There and back again? Neutral outflows in z~3.5 quiescent galaxies

Pengpei Zhu, Kei Ito, Francesco Valentino +16

Neutral gas outflows play a crucial role in the baryon cycle of galaxies, their properties provide key insights into the transition from star formation to quiescence. In this work,…

DeepDive: Simultaneous Formation of Massive Quiescent Galaxies in High-Redshift Galaxy Proto-clusters

Takumi Kakimoto, Masayuki Tanaka, Kei Ito +19

We report on the spectroscopic confirmation of overdense regions of massive quiescent galaxies (QGs) in the early Universe with JWST/NIRSpec. Based on data from the DeepDive NIRSpe…

Warm and cold molecular gas in the cluster center of MACS 1931-26 with JWST and ALMA

L. Ghodsi, L. Kuhn, A. W. S. Man +9

We perform one of the first spatially resolved studies of warm (100 K) and cold (10-100 K) molecular gas in the circumgalactic medium (CGM), focusing on the brightest cluster ga…

Extended multi-phase gas reservoirs in the z=4.3 protocluster SPT2349-56: non-stellar ionisation sources?

Kevin C. Harrington, Amit Vishwas, Allison W. S. Man +4

We aim to characterize the multi-phase gas in the SPT2349-56 protocluster at z=4.3, known to host one of the most starbursting and AGN-rich high redshift environments.For this purp…

Molecular gas mass measurements of an active, starburst galaxy at using ALMA observations of the [CI], CO and dust emission

Hao-Tse Huang, Allison W. S. Man, Federico Lelli +7

We present new ALMA observations of a starburst galaxy at cosmic noon hosting a radio-loud active galactic nucleus: PKS 0529-549 at . To investigate the conditions of its c…
