[ascl:2211.020] EXCEED-DM: EXtended Calculation of Electronic Excitations for Direct detection of Dark Matter
Trickle, Tanner; Inzani, Katherine; Griffin, Sinéad M.; Zhang, Zhengkang; Zurek, Kathryn M.
EXCEED-DM (EXtended Calculation of Electronic Excitations for Direct detection of Dark Matter) provides a complete framework for computing DM-electron interaction rates. Given an electronic configuration, EXCEED-DM computes the relevant electronic matrix elements, then particle physics specific rates from these matrix elements. This allows for separation between approximations regarding the electronic state configuration, and the specific calculation being performed.
[ascl:2510.015] SpyDust: Improved implementation of SPDust for modeling spinning dust radiation
Zhang, Zheng; Chluba, Jens
SpyDust models spinning‑dust emission in astrophysical environments using a Python‑based framework. Building upon SPDUST (ascl:1010.016), SpyDust offers enhanced capabilities and corrections. It implements extended treatments of grain shape, dipole radiation back‑reaction, and plasma. Users supply environmental parameters (e.g., hydrogen density, temperature, ionization fractions) and the code computes emission spectra across specified frequency ranges. SpyDust supports optional MPI‑based parallel execution and provides Jupyter notebook examples for workflow demonstration.
