CECILIA: Using Flexible Photoionization Models to Accurately Measure Abundances without Auroral Lines
Nathalie A. Korhonen Cuestas, Allison L. Strom, Yijia Li +6
JWST has facilitated the detection of faint, auroral emission lines needed to directly measure the electron temperature and elemental abundances in high-redshift galaxies. However,…
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…
A Cosmic Miracle: A Remarkably Luminous Galaxy at Confirmed with JWST
Rohan P. Naidu, Pascal A. Oesch, Gabriel Brammer +43
JWST has revealed a stunning population of bright galaxies at surprisingly early epochs, , where few such sources were expected. Here we present the most distant example of t…
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…
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…
Quantifying the Effects of Known Unknowns on Inferred High-redshift Galaxy Properties: Burstiness, the IMF, and Nebular Physics
Bingjie Wang, Joel Leja, Hakim Atek +15
The era of the James Webb Space Telescope ushers stellar population models into uncharted territories, particularly at the high-redshift frontier. In a companion paper, we apply th…
JWST Observations of the Extraordinary GRB 221009A Reveal an Ordinary Supernova Without Signs of -Process Enrichment in a Low-Metallicity Galaxy
Peter K. Blanchard, V. Ashley Villar, Ryan Chornock +18
Identifying the astrophysical sites of the -process, one of the primary mechanisms by which heavy elements are formed, is a key goal of modern astrophysics. The discovery of the…
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…
A simple spectroscopic technique to identify rejuvenating galaxies
Junyu Zhang, Yijia Li, Joel Leja +4
Rejuvenating galaxies are unusual galaxies that fully quench and then subsequently experience a "rejuvenation" event to become star-forming once more. Rejuvenation rates vary subst…
Flexible Models for Galaxy Star Formation Histories Both Shift and Scramble the Optical Color-M/L Relationship
Yijia Li, Joel Leja
The remarkably tight relationship between galaxy optical color and stellar mass-to-light ratio () is widely used for efficient stellar mass estimates. However, it remains un…
