Query: On the observability of coupled dark energy with cosmic voids   Taking N-body simulations with volumes and particle densities tuned to match
the SDSS DR7 spectroscopic main sample, we assess the ability of current void
catalogs (e.g., Sutter et al. 2012b) to distinguish a model of coupled dark
matter-dark energy from {\Lambda}CDM cosmology using properties of cosmic
voids. Identifying voids with the VIDE toolkit, we find no statistically
significant differences in the ellipticities, but find that coupling produces a
population of significantly larger voids, possibly explaining the recent result
of Tavasoli et al. (2013). In addition, we use the universal density profile of
Hamaus et al. (2014) to quantify the relationship between coupling and density
profile shape, finding that the coupling produces broader, shallower,
undercompensated profiles for large voids by thinning the walls between
adjacent medium-scale voids. We find that these differences are potentially
measurable with existing void catalogs once effects from survey geometries and
peculiar velocities are taken into account.
