Ultra-Luminous X-ray Sources in Haro 11 and the Role of X-ray Binaries
  in Feedback in Lyman-alpha Emitting Galaxies
  Lyman Break Analogs (LBA) are local proxies of high-redshift Lyman Break
Galaxies (LBG). Studies of nearby starbursts have shown that Lyman continuum
and line emission are absorbed by dust and that the Lyman-alpha is resonantly
scattered by neutral hydrogen. A source of feedback is required to prevent
scattering and allow the Lyman-alpha emission to escape. There are two X-ray
point sources embedded in the Lyman Break Analog (LBA) galaxy Haro 11. Haro 11
X-1 is an extremely luminous (L$_{X} \sim 10^{41}$ ergs s$^{-1}$), spatially
compact source with a hard X-ray spectrum. Haro 11 X-1 is similar to the
extreme Black Hole Binary (BHB) M82 X-1. The hard X-ray spectrum indicates Haro
11 X-1 may be a Black Hole Binary (BHB) in a low accretion state. The very high
X-ray luminosity suggests an intermediate mass black hole that could be the
seed for formation of a supermassive black hole. Source Haro 11 X-2 has an
X-ray luminosity L$_{X} \sim 5\times10^{40}$ ergs s$^{-1}$ and a soft X-ray
spectrum. This strongly suggests that Haro 11 X-2 is an X-ray binary in the
ultra luminous state. Haro 11 X-2 is coincident with the star forming knot that
is the source of the Lyman-alpha emission, raising the possibility that strong
winds from X-ray binaries play an important part in injecting mechanical power
into the Interstellar Medium (ISM), thus blowing away neutral material from the
starburst region and allowing the Lyman-alpha to escape. We suggest that
feedback from X-ray binaries may play a significant role in allowing
Lyman-alpha emission to escape from galaxies in the early universe.
