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…
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…
Trading oxygen for iron II. Oxygen- versus iron-dependent cosmic star formation history
Martyna Chruślińska, 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…
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-…
Breaking Through the Cosmic Fog: JWST/NIRSpec Constraints on Ionizing Photon Escape in Reionization-Era Galaxies
Emma Giovinazzo, Pascal A. Oesch, Andrea Weibel +15
The escape fraction of Lyman continuum photons (fesc(LyC)) is the last key unknown in our understanding of cosmic reionization. Directly estimating the escape fraction (fesc) of io…
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…
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…
Ly with SPICE: Interpreting Ly emission at
Aniket Bhagwat, Lorenzo Napolitano, Laura Pentericci +2
Ly emission is key to understanding the process of cosmic reionisation. JWST is finally enabling us to measure Ly emission deep into the epoch of reionisation for an increasi…
SPICE: the connection between cosmic reionisation and stellar feedback in the first galaxies
Aniket Bhagwat, Tiago Costa, Benedetta Ciardi +2
We present SPICE, a new suite of RHD cosmological simulations targeting the epoch of reionisation. The goal of these simulations is to systematically probe a variety of stellar fee…
