STAR NRE: Solving supernova selection effects with set-based truncated auto-regressive neural ratio estimation
Konstantin Karchev, Roberto Trotta
Accounting for selection effects in supernova type Ia (SN Ia) cosmology is crucial for unbiased cosmological parameter inference -- even more so for the next generation of large, m…

Dark Matter Halo Parameters from Overheated Exoplanets via Bayesian Hierarchical Inference
MarÃa Benito, Konstantin Karchev, Rebecca K. Leane +3
Dark Matter (DM) can become captured, deposit annihilation energy, and hence increase the heat flow in exoplanets and brown dwarfs. Detecting such a DM-induced heating in a populat…
