Probing cold gas and dust in quiescent galaxies across cosmic time

Anita Zanella, Sirio Belli, Belen Alcalde Pampliega +35

The discovery of massive quiescent galaxies at high redshift by JWST has revealed that star formation can cease rapidly in the early Universe, yet the physical mechanisms responsib…

The Role of Environment in Shaping the Assembly Timelines of Massive Quiescent Galaxies at Cosmic Noon

Tianmu Gao, J. Trevor Mendel, Letizia Bugiani +10

JWST observations of massive quiescent galaxies (MQGs) at have revealed diverse star formation histories (SFHs). In this letter, we investigate whether these variations ar…

Galactic Outflows and Star-Formation Quenching: A JWST Perspective

Rebecca L. Davies, Sirio Belli

Outflows driven by active galactic nuclei (AGN) are widely considered a key mechanism for regulating and quenching star formation in massive galaxies. However, direct observational…

Euclid Quick Data Release (Q1). Exploring the complexity of quenching processes across time, environment, and mass through recently quenched galaxies

Euclid Collaboration, Z. Mao, L. Pozzetti +308

Recently quenched galaxies (RQGs) provide insights into galaxy quenching. We present a photometric and spectroscopic analysis of RQGs using the first Euclid Quick Data Release (Q1)…

GREX-PLUS Science Book v2

PLUS Science Team, Shunsuke Baba, Sirio Belli +52

GREX-PLUS (Galaxy Reionization EXplorer and PLanetary Universe Spectrometer) is a mission candidate for a JAXA strategic L-class mission to be launched in the 2030s. Its primary sc…

Outflows in the Early Universe: Neutral gas Absorption in Galaxies at z > 3 from low-resolution JWST Spectroscopy

Matteo Sapori, Sirio Belli, Letizia Bugiani +14

Recent JWST/NIRSpec observations have shown that Na I D absorption tracing neutral gas outflows is widespread in massive galaxies at Cosmic Noon (-), but their prevalenc…
