All the Little Things in Abell 2744: 1000 Gravitationally Lensed Dwarf Galaxies at from JWST NIRCam Grism Spectroscopy

Rohan P. Naidu, Jorryt Matthee, Ivan Kramarenko +31

Dwarf galaxies hold the key to crucial frontiers of astrophysics, however, their faintness renders spectroscopy challenging. Here we present the JWST Cycle 2 survey, All the Little…

Unravelling the role of merger histories in the population of In situ stars: linking IllustrisTNG cosmological simulation to H3 survey

Razieh Emami, Lars Hernquist, Randall Smith +16

We undertake a comprehensive investigation into the distribution of in~situ stars within Milky Way-like galaxies, leveraging TNG50 simulations and comparing their predictions with…

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…

Cue: A Fast and Flexible Photoionization Emulator for Modeling Nebular Emission Powered By Almost Any Ionizing Source

Yijia Li, Joel Leja, Benjamin D. Johnson +5

The complex physics governing nebular emission in galaxies, particularly in the early universe, often defy simple low-dimensional models. This has proven to be a significant barrie…

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…

No top-heavy stellar initial mass function needed: the ionizing radiation of GS9422 can be powered by a mixture of AGN and stars

Yijia Li, Joel Leja, Benjamin D. Johnson +2

JWST is producing high-quality rest-frame optical and UV spectra of faint galaxies at for the first time, challenging models of galaxy and stellar populations. One galaxy rec…

Resolving the nature and putative nebular emission of GS9422: an obscured AGN without exotic stars

Sandro Tacchella, William McClymont, Jan Scholtz +27

Understanding the sources that power nebular emission in high-redshift galaxies is fundamentally important not only for shedding light onto the drivers of reionisation, but to cons…
