Emission and absorption line features are important diagnostics for the physics underlying extragalactic astronomy. The interpretation of observed signatures involves comparing against forward modeled spectra from galaxy formation simulations as well as more simplified geometries, while including the complex scattering radiative transfer (RT) of resonant emission lines. We introduce thor, a modern C++ radiative transfer code focused initially on resonant emission lines. thor is a high-performance, distributed memory MPI-parallel, multi-target code, running on CPUs, GPUs and other accelerators, yielding large $\sim 10-50\rm{x}$ speed-ups compared to previous CPU-only codes.
cosmosTNG is a constrained cosmological galaxy formation simulation suite in the COSMOS field at Cosmic Noon. CLAMATO Lyman-alpha forest flux and zCOSMOS galaxy positions are used to reconstruct the initial density field, which is subsequently evolved with the TNG galaxy formation model with the AREPO code. The simulation suite consists of 8 variations of the unconstrained small-scale modes evolved down to $z\approx 2.0$, containing the well-studied zFIRE protocluster region, which furthermore overlaps with JWST treasury programs COSMOS-Web and PRIMER.
