The Power Spectrum of the Lyman-$\alpha$ Forest at z < 0.5

Vikram Khaire, Michael Walther, Joseph F. Hennawi +6

We present new measurements of the flux power-spectrum P(k) of the $z<0.5$ HI Lyman-$\alpha$ forest spanning scales k ~ 0.001-0.1 s/km. These results were derived from 65 far ultraviole…
