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…
Early Exploration of the Scientific Discovery Space for the Habitable Worlds Observatory
Courtney D. Dressing, Danica Adams, Evelyne Alecian +324
The Habitable Worlds Observatory (HWO) is a future NASA flagship mission concept identified by the Astro2020 Decadal Survey as the highest priority for large space missions. HWO sh…
Fishing for Jellyfish Galaxies: Exploring ram-pressure stripping with crowd science
C. Bellhouse, Y. L. Jaffé, J. P. Crossett +13
Aims: We present the first results of Fishing for Jellyfish Galaxies, a pilot citizen-science project using Zooniverse to identify galaxies undergoing ram-pressure stripping (RPS).…
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…
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…
Negative gas-phase metallicity gradients in the narrow line region and galactic disc of local AGN-host galaxies
Amirnezam Amiri, Johan H. Knapen, Bret D. Lehmer +1
The gas-phase metallicity distribution in galaxies provides significant information on their evolution. We report the discovery of negative radial gradients in the gas-phase metall…
Death by Impact: Evidence for Merger-Driven Quenching in a Collisional Ring Galaxy at Cosmic Noon
Amir H. Khoram, Sirio Belli, Carlo Nipoti +7
The role of interactions and mergers in the rapid quenching of massive galaxies in the early Universe remains uncertain, largely due to the difficulty of directly linking mergers t…
Empirical Calibration of Na I D and Other Absorption Lines as Tracers of High-Redshift Neutral Outflows
Lorenzo Moretti, Sirio Belli, Gwen C. Rudie +5
Recent JWST observations of massive galaxies at z > 2 have detected blueshifted absorption in Na I D and other resonant absorption lines, indicative of strong gas outflows in the n…
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…
The interplay between Active Galactic Nuclei and Ram-pressure stripping: spatially resolved gas-phase abundances of stripped and undisturbed galaxies
Giorgia Peluso, Benedetta Vulcani, Mario Radovich +11
The gas-phase oxygen abundance of the circumnuclear regions around supermassive black holes (SMBH) has been claimed to be affected by the presence of an Active Galactic Nucleus (AG…
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…
Stripped and Enriched: The Role of Ram-Pressure in Shaping Chemical Enrichment of Galaxies at Intermediate Redshift
Amir H. Khoram, Bianca Poggianti, Alessia Moretti +11
The chemical evolution of galaxies is shaped by their star formation histories and the exchange of gas with their environments. Metallicity provides key insights into these process…
Direct-method metallicity gradients derived from spectral stacking with SDSS-IV MaNGA
Amir H. Khoram, Francesco Belfiore
Chemical abundances are key tracers of the cycle of baryons driving the evolution of galaxies. Most measurements of interstellar medium (ISM) abundance and metallicity gradients in…

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…
