Cover Story: The cover image shows the three-dimensional distribution of synchrotron intensity (in units of micro-Jansky pixel^-1) at 1.5 GHz of a transonic turbulent medium generated from magnetohydrodynamic simulations (Burkhart et al. 2009, ApJ, 693, 250). All intensity fluctuations are caused due to fluctuations of the magnetic field strength in the plane of the sky. The synchrotron intensity is computed using the COSMIC package presented in Basu et al., and performs polarization transfer calculations including the effects of Faraday rotation to generate realistic synthetic observations.

One possible and natural derivation from the collisionless cold dark matter (CDM) standard cosmological framework is the assumption of the existence of interactions between dark matter (DM) and photons or neutrinos. Such a possible interacting dark m...
