Field-Level Inference from Galaxies: BAO Reconstruction
Adrian E. Bayer, Liam Parker, David Valcin +3
Baryon acoustic oscillations (BAO) underpin the key cosmological results from modern spectroscopic galaxy surveys, but nonlinear gravitational evolution limits the precision achiev…
Galactification: painting galaxies onto dark matter only simulations using a transformer-based model
Shivam Pandey, Christopher C. Lovell, Chirag Modi +1
Connecting the formation and evolution of galaxies to the large-scale structure is crucial for interpreting cosmological observations. While hydrodynamical simulations accurately m…
FLORAH-Tree: Emulating Dark Matter Halo Merger Trees with Graph Generative Models
Tri Nguyen, Chirag Modi, Siddharth Mishra-Sharma +2
Merger trees track the hierarchical assembly of dark matter halos across cosmic time and serve as essential inputs for semi-analytic models of galaxy formation. However, convention…
Teaching dark matter simulations to speak the halo language
Shivam Pandey, Francois Lanusse, Chirag Modi +1
We develop a transformer-based conditional generative model for discrete point objects and their properties. We use it to build a model for populating cosmological simulations with…
Characterising ultra-high-redshift dark matter halo demographics and assembly histories with the GUREFT simulations
L. Y. Aaron Yung, Rachel S. Somerville, Tri Nguyen +3
Dark matter halo demographics and assembly histories are a manifestation of cosmological structure formation and have profound implications for the formation and evolution of galax…
