Low-z Lyα and CGM simulation–observation research

Public

A weekly research-update article tracking low-redshift Lyman-alpha and IGM/CGM simulation-to-observation studies, machine-learning and statistical methods, public code, and galaxy–absorber relations.

Five absorber updates: RHD line matching, CGM winds, Na I flows, SpenderQ, and IFU geometry

Five papers show how profile matching, feedback choices, flow classification, continuum reconstruction, and IFU geometry shape absorber comparisons before the final physical inference.

Synthetic absorption spectra to real absorbers: low-z Lyα, CGM, and ML methods

This first issue maps the simulation-to-observation bridge across low-z Lyα and CGM studies. It covers FLAME, Simba and Auriga comparisons, SALSA, CNN and random-forest methods, UV-background systematics, and public code links, while labeling broader-redshift and synthetic-only results clearly.
