Trading oxygen for iron II. Oxygen- versus iron-dependent cosmic star formation history
Martyna ChruÅliÅska, Mirko Curti, Ruediger Pakmor +4
Due to their different nucleosynthetic origin, a stellar population produces oxygen (O) and iron (Fe) on different timescales and their relative abundance can deviate strongly from…
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-…
Uncovering the absorbed atomic Universe with the [OI]63um line
Carlos De Breuck, Kevin C. Harrington, Wout Hermans +7
We report the discovery of strongly absorbed [OI]63um in a sample of 12 DSFGs at 4.2<z<5.8 selected from the SPT survey. This is the first systematic survey of the [OI]63um fine-st…
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…
