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…

JWST observations of cosmic-ray-excited H in Barnard 68: spatial variations and constraints on cosmic-ray attenuation

David A. Neufeld, Kedron Silsbee, Alexei V. Ivlev +9

We present James Webb Space Telescope (JWST) NIRSpec observations of the starless dark cloud Barnard 68 that reveal the spatially-resolved signature of cosmic-ray excited molecular…

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…

Feeding the Dead: Neutral Gas Inflow in a Long-Quenched Ancient Massive Galaxy at Observed with JWST/NIRSpec

Davide Bevacqua, Danilo Marchesini, Paolo Saracco +16

We report the spectroscopic detection of neutral gas inflow into a massive () quiescent galaxy observed at with JWST. F…

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…

The first detection of cosmic-ray excited H in interstellar space

Shmuel Bialy, Amit Chemke, David A. Neufeld +12

Stars and planets form within cold, dark molecular clouds. In these dense regions, where starlight cannot penetrate, cosmic rays (CRs) are the dominant source of ionization -- driv…
