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…
The ionised interstellar medium of DSFGs revealed by JWST/NIRSpec and ALMA: Super-solar metallicity, low ionisation parameters and, typical electron densities
Steven Gillman, Kei Ito, Francesco Valentino +25
We present a detailed study of near-infrared (2-4m) JWST/NIRSpec spectra of 48 high-redshift () galaxies detected with ALMA at . From a multi-wa…
DeepDive: Tracing the early quenching pathways of massive quiescent galaxies at from their star-formation histories and chemical abundances
Massissilia L. Hamadouche, Katherine E. Whitaker, Francesco Valentino +21
We investigate the chemical abundances and star-formation histories (SFH) of ten massive () quiescent galaxies at usi…
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,…
The ALMaQUEST Survey XVII: Unveiling Multiple Quenching Pathways in Green Valley Galaxies via Molecular Gas and Quenching Timescale Analyses
Lihwai Lin, Po-Feng Wu, Mallory D. Thorp +6
Statistically, green valley (GV) galaxies exhibit lower molecular gas fractions () and reduced star formation efficiency (SFE) compared to star-forming galaxies. However,…
Exploring the Origin of Rejuvenating Gas from MaNGA Nearby Galaxies
Ting-Hsuan Li, Po-Feng Wu
This study investigates the origin of secondary star formation, i.e., rejuvenation in nearby galaxies. From the MaNGA IFU survey, we use stellar absorption features, D4000 and…
A MUltiwavelength Study of ELAN Environments (AMUSE): The Impact of Dense Environment on Massive Dusty Star-Forming Galaxies at Cosmic Noon
Yu-Jan Wang, Chian-Chou Chen, Fabrizio Arrigoni Battaia +3
To understand how massive galaxies are influenced by their surroundings, we present new ALMA and NOEMA observations as part of A MUltiwavelength Study of ELAN Environments (AMUSE$^…
Unusually High Gas-to-Dust Ratios Observed in High-Redshift Quiescent Galaxies
Justin S. Spilker, Katherine E. Whitaker, Desika Narayanan +15
Tracking the cold molecular gas contents of galaxies is critical to understand the interplay between star formation and galaxy growth across cosmic time. Observations of the long-w…
No Evidence of a Dichotomy in the Elliptical Galaxy Population
Rogério Monteiro-Oliveira, Yen-Ting Lin, Wei-Huai Chen +3
The advent of large integral field spectroscopic surveys has found that elliptical galaxies (EGs) can be classified into two classes: the fast rotators (whose kinematics are domina…
Ejective feedback as a quenching mechanism in the 1.5 billion years of the universe: detection of neutral gas outflow in a recently quenched galaxy
Po-Feng Wu
The confirmation of massive quiescent galaxies emerging within the first billion years of the universe poses intriguing questions about the mechanisms of galaxy formation. There mu…
Multiple Bipolar Molecular Outflows in the L1551 IRS5 Protostellar System
Po-Feng Wu, Shigehisa Takakuwa, Jeremy Lim
The multiple protostellar system L1551 IRS5 exhibits a large-scale bipolar molecular outflow. We have studied this outflow within ~4000 AU of its driving source(s) with the SubMill…
