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…
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…
From THESAN-ZOOM to JWST: Predicting ionizing photon escape and the rise of UV-bright reionization sources
Zebedee Summerfield, William McClymont, Sandro Tacchella +14
Understanding the sources and evolution of cosmic reionization remains a central challenge in astrophysics, with the escape of ionizing Lyman-continuum (LyC) photons from early gal…
The Blue Jay Survey: Deep JWST Spectroscopy for a Representative Sample of Galaxies at Cosmic Noon
Sirio Belli, Letizia Bugiani, Minjung Park +17
We present the Blue Jay survey, a cycle 1 JWST program aimed at studying the stellar and gas content of galaxies at cosmic noon. The survey consists of deep spectroscopy for 153 ta…
Probing neutral outflows in z ~ 2 galaxies using JWST observations of Ca II H and K absorption lines
Caterina Liboni, Sirio Belli, Letizia Bugiani +12
Using deep JWST/NIRSpec spectra from the Blue Jay survey, we perform the first systematic investigation of neutral gas content in massive galaxies at Cosmic Noon based on the Ca II…
Big, Dusty Galaxies in Blue Jay: Insights into the Relationship Between Morphology and Dust Attenuation at Cosmic Noon
Gabriel Maheson, Sandro Tacchella, Sirio Belli +10
The dust attenuation of galaxies is highly diverse and closely linked to stellar population properties and the star dust geometry, yet its relationship to galaxy morphology remains…
AGN Feedback in Quiescent Galaxies at Cosmic Noon Traced by Ionized Gas Emission
Letizia Bugiani, Sirio Belli, Minjung Park +17
We analyze ionized gas emission lines in deep rest-frame optical spectra of 16 quiescent galaxies at redshift observed with JWST/NIRSpec by the Blue Jay survey. Robust…
Widespread rapid quenching at cosmic noon revealed by JWST deep spectroscopy
Minjung Park, Sirio Belli, Charlie Conroy +16
Massive quiescent galaxies in the young universe are expected to be quenched rapidly, but it is unclear whether they all experience starbursts before quenching and what physical me…
Observational Signatures of AGN Feedback in the Morphology and the Ionization States of Milky Way-like Galaxies
Nadia Qutob, Razieh Emami, Kung-Yi Su +24
We make an in-depth analysis of different AGN jet models' signatures, inducing quiescence in galaxies with a halo mass of . Three jet models, including cosmic ray-…
JWST Reveals Widespread AGN-Driven Neutral Gas Outflows in Massive z ~ 2 Galaxies
Rebecca L. Davies, Sirio Belli, Minjung Park +15
We use deep JWST/NIRSpec R~1000 slit spectra of 113 galaxies at 1.7 < z < 3.5, selected from the mass-complete Blue Jay survey, to investigate the prevalence and typical properties…
Star Formation Shut Down by Multiphase Gas Outflow in a Galaxy at a Redshift of 2.45
Sirio Belli, Minjung Park, Rebecca L. Davies +15
Large-scale outflows driven by supermassive black holes are thought to play a fundamental role in suppressing star formation in massive galaxies. However, direct observational evid…
Unravelling the Dust Attenuation Scaling Relations and their Evolution
Gabriel Maheson, Roberto Maiolino, Mirko Curti +3
We explore the dependence of dust attenuation, as traced by the Balmer decrement, on galactic properties by using a large sample of SDSS spectra. We use both Part…
The chemical enrichment in the early Universe as probed by JWST via direct metallicity measurements at z~8
M. Curti, F. D'Eugenio, S. Carniani +30
We analyse the chemical properties of three z~8 galaxies behind the galaxy cluster SMACS J0723.3-7327, observed as part of the Early Release Observations programme of the James Web…
