Scientific paper

We propose to perform a 130 ks observation of the Seyfert 1 galaxy H 0557-385, to obtain a high quality RGS spectrum of its very high column density ionised outflow (warm absorber). We will compare the properties of this outflow with those of closer, less luminous Seyferts to investigate how the outflow characteristics depend on luminosity. Since Seyfert warm absorbers are just a ghostly reminder of the much deeper, faster outflows in Broad Absorption Line quasars (BALQSOs), we will investigate whether this extreme object points towards the existence of an intermediate class of ionised outflow with properties somewhere between those of nearby Seyferts and luminous BALQSOs. This will provide an insight into how AGN outflows have evolved as the AGN population has dimmed with cosmic time.
