A Data-Driven Model for -Process Production Patterns
Chen-Qi Li, Yong-Zhong Qian, Axel Gross +1
Using the elemental abundances in 68 metal-poor (MP) stars, we present a data-driven model for -process production patterns covering Sr to U. We show that essentially all the $r…

Let there be neutrons! Hadronic photoproduction from a large flux of high-energy photons
Matthew R. Mumpower, Tsung-Shung H. Lee, Nicole Lloyd-Ronning +4
We propose that neutrons may be generated in high-energy, high-flux photon environments via photo-induced reactions on pre-existing baryons. These photohadronic interactions are ex…

Scaling Relations in the Phase-Space Structure of Dark Matter Haloes
Axel Gross, Zhaozhou Li, Yong-Zhong Qian
We present new scaling relations for the isotropic phase-space distribution functions (DFs) and energy distributions of simulated dark matter haloes. These relations are inspired b…
