Description
Indirect dark matter searches have historically concentrated on the nearby universe. In this work we explore whether higher redshift objects $z \gtrsim 0.1$ could be an under-utilised resource in the search for the fundamental nature of dark matter. We do so by exploring MeerKAT observations of higher redshift galaxy clusters and considering current and future gamma-ray experiment sensitivities to emissions from these objects. Our results indicate that individual distant galaxy clusters offer somewhat competitive limits. However, their true value may be in the large number of these objects, allowing a large-scale joint analysis.
