Diffhalos: A Generative Model of Cosmological Lightcones of Dark Matter Halos
Georgios Zacharegkas, Andrew P. Hearin, Alan Pearl +3
We present a generative model of cosmological lightcones of dark matter halos, Diffhalos. In our model, we draw Monte Carlo samples of the halo mass function in a lightcone with a…

DiffstarPop: A generative physical model of galaxy star formation history
Alex Alarcon, Andrew P. Hearin, Matthew R. Becker +3
We present DiffstarPop, a differentiable forward model of cosmological populations of galaxy star formation histories (SFH). In the model, individual galaxy SFH is parametrized by…
