm–galaxy cross‑bispectrum using simulated galaxy evolution models and forecasts its detectability with upcoming Euclid‑like galaxy surveys and SKA‑Mi…

HI Simulations for Cosmology with the SKA Observatory

Tommaso Ronconi, Gabriella De Lucia, Marta Spinelli +15

We present a comparative overview of state-of-the-art methods for modelling the distribution of neutral hydrogen (HI) in the post-reionization Universe, developed in preparation fo…

Limited imprint of high-mass IMF variations on sodium abundances in main-sequence galaxies

Ziyi Guo, Donatella Romano, Zhiqiang Yan +10

Growing evidence suggests that the stellar initial mass function (IMF) varies systematically across galaxies, deviating from the canonical Milky Way form. Such variations would mod…

Cosmic web stripping and starvation of low-mass filament galaxies in TNG50

Daria Zakharova, Gabriella De Lucia, Benedetta Vulcani +3

Galaxy properties are known to correlate with their location within the cosmic web. However, the role of filaments remains poorly understood, particularly for low-mass galaxies, wh…

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)…

A census of quiescent galaxies across with JWST/MIRI: Mass-dependent number density evolution of quiescent galaxies in the early Universe

Tiancheng Yang, Tao Wang, Ke Xu +12

Recent JWST observations have revealed a large population of quiescent galaxies (QGs) at high redshift (), challenging current models of early galaxy formation and quen…
