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…

Phase Space Distribution Functions and Energy Distributions of Dark Matter Particles in Haloes

Axel Gross, Zhaozhou Li, Yong-Zhong Qian

For a spherical dark matter halo with isotropic velocity distribution, the phase space distribution function (DF), the energy distribution, and the density profile form a set of se…

A Data-Driven Model for Abundances in Metal-poor Stars and Implications for Nucleosynthetic Sources

Axel Gross, Zewei Xiong, Yong-Zhong Qian

We present a data-driven model for abundances of Fe, Sr, Ba, and Eu in metal-poor (MP) stars. The production patterns for core-collapse supernovae (CCSNe) and binary neutron star m…
