The Luminosity–Area Relation of z > 2 Quasars’ Lyα Nebulae

The Luminosity–Area Relation of z > 2 Quasars’ Lyα Nebulae

Cool ( T ∼ 10 ^4 K) gas is commonly observed around z > 2 quasars as traced by extended Ly α emission. These large-scale nebulae are usually studied using circularly averaged surface-brightness profiles, which suppress information on morphological differences. Here, we revisit the Ly α nebulae ar...
