Modeling the JWST MIRI Counts, Insights Into the Source Properties and Role of Dust-Obscured AGN

Edgar P. Vidal, Anna Sajina, Amber R. Banks +8

Understanding the co-evolution of galaxies and active galactic nuclei (AGN) requires accurate modeling of dust-obscured systems. Recent surveys using the Mid Infrared Instrument (M…

High [OI] emission lines: ColdSIM simulations and ALMA observations

Massimiliano Parente, Manuela Bischetti, Umberto Maio +8

Neutral-oxygen [OI] far-infrared emission lines at m and m are powerful probes of the physical conditions in the interstellar medium, although they have not been fully…

Probing the Physics of Dusty Outflows through Complex Organic Molecules in the Early Universe

Andrey Vayner, Tanio Díaz-Santos, Carl D. Ferkinhoff +22

Galaxy-scale outflows are of critical importance for galaxy formation and evolution. Dust grains are the main sites for the formation of molecules needed for star formation but are…

Fine-structure Line Atlas for Multi-wavelength Extragalactic Study (FLAMES) I: Comprehensive Low and High Redshift Catalogs and Empirical Relations for Probing Gas Conditions

Bo Peng, Cody Lamarche, Catie Ball +5

Far-infrared (FIR) and mid-infrared (MIR) fine-structure lines (FSLs) are widely used for studying galaxies nearby and faraway. However, interpreting these lines is complicated by…
