Abstract

Ultraluminous X-ray sources are thought to be powered by accretion onto a compact object; now the discovery of X-ray emission lines and blueshifted absorption lines in the high-resolution spectra of ultraluminous X-ray sources NGC 1313 X-1 and NGC 5408 X-1 shows that in each case the compact object is surrounded by powerful winds with an outflow velocity of about 0.2 times that of light.
