The host galaxies of FeLoBAL quasars at z$\sim$0.9 are not dominated by
  recent major mergers
  Theoretical models have suggested an evolutionary model for quasars, in which
most of luminous quasars are triggered by major mergers. It is also postulated
that reddening as well as powerful outflows indicate an early phase of
activity, close to the merger event. We test this model on a sample of quasars
with powerful low ionization outflows seen in broad Iron absorption lines
(FeLoBAL). This sample of objects show strong reddening in the optical and fast
($\sim$0.1c) high column density outflows. We present HST WFC3/IR F160W imaging
of 10 FeLoBAL host galaxies at redshifts z$\sim$0.9
($\lambda_{rest}\sim8500\AA$). We compare the host galaxy morphologies and
merger signatures of FeLoBALs to luminous blue non-BAL quasars from Villforth
et al. 2017 of comparable luminosity, which show no excess of merger features
compared to inactive control samples. If FeLoBAL quasars are indeed in a young
evolutionary state, close in time to the initial merging event, they should
have strong merger features. We find that the host galaxies of FeLoBAL quasars
are of comparable luminosity to the host galaxies of optical quasars and show
no enhanced merger rates. When looking only at quasars without strong PSF
residuals, an enhancement in disturbed and merger rates is seen. While FeLoBAL
hosts show weak enhancements over a control of blue quasars, their host
galaxies are not dominated by recent major mergers.
