The 1D flux power spectrum of the Lyman-Alpha forest ($P_{1D}$), measured by surveys like eBOSS and DESI, probes the matter power spectrum on small scales ($k \sim 1$ h/Mpc) at high redshifts ($z \sim 3$). A persistent 3-5$\sigma$ tension exists between these measurements and the predictions of Planck $\Lambda$CDM. Specifically, the Lyman-Alpha data prefers a lower amplitude of small-scale fluctuations (lower $\sigma_8$ or effective tilt) than the CMB extrapolation predicts. This "deficit" of small-scale power has been interpreted as a hint for non-zero neutrino masses, running spectral index ($\alpha_s$), or Warm Dark Matter (WDM), which would suppress structure growth on these scales (Palanque-Delabrouille et al. 2020; Rogers et al. 2024).
