The Cosmological Bias Factor of Damped Lyman Alpha systems: Dependence on Metal Line Strength

Ignasi Pérez-Ràfols, Jordi Miralda-Escudé, Andreu Arinyo-i-Prats +2

We measure the cosmological bias factor of DLAs from their cross-correlation with the Ly$\alpha$ forest absorption, as a function of the DLA metal strength, defined from an average of e…
