High-ionization coronal lines trace quasar-like activity in recently quenched galaxies at high redshift
F. Valentino, K. Ito, M. Farcy +31
We report the detection of the high-ionization line [NeV]3427 in the JWST/NIRSpec archival spectra of 6 massive quenched galaxies at , identified from a parent s…
DeepDive: Simultaneous Formation of Massive Quiescent Galaxies in High-Redshift Galaxy Overdensities
Takumi Kakimoto, Masayuki Tanaka, Kei Ito +20
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…
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,…
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…
Molecular gas excitation in the circumgalactic medium of MACS1931-26
L. Ghodsi, J. Zhou, P. Andreani +6
The evolution of galaxies is largely affected by exchanging material with their close environment, the circumgalactic medium (CGM). In this work, we investigate the CGM and the int…
Broad-line region geometry from multiple emission lines in a single-epoch spectrum
L. Kuhn, J. Shangguan, R. Davies +17
The broad-line region (BLR) of active galactic nuclei (AGNs) traces gas close to the central supermassive black hole (BH). Recent reverberation mapping (RM) and interferometric spe…
Faint [CI](1-0) emission in z 3.5 radio galaxies
S. Kolwa, C. De Breuck, J. Vernet +6
We present Atacama Large Millimeter/sub-millimeter Array (ALMA) neutral carbon, [C I](1-0), line observations that probe molecular hydrogen gas (H) within seven radio galaxies…
