Abstract

We construct a simple, spherical blast wave model to estimate the pressure structure of the intergalactic medium surrounding hyperstarburst galaxies, and argue that the effects of interaction with star-forming galaxy winds may be approximated at early times by an adiabatically expanding, self-similar ‘bubble’ as described by Weaver et al. and Ostriker & McKee. This model is used to make observational predictions for the thermal Sunyaev–Zel'dovich effect in the shocked bubble plasma. Radiative cooling losses are explored, and it is found that bremsstrahlung will limit the epoch of adiabatic expansion to 107– 108 yr: comparable to total hyperstarburst lifetimes. Prospects for making a first Sunyaev–Zel'dovich detection of galaxy wind bubbles using the Atacama Large Millimeter Array are examined for a number of active hyperstarburst sources in the literature.
