Most important metal absorptions of intergalactic medium that imprint correlations observed in Lyα–quasar cross-correlation for r∥ ∈ [ − 200, 200] h−1 Mpc.
| Metal line | λm [nm] | λ1/λ2 |
 |
|---|---|---|---|
| SiII(119.0) | 119.04 | 1.021 | −59 |
| SiII(119.3) | 119.33 | 1.019 | −53 |
| SiIII(120.7) | 120.65 | 1.008 | −21 |
| SiII(126.0) | 126.04 | 1.037 | +103 |
Notes. The second column lists the rest-frame wavelength of the metal line and the third column its ratio with λα (using the shorter of the two wavelengths in the denominator). The last column gives the apparent radial distance difference between the Lyα and metal absorption, r∥ = Dc(zα)−Dc(zm), for observed wavelength λ = 407.2 nm (corresponding to Lyα absorption at zeff = 2.35).
