- Effort.jl is a new emulator that can run complex cosmic simulations on a standard laptop with high accuracy.
- Traditionally, such simulations required supercomputers due to their computational intensity.
- Effort.jl combines neural networks with physical knowledge to drastically reduce computation time.
- The emulator mimics the behavior of models like EFTofLSS, which describe the large-scale structure of the Universe.
- Effort.jl has been validated to produce results that closely match those of the original models, sometimes even with finer detail.
- The tool is particularly useful for analyzing large datasets from upcoming astronomical surveys like DESI and Euclid.
- Effort.jl uses gradients and pre-existing knowledge to reduce the training phase and computational needs.
- The study confirms Effort.jl's accuracy on both simulated and real data, making it a valuable tool for future cosmological research.
