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…
Origins of Extreme Emission-Line Ratios in z > 3 Galaxies: Insights from the Lumen Model
Lucie Scharré, Michaela Hirschmann, Adèle Plat +10
Optical emission-line ratios in star-forming galaxies at -8, such as [OIII]/H and [OIII]/[OII], are strongly offset from those at -2, pointing to more extrem…
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…
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…
DeepDive: A deep dive into the physics of the first massive quiescent galaxies in the Universe
K. Ito, F. Valentino, G. Brammer +26
We present the DeepDive program, in which we obtained deep JWST/NIRSpec G235M/F170LP spectra for ten primary massive () quiescent galaxies at $z\…
The Pandora project. II: how non-thermal physics drives bursty star formation and temperate mass-loaded outflows in dwarf galaxies
Sergio Martin-Alvarez, Debora Sijacki, Martin G. Haehnelt +11
Dwarf galaxies provide powerful laboratories for studying galaxy formation physics. Their early assembly, shallow gravitational potentials, and bursty, clustered star formation his…
The Noctua Suite of Simulations -- The Difficulty of Growing Massive Black Holes in Low-Mass Dwarf Galaxies
Jonathan Petersson, Michaela Hirschmann, Robin G. Tress +6
Aims. We study the individual and cumulative impact of stellar feedback processes on massive black hole (MBH) growth in a simulated low-mass dwarf galaxy. Methods. A suite of high-…
MISTRAL: a model for AGN winds from radiatively efficient accretion in cosmological simulations
Marion Farcy, Michaela Hirschmann, Rachel S. Somerville +11
Feedback from active galactic nuclei (AGN) is crucial for regulating galaxy evolution. Motivated by observations of broad absorption line winds from rapidly accreting supermassive…
A merging pair of massive quiescent galaxies at in the Cosmic Vine
K. Ito, F. Valentino, M. Farcy +26
We report the spectroscopic confirmation of a merging pair of massive quiescent galaxies at . Using JWST observations, we confirm that the two galaxies lie at a projected s…
Gas outflows in two recently quenched galaxies at z = 4 and 7
F. Valentino, K. E. Heintz, G. Brammer +33
Outflows are a key element in the baryon cycle of galaxies, and their properties provide a fundamental test for our models of how star formation quenches in galaxies. Here we repor…
You Shall Not Pass! The propagation of low/moderate powered jets through a turbulent interstellar medium
Olga Borodina, Yueying Ni, Jake S. Bennett +6
Feedback from black hole-powered jets has been invoked in many cosmological simulations to regulate star formation and quench galaxies. Despite this, observational evidence of how…
The impact of cosmic ray feedback during the epoch of reionisation
Marion Farcy, Joakim Rosdahl, Yohan Dubois +5
Galaxies form and evolve via a multitude of complex physics. In this work, we investigate the role of cosmic ray (CR) feedback in galaxy evolution and reionisation, by examining it…
The Effect of Cosmic Rays on the Observational Properties of the CGM
Daniel DeFelippis, Frédéric Bournaud, Nicolas F. Bouché +5
The circumgalactic medium (CGM) contains information on the cumulative effect of galactic outflows over time, generally thought to be caused by feedback from star formation and act…
