AI-assisted super-resolution cosmological simulations V: Cosmology-aware super-resolution
Xiaowen Zhang, Patrick Lachance, Rupert A. C. Croft +2
We present a cosmology-aware generative model for super-resolution (SR) of cosmological -body simulations in particle phase space. The model jointly generates displacements and…
The lifetimes and properties of Little Red Dots in the AMBRA simulation
Patrick LaChance, Yihao Zhou, Aklant Kumar Bhowmick +6
We identify and analyze the little red dots (LRDs) in the AMBRA cosmological hydrodynamic simulation, by producing mock observations of the galaxies and active galactic nuclei (AGN…
Theoretical emission lines and metallicity calibrations of H II regions in ASTRID simulation
Yao Yao, Kathryn Grasha, Stuart Wyithe +5
We present a theoretical framework to derive redshift-dependent metallicity calibrations for galaxies at =2-7. The ionization parameter () and gas pressure () in our appro…
The Galaxy Luminosity Functions in ASTRID: Predictions for LSST
Fatemeh Hafezianzadeh, Tianqing Zhang, Paul Rogozenski +6
We present validated and forward-modelled galaxy luminosity functions and photometric predictions for the Vera C. Rubin Observatory Legacy Survey of Space and Time using the ASTRID…
First results of AMBRA: Abundant Seeds and Early Mergers as a Pathway to the First Massive Black Holes
Yihao Zhou, Aklant Kumar Bhowmick, Tiziana Di Matteo +6
AMBRA combines the large cosmological volume and statistical power of ASTRID with the physically motivated gas-based black hole seeding models from BRAHMA. Motivated by JWST's disc…
