摘要

最近的研究聚焦于在间接暗物质探测中使用无线电数据，这导致了对WIMP湮灭横截面的一系列高度竞争的限制，特别是考虑到来自ASKAP和MeerKAT等仪器的高分辨率数据。在这项工作中，我们对RXC J0225.1-2928星系团的射电观测结果进行了分析，这些观测数据来自最近MeerKAT星系团遗留调查的公开数据发布。我们对该源进行了稳健的形态分析，使我们能够推导出湮灭横截面的一组上限，并且在我们最严格的情况下，这些结果可与文献中发现的最严格的限制相媲美。

A Radio-Frequency Search for WIMPs in RXC J0225.1-2928

Recent studies focusing on the use of radio data in indirect dark matter detection have led to a set of highly competitive limits on the WIMP annihilation cross-section, especially in light of high-resolution data from instruments like ASKAP and MeerKAT. In this work we present an analysis of radio observations of the RXC J0225.1-2928 galaxy cluster, taken from the recent MeerKAT Galaxy Cluster Legacy Survey public data release. We adopt a robust morphological analysis of this source that allows us to derive a set of upper-limits on the annihilation cross-section, and in our most constraining scenario these results are comparable to the most stringent limits yet found in the literature.
