Stellar feedback SPICEs up [C II] emission in the first galaxies

Aniket Bhagwat, Tiago Costa, Benedetta Ciardi +1

The bright [C II] 158 micron line is widely used to trace star-forming gas and feedback-driven outflows in high-redshift galaxies. Using the SPICE simulations, we investigate how b…

New constraints on stellar feedback through [O III] emission: interpreting ALMA and JWST observations with SPICE simulations

Benedetta Casavecchia, Aniket Bhagwat, Benedetta Ciardi +2

ALMA and JWST have recently detected emission lines from the interstellar medium of star-forming galaxies during the Epoch of Reionization, reaching redshifts up to z = 14. Among t…

Metallicity Gradients in Modern Cosmological Simulations II: The Role of Bursty Versus Smooth Feedback at High-Redshift

Alex M. Garcia, Paul Torrey, Aniket Bhagwat +22

The distribution of gas-phase metals within galaxies encodes the impact of stellar feedback on galactic evolution. At high-redshift, when galaxies are rapidly assembling, feedback-…

Variability of the UV luminosity function with SPICE

Arghyadeep Basu, Aniket Bhagwat, Benedetta Ciardi +1

We investigate the variability of the UV luminosity function (UVLF) at using the SPICE suite of cosmological, radiation-hydrodynamic simulations, which include three distin…

Metallicity Gradients in Modern Cosmological Simulations I: Tension Between Smooth Stellar Feedback Models and Observations

Alex M. Garcia, Paul Torrey, Aniket Bhagwat +14

The metallicity of galaxies, and its variation with galactocentric radius, provides key insights into the formation histories of galaxies and the physical processes driving their e…
