[ascl:2312.009] GravSphere: Jeans modeling code
Read, J. I.; Steger, P.; Walker, M. G.; Genina, A.; Frenk, C. S.; Cole, S.; Benítez-Llambay, A.; Ludlow, A. D.; Navarro, J. F.; Oman, K. A.; Robertson, A.; Collins, M. L. M.; Ibata, R. A.; Rich, R. M.; Martin, N. F.; Peñarrubia, J.; Chapman, S. C.; Tollerud, E. J.; Weisz, D. R.

The non-parametric Jeans code GravSphere models discrete data and can be used to model dark matter distributions in galaxies. It can also recover the density ρ(r) and velocity anisotropy β(r) of spherical stellar systems, assuming only that they are in a steady state. Real or mock data are prepared by using the included binulator.py code; the repository also includes many examples for exploring the GravSphere's capabilities.

[ascl:2412.022] ForestFlow: Lyman-alpha cosmology emulator
Chaves-Montero, J.; Cabayol-Garcia, L.; Lokken, M.; Font-Ribera, A.; Aguilar, J.; Ahlen, S.; Bianchi, D.; Brooks, D.; Claybaugh, T.; Cole, S.; de la Macorra, A.; Ferraro, S.; Forero-Romero, J. E.; Gaztañaga, E.; Gontcho, S. Gontcho A; Gutierrez, G.; Honscheid, K.; Kehoe, R.; Kirkby, D.; Kremin, A.; Lambert, A.; Landriau, M.; Manera, M.; Martini, P.; Miquel, R.; Muñoz-Gutiérrez, A.; Niz, G.; Pérez-Ràfols, I.; Rossi, G.; Sanchez, E.; Schubnell, M.; Sprayberry, D.; Tarlé, G.; Weaver, B. A.

ForestFlow emulates the linear biases and small-scale deviation parameters of the 3D flux power spectrum of the Lyman-alpha forest. The parameters are modeled as a function of cosmology – the small-scale amplitude and slope of the linear power spectrum – and the physics of the intergalactic medium.
