CAMELS: Feedback Effects in the WarmβHot CGM
In this study, we use data from the CAMELS simulation suite to explore how different subgrid implementations of stellar and AGN feedback affect the distribution of baryons in and around halos. We find that SIMBA's feedback model, while injecting less total energy than IllustrisTNG, more effectively expels gas beyond the halo boundary, suggesting that SIMBA's coupling to the surrounding medium is more efficient.
FRESCO: The Paschen-Ξ± Star-forming Sequence at Cosmic Noon
This work presents early results from the JWST First Reionization Epoch Spectroscopically Complete Observations (FRESCO) survey, focusing on galaxy star formation at 1.0 < z < 1.7. Using the Paschen-Ξ± emission line, which is less sensitive to dust than HΞ± or UV indicators, and rest-frame H-band magnitudes, we study the star-forming sequence at cosmic noon. Our results offer a cleaner, less dust-sensitive view of how galaxies build up their mass at z ~ 1.4.
